Mom gets a call from her sister

A few weeks after your legendary house party, you wake up with a hard-on. That's a less common occurrence these days, since you often go to sleep with Mom's lips wrapped around your cock... But last night was Dad's monthly turn with her.

It's one of the concessions you give him, in exchange for allowing you and Cassidy to treat your mother like a piece of meat. Once a month, you use a bed sheet to set up a glory hole in his bedroom. Then you set Mom up behind it, with a pillow to kneel on and enough junk food to last until morning. That way Dad can go to town on her mouth as many times as he likes, without having to look at her fat body.

Mom thinks it's you or your brother behind the curtain, of course; given your father's condition, she'd never willingly drink his seed. She's figured it out a couple of times, when Dad's groans got too loud and too distinct... But in both cases, she forgot all about it by the time next month's appointment rolled around.

The routine keeps Dad happy, but this morning it's saddled you with a serious case of morning wood... Totally unacceptable, now that you've grown accustomed to near-instant relief. Throwing on a T-shirt, you tromp down the stairs with your dick in hand.

"Heeey, Rachel!" You hear your mother talking loudly in the living room; she sounds excited. "I can see you. Can you see me?"

Another voice replies, a little muffled: "Jenna! I... I see you. Um, you look so... Different. " You recognize it as your aunt Rachel, who you haven't seen in almost a decade. She lives in England, and she never got along well with your mother. Any time you and Cassidy would get into a fight as kids, she'd compare you to her and Rachel.

"I do? I guess I changed my hair," your mother says. As you enter the room, you can see that she's sitting on the leather recliner with her tablet propped up on the coffee table. She's just starting a video call with her older sister, while chowing down on a package of cookies. "Anyway, how are yooou? It's been ages!"

"I'm... Uh..." Your aunt looks flustered; she must be shaken by the extra pounds that her sister's put on. You're not exactly sure how much Mom has gained this year, since actually weighing her might break through her dumb haze and freak her out... But it's certainly enough to be noticeable, even with only her head and chest in view: her face is much plumper, and her breasts have doubled in size. They're currently wrapped in a bright floral dress, with plenty of cleavage spilling over the top.

"I'm so-so, Jen," Rachel continues. "I don't know how it is there, but H1N1 is getting pretty serious in London. Too many women, not enough medicine. Harold helps me when he can, but..." She sighs. "I'm afraid he's being tempted on the subway. Everyone's dressing shamelessly, all those pretty girls... Even I have to walk the streets sometimes, just to keep up! A respectable, married woman!"

"That sounds hard," your mother replies, scarfing down another cookie as her sister continues ranting.

"If you ask me, everyone should stick with their own man. Those... Those bimbos are stealing my husband's loads, so I'm **** to go out and proposition their husbands... It's so inefficient, self-defeating, pointless--"

Just then, Mom glances up and sees you. "Oh, look! Marcus is here," she says happily, relieved to have a break from listening to her sister; she's probably using too many big words. "Say hello!"

You step behind the recliner and into the frame, cock bouncing just above your mother's shoulder. "Good morning."

"Agh!" Your aunt is stunned for a moment, her eyes flitting up and down. "That's... Your son. And his..."

"I know, he's grown so much since the last time you were here," Mom says. She's probably talking about your height, but it takes on a very different meaning as she reaches out and begins stroking your shaft. "He and Cassidy help me sooo much. I have all the medicine I need!" Smiling, she looks up at you. "Are you almost ready to feed me, sweetie?"

"Oh God... I... I can call back," Rachel groans.

"Nonsense, I know how busy you are. We can do both," your mother replies, stroking faster. "How's work? You do... Computer stuff, right?"

"...Yeah," Rachel sighs, rubbing her temple. "It's okay. My office is almost all men... The sexual harassment policy's been thrown out the window, of course, but at least they let me swallow sometimes. It's humiliating, but... It works."

"Mm, totally." Your mother doesn't flinch as you slap the lever on the recliner, letting it fall into a near-prone position. Then you bend her head backwards and straddle her, your balls brushing against her lips as you aim your erection into her cleavage. Reaching down, you grab her heavy breasts and squeeze them around your cockhead. "Mph... How's work?"

"Holy shit..." Rachel shakes her head, too focused on her little sister's humiliation to wonder why she just asked the same question twice in a row. "Do you have to let him do that?"

"Do what? Gmph... Play with me?" You rub your sack all over her face as she talks, enjoying the sensation of her warm breath on your balls. "If I give him whatever he wants, he gets hard faster and cums way more."

"Well... At least you get all the medicine you need at home." Rachel's eyes are on the floor now: even if she were still able to look her sister in the eye, your crotch is in the way. You begin pumping between Mom's breasts, balls sliding across her face with every thrust. It's one hell of a feeling, and the silky sensation of your tip against the inside of her dress isn't bad either... