This time, Joe is safely vaccinated for the evening.

“Okay.” Mason says as he thwacks the syringe of Joe’s regular dosage of lycanthropy vaccine “I spoke with the usual nurses who actually know you, and they gave me your allotted medicine for the week. Your substitute doctor wasn’t please, but neither was the werehippo she treated the same as you.”

“Cool. I need the sleep, to be honest.” Joe says as he ties the tourniquet on his own arm “As much as I’d like to fuck your brains out all night, that midterm is crucial for my scholarship.”

“Well let’s not rule that out, handsome.” Mason grins “You’re a still a fat hairy bombshell, fur or not.”

“Heheheh” Joe holds out his arm and watches as Mason lines the needle to his vein and sticks him. Mason administers drains the solution and caps the syringe and tosses it to the bin before getting a fresh one for himself.

“And for me.” Mason injects himself with his own dose of ANTI-LYCAN to prevent infection and packs up the medic kit “And we’re done.”

“Great. Now where the hell is my lollipop?” Joe smiles and grinds against his boyfriend.

“You’ll get your lolli when I get my soufflé, fatty.” Mason snickers as the two of them leave the bathroom.

The two of them spend the evening cuddling on the couch and munching on popcorn while watching a movie.

“I still don’t get why people hate this movie so much. McCarthy is brilliant in this!” Mason says as he gestures to the screen before sampling more of his pink soufflé with a slice of strawberry.

“I’m not sure either.” Joe says as they watch Sherri Shepherd turn invisible “I mean, I’ve seen a lot of superhero movies, and this one IS missing something, I just can’t pinpoint what.”

“You know me, I’m more of a fantasy fan than a hero fan, so I wouldn’t know. I just think Melissa’s hilarious.” He comments while they watch the movie.

“… Achem… Hrrrmm…” Joe furrows his brow and coughs as he grimaces when his stomach starts to churn. “Oorrff… F-Fuck…”

“You okay, babe?”

“Y-Yeah, I’m fine…” Joe grunts as his limbs start to hurt. Mason glances up and down as he hears some stretching and clenching sounds come from Joe’s muscles along with the deep cracking of his bones beneath the loud bubbling and gurgling in Joe’s round and bouncy gut “I think I’m starting to change.”

“Oh alright. I’m right here, babe.” Mason turns and puts his hands on his lover’s darkening flesh.

“I’m fFUuckKinG fine, Mason.” Joe snarls painfully as his he writhes on the spot, tensing and jerking as his body undergoes the involuntary transformation. “I’ve done this a million FFFFFUufucCCkinNg times” Joe grits his teeth as he feels heavier with both fat and muscle.

“I know, it’s just hot to watch.” Mason grins as he sees the outbreak of thick hair on Joe’s arms and legs before his tummy starts to balloon.

“Hrrrf, hooohh, mnngghhh!” Joe clenches his eyes as he get even fatter. His belly thickly gurgles as it rises like a large beachball before the pink tint of his navel darkens across in a black shade. His chest bloom into strong manboobs while his arms and legs crack and bulge with invasive muscle.

“RRRggghhh!” Joe rolls over and fumbles onto the floor and “Haahh… Hahh… Haahh… GGHHHHRRRHH!” He pants and snarls with hard strain as his backside becomes enveloped in his thick black fur coat. Mason watches lewdly at that those briefs as Joe’s butt fills in promptly “Hoh, hoh, hoh, hoh, hoh, GGHHHHH!” His asscheeks weight into his underwear until those briefs sink against his swelling flesh and become skin-tight to develop a glorious Plumber’s Crack while those thighs creak with power and the round pouch of Joe’s genitals lower down as they too grow in size.

“BUWAaaahh! Hahhh… Hahhh… Hahhh…” Joe pants as his face finally finishes wrinkling and morphing to finish the transformation. He is not nearly as big as he was last night, but he has definitely doubled in girth and stature.

“Jesus fucking Christ…” Joe says, his voice a lot deeper than his own. He breathes harshly as his body tingles with bits of pain while his brain pushes away a headache; the vaccine is definitely working in keeping him ‘HIM’ “It never gets easier… Oof” The monkey man blinks and looks over his furry shoulder.

“Mmmhhhh, soooooo fucking hooooot” Mason says as he nuzzles across that massive cushion ass.

“Hurgh hurgh hurgh” Joe chuckles as his right foot-hand reaches over and pushes the back of Mason’s head into his rump. “You enjoying the view, babe?”

“God, you’re giving me such a boner right now.” Mason says as he rubs his hands across that big butt.

Joe gets up and sits on the couch… Or at least tries to “W-Whoa!” His body slips down and hits the floor, making his enormous belly and moobs bounce and ripple from impact. “Heh heh… Guess the couch ain’t happening?”

“That’s okay, I got my own squishy beanbag~!” Mason hops onto Joe’s lap and snuggles onto that big flabby ape-man. “Good to hear you talk again.”

“Hurgh, right?”

“Especially since that voice of yours is so fucking hot.”

“Hergh hergh~ If this form makes you THIS easy, maybe I should go in for treatment routine to let me change whenever I want.”

“But then it wouldn’t be special.” Mason says.

“Oh come on” Joe grins as his enlarged hands go up and cup his moobs and roll his nipples “You wouldn’t want a piece of this every night? Or THIS?” He grins wider as he makes his flaccid bulge in his stretched underwear push and rub into Mason’s bottom.

“Oh no. I couldn’t get ENOUGH of all this.” Mason dry humps that mobile gut “But your full moons are special, it gives me a lot to look forward to. I love everything about you, human AND animal. Besides, those treatments are risky, and I don’t want you to change more than called for.”

“You fuggin sap~” Joe puckers his lips and kisses Mason’s face.

The two of them continue the movie with Mason sitting on Joe’s lap and resting on his jello tummy as Joe snacks on a loaf of banana bread.

Mason moans as he rubs his bare back against Joe’s enormous gut with his underwear tight with a boner. He remembers back when he and Joe were first dating; Joe was such an adorable geek. He was just Mason’s type aside from his very small penis; Mason’s a switch by nature, but Joe could never hump Mason unless he was in animal form, and even that took a lot of adjustment.

They’ve been together for 3 years now.

Dating a lycanthrope isn’t always easy – there’s a lot of medical and physiological effort that has to go into it in managing the feral side effects of the full moon while also having to always be on top of the biological stand-point of keeping cross-contamination in check.

<<fill in>>

The movie reaches its conclusion, with the super strong heroine having her happy ending with a former antagonist with crab claws. Mason comes back after putting away their dinner and gets turned on when he sees his beefy ape stud get up.

“So.” Joe says as he gets up and stretches his back. Mason just stares with famished eyes as that perfect round stomach juts out as Joe’s back arches and cracks. Joe huffs and causes his girth to wobble free and smiles at his lover “We got some time before bed. Regular classes tomorrow, regular shift at job.” Joe grins and nods to the bedroom “Whadya say you and me go in and get wild~?”

“Oh fuck, yes” Mason says as he springs up. Joe chuckles as he leads the way, letting his boyfriend get a full view of his big fat ass.

In the bedroom, Joe sits on his huge behind and spreads his legs to allow his bulge to lure Mason in. Mason crawls between those large thighs and shoves his face into that package. “Hhhhhhhhh…” Mason takes a deep whiff of Joe’s musky crotch and starts to nuzzle the flaccid member contained within. “Fffffffffffuuuuuuuuuck” Mason huffs as he shoves his nose down the subtle divide of those kiwi-sized balls.

Mason giggles as he feels Joe’s feet rub his butt and the other grab the back of his head. Joe smirks as he puts his hands behind his head and pushes Mason’s head into his crotch with his foot. Mason finally pulls down that tight underwear down and let loose that floppy lengthened dong. “Haaalllhh” Mason takes the mushroom head into his mouth and starts to nurse it.

“O-Ooo… Oh baby” Joe shudders and huffs. Mason glances up and see that massive balloon-esque belly expand and then deflate, boom and then shrink. Seeing that recurring inflation is such a turn-on. Mason adjusts his jaw and starts to take that huge cock to the base. “H-hOHH! HaaahhHHH! Ohhh Mason, MMFF!” His foot starts pumping Mason’s head back and forth as he kicks back, his hand-like appendage almost masturbating with his boyfriend’s face. “Fuck, no one does this better than you.”

Joe’s foot lets go of Mason’s head and he gasps for breath. “Hahhh… Hahhh…” Mason gets up and lays himself onto the gelatinous gut. Joe grins as one of his hands holds him up to his face while Mason sensually humps his bellybutton. Their tongues suck on each other as they make out passionately before Joe’s mouth pops in surprise “OOOHH!””

“Yeah” Mason grins as his foot smashes down on those enlarged testicles. “You like that, babe/”

“Ohhhhhh you know I fuggin DOOOOO!” Joe’s voice leaps as that foot shoves down on his nuts! “Ah-HOOO! Ahahhh” Joe’s cock jumps from Mason grinding his sac harshly.

“Say what I like to hear.” Mason says as he rubs his hands on Joe’s cheeks.

“HiiiiiiilooovveyooouuuUUUU!” Joe flinches and jerks as that foot kicks his tenders. “UHHH! NNHH!”

“Yeah, I can never get away with this in your human form.” Mason says as his foot rolls those orbs around. Joe’s eyes cross as his tongue lolls out goofily. Mason stomps on those babymakers again and immediately gets a jumbled reaction

“AAaaahhh~!”

“Yeah, you’re my big horny beast” Mason woos as he kisses that big goofy mouth. “You’re my huge stupid monkey.”

“Yeeeaaaah I aaaaammm” Joe squeals as his balls get stepped on again. “Fuck, I love you”

“I love you too, you fat hairy fucker.” Mason hisses as he gives those balls one last hard KICK!

“OOOOOHHH!” Joe’s hands go to clutch his manhood that time and curls on the floor and clenches his eyes shut. “NNnnhnhnhnhnhnhnnn!

“O-Oh shit, I’m sorry, babe!” Mason frets “Was that too hard??”

“Noooo nooo” Joe shakes his head and bites his juicy lower lip. Mason sighs as he sees a horny grin “I almost fucking came, MMHHHH” Regardless, he grimaces and holds his balls firmly – truthfully it WAS a little too hard, but he did almost ejaculate.

“Oh good. Don’t scare me like that.” He gives that rump a smack. Mason smiles as he rolls Joe to the side so he’s on his knees. Joe giggles and arches his back to further present himself like the bottom he always is. “God, your ass is HUGE.” Mason takes a pair of scissors and snips at the gorilla’s perineum.

“GHH! Ooh! Easy back there! SSSSH! Ahh, careful!” Joe frets as Mason cuts and snips away at the underpants. Once Mason’s cutting was halfway through, the rest of the briefs tore on its own as Joe’s mighty rump bounces forth and juts from the white tatters of the elastic undies. “Whhheeeeeew… Much better.” Joe sighs as his bottom breathes naked and free.

“Alright.” Mason grins as he slaps that huge booty “Ready to get fucked, babe?”

“Huh?” Joe looks up and over his shoulder and scoffs “Hahahahah, babe. We both know you can’t fuck MY ass when I’m like this.” He reaches back and opens his colossal cheeks to expose his swollen pucker “Even if I spead out, your dick’s not going to fit!”

“Actually I got something after the full moon last month.” Mason says as he walks to the closet.

“Hm?” Joe gets up on his feet and struts over to his boyfriend.

“Check it oooouuuut!” Mason says as he brandishes a large wobbly dildo-strap on with both hands – this thing is as long as his arm!”

“Pfffff, hahahahaah” Joe pics it up and wobbles it around playfully, “Mason, aren’t these for women? It’s not going to fit on your dick.”

“No, see” Mason says as he takes it back and turns it around, showing a sort of squishy pocket tucked within the silicone gel cock “This is a custom-made dildo that has a cocksleeve for this attachment. I tried it on a while back and my dick slips in fairly easily. The only drawback is I had to remove its vibrator function for it to work. And it’s too heavy for any long thrusts.”

“In other words” Joe snickers “The receipt is useless because you butchered the warranty.”

“It means I can plow your deep crack.” Mason slaps that hung round belly.

“Heh, alright babe” Joe bends down for a hot kiss and walks to the bed “But when that thing can’t reach my hole, I’m strapping you to the bed and fucking you like a doll.”

“Win-win.” Mason smirks as he follows Joe. Joe sets himself down on the mattress and kneels down. Mason hefts the massive log and plops onto those twin furry jello mounds.

“I’m waiting” Joe teases as his manly gorilla butt flexes and even gives a playful twerk.

“Working on it.” Mason rolls his eyes as he clicks the strap-on into place around his pelvis, around his waist, under his butt, nestle his balls, and slides his erect member into the cocksleeve. “O-Oooo…” He shudders before he pops the bottle off lube pours a very generous amount of it on the silicone penis.

Joe looks over his shoulder and waves his huge rump left and right to entice his lover. “You’re just wasting all that lube ya know.”

“Save your comments AFTER I fucking **** you, monkeybutt.” Mason says as he aligns the strap-on into Joe’s deep divide.

“Yeeep. Meanwhile I’m staining the bed with my precUH!” His head shoots up when his pucker meets with a large object “CuuuhhhHH~” He moans as his anust feels the familiar forceful push. “Hoo, hoo, hoo, AH-hem!” He coughs as his left leg starts to jump up and down.”

“W-Whoa, easy there” Mason steadies himself on Joe’s furry back as that huge pucker flexes and yawns around that huge dildo. “Joe, Joe, Joe, Joe, EASY!”

In one second and a loud schlorping sound, Joe’s asshole SUCKS that enormous strap-on. “U-Uhh! Babe, stop!” Mason staggers as his front is pulled between Joe’s fluffy buttcheeks. He irks and adjusts himself by putting one foot on the bed and keeping the other foot rooted to the floor and pulls his cock back.

“O-OOHHH!” Joe moans out as his anus squeezes around that colossal penis. “HohhhH! OOHHhh! Hooohhh! OOoooohhh!” His fists creak out the mattress as his back arches as his hole gets drilled into “Oh babe this feels FUCKING phenominal!” The ape bites the bed as his globe-like ass bounces with each methodical thrust Mason sends down his butt.

“Oh God, this IS fucking different.” Mason moans as he humps Joe downward into that deep butt. Joe’s donut-like sphincter squelches hungrily around that silicone log. Mason’s own cock is squished from all sides from the lubricated cock sleeve built inside and gives him his own side of pleasure.

“Haawww! Haaawwww! Aaahhhhwww” Joe moans constantly as his meaty arms hugs the bed while with his mouth stays wide open “Awwww fuck, I haven’t had a fuck like this since I fucked with a drafthorse! Awwww!”

“Wait, when was that?” Mason asks curiously.

“He was my ex. Five years ago. This is so much better than him though!”

“I thought you said your ex was a horse’s ass.”

“HE WAS!” Joe moans out as Mason incidentally presses his hidden prostate.

“Oh so when you – ohhhhh now it makes sense – WHOA!” Mason buckes again as Joe’s big plush ass attempts to suck him in again. “Whoa! Hahah! Woo! Hahahah, wow babe! Hahaha” Mason laughs as he holds onto those shoulders – that butt is actually fucking ITSELF with the toy!

Mason wobbles and tries to get a good purchase as his pelvis is pulled, **** back, and then delves back down. “Fuck, how are you doing this?? Hahah!”

“Ghhh! HOoohhh! NNHHhhh!” Joe’s massive asscheeks flex and clench as he forces that strap-on up and down.

“J-Joe! Ahh! Wait!” Mason kicks about as he tries to hang on.

“Oh sorry, babe.” Joe says over his shoulder. After the pause, Mason gasps as he slides down until his front snugs between Joe’s buttcheeks “MMHH!”

“This is getting hard to stay on.” Mason says as he rocks his hips and rolls into those very soft fluffy buns.

“GHHHH! Hoo, hoo, HOO!” Joe ooks and squirms as his anus gets filled up with solid cock. “I didn’t think it was possible, but I think I’m in fucking HEAT” He growls out as his hams begin to flex and swallow/push the XXL pole up his ass again.

“J-Joe, wait-”

“I’m sorry, Mason, I gotta do this.” Joe then pushes his hand-like feet onto the floor and undulates his beefy round body somewhat.

“A-Ah! Wait! J-Joe!” Mason feels himself topple over – with the giant strap-on still secured around his waist and thighs and still half-way lodged up Joe’s ass. The weregorilla then stoops down and slides the rest of the cock up his deep hole and his engorged butt sits right on top of Mason!

“Oh FUCK yes!!!” Joe howls out as he feels every foot of manhood up his rear.

“Fuck, this IS hot” Mason says as he gazes over Joe’s giant chubby landscape of a back. His dick edges inside of the toy as Joe lifts his rotund form up and slides down.

“Hohhh! Hohhh! Hohhh! HooHHH!” Joe ooks and huffs loudly as all four of his fists root to the floor and he rolls his hips up and down, the fake hyper cock schlorping outloud with each rise and fall of the monkey-man. In front of him, his balls flop and fly up and down while his fat meat twitches around in the air, very much rigid and hard as a tree.

“Hurrbhrhrhh! Hhrrhhbbhh!”

“Uh! Uh! UH! UMMF! UHH! NNHH! OHH!” Mason’s body bounds and jumbles each time those bouncey buttcheeks bear down on him. His hands grab for the floor or a nightstand leg to brace himself for the alternating impact of each thrust. He grunts and huffs hard as Joe’s muscular body ripples with his strength and energy. “F-Fuck! Fuck! FUCK!” He grimaces harshly as he feels his orgasm push up and spurt out of him!

“GGHHH! FFOOoohh!” Mason tenses and seethes as his spent member gets attacked by the membrane of the sleeve within.

“HOO! HOOH! HOOH HOOH! HOOOHHHHHH!” Joe STOMPS his giant ass down on his lover and arches his back and expands his gut before him before his own dick starts erupting! “HOOOHH! AAAAWWAAHHHH!” His fists start SLAMMING into his manboobs dramatically while his cock paints the window across the room. “Haawwwoooo… Whew… Hoh… Wuh… Wow…”

“J-Joe! Please!” Mason whiens as he slaps that massive rump while he writhes wildly. “G-Get off! Please!”

“Oh shit, Mason,” Joe loosens his puckerhole and stands up to let that enormous dildo out of his hole. Mason is already unbuckling the straps and yanks it off before he curls to the side and tucks his arms between his legs. “Oh fuck, Mason, are you okay???”

“Y-Yeah, I’m fine! Ehhggh!” He grimaces and lets his penis breathe. “My dick is just… So fucking sensitive right now… I came a few minutes ago, and it was stuck in the dildo.”

“Aw no… Oh fuck… Can I-”

“Don’t touch it.” Mason grimaces before he gets up. He huffs and gives a weak smile at his boyfriend.

“I love yooouu~” Joe says with an awkward shrug.

“I love you too.” Mason chuckles before he gives a kiss to his monkey man.

The two of them head to bed, with the enormous gorilla going first and settling down before Mason crawls in. He blushes as he feels the enormous arm dig under him and pull him in close. “Hoohhh…” He gives a small moan as he’s pressed into thar perfectly sphere-shaped blob of a gut and next to that smooth mighty pec. “My gosh…” He mumbles as he rubs that big dark grey flan and feeling the firm, hot fur behind him. He doesn’t even need the blanket. He can just snuggle close to him and have all of that heat bundle him up…

Around 8AM, the bedroom is lit by the morning sun. Once again, Joe is back to his normal self – fair skin, modest chub, play across his torso with body hair, and half a foot shorter than Mason.

He slowly wakes up to feel Mason’s arm draped over him like a teddy bear. Joe smiles as he looks to his lover and gives him a gentle kiss on the forehead before carefully shifting out of bed, and walking buck naked to the bathroom.

He takes his usual cocktail of pills to help treat his body from post-transformation side-effects, and takes a minute to brush his teeth and gargle a mouthful of Listerine. Once in the shower, Joe takes his pad and covers it with pomegranate wash and starts to scrub his body with fruity pink suds.

CLINK

“Hm?” He turns and smiles as he sees Mason come on in “There you are, babe.”

“Heeey.” Mason smiles as the two of them share a kiss on the mouth. He hugs him and rubs his abs onto Joe’s well rounded gut. He reaches down and playfully gropes both cheeks while their soft flaccid dongs nuzzle each other lovingly. “How’re you feeling, monkeybutt?”

“Feeling great.” Joe answers calmly. “No headache, not too sore, only a little bit dizzy. The medicine’s in full swing.”

“Mmmhh good.” Mason says as he takes the pad just as Joe turns around and starts scrubbing his backside. “So… I’ve been thinking.”

“Huh?” Joe looks over his shoulder as Mason digs the scrub pad into his rump and scrub his balls.

“About what you said last night – going in for that program to be able to change whenever you want.”

“Oh?” Joe turns back around to let the shower rinse his back.

“And… I changed my mind.” Mason says a bit hesitantly.

“Wha… You’re…You want me to do it?” Joe blinks, “Babe, I was only kidding last night.”

“I know you were, and I was serious about what I said. But… Since we’re planning on moving in a couple of months to that bigger place, it almost feels right to do it. Besides…” Mason grins and hugs Joe close to rub his pecs with those moobs “It was really hot getting to see you transform twice in a row.”

“I mean… I was hot…” Joe says as he takes the scrub pad and washes Mason’s front “But as you said: it’s risky. Once I start, I can’t stop until it’s complete, and it’s going to take a lot of physical therapy and pills and regular treatments. And if I skip out on ANY of it, it could seriously screw with me.”

“I know…” Mason says “And it’s your decision. I just thought it would be sexy and…” Mason sighs and continues “I’m going to level with you. There’s been some rumors about the healthcare policies changing.”

“What?”

“When I went to get your medicine yesterday from the clinic, they told me co-pays and prescriptions might be getting dicey. They even gave me a pamphlet about weres getting the procedures done. I asked around, and they told me that if you succeed with the treatments, not only can you change whenever you want to – with the exception of a full moon – but we’ll also get to stop with the pills and injections, and it will loosen up our healthcare by a lot.”

Joe just smirks and plays with Mason’s balls, seeing Mason is already sporting a chubby “Why do I get the feeling you’ve done a lot of research on this beforehand?”

“You know why.” Mason nips at his nose and turns around to let Joe scrub his back. While Joe gets the suds into Mason’s nooks and crannies, “Look. All romantics aside, having you go in for this treatment might actually be more affordable for us in the long run.”

“I know… I hear you…” Joe says as he hugs Mason from behind and spoons him while the shower rinses them both. “I have been thinking about this for a long time. To be honest, I even wanted to surprise you for our anniversary by transforming on the spot. But I didn’t think you’d be all up for it…”

“To be honest, I probably wouldn’t. I meant what I said last night.” Mason turns around and kisses Joe’s lips “I love you, human or ape. And the full moons are special. But if the healthcare are going to get bitchy from under us and it makes things easier, it might be time to make the call.”

“Yeah… And besides…” Joe nods “I’ve heard it’s less painful when it’s done. Like, my bones and muscles won’t feel like they’re getting butchered every time I change…” Joe puts a hand on his round stomach and looks back up “I wanna be able to not hurt…”

“And you know I’m going to be there right beside you, right?” Mason says as he interlaces his fingers. “We’ll do this together.”

Joe smiles and goes on his tippy-toes and goes for a deep kiss. Mason laps back and rolls his tongue in passionately as they rub and grope each other.
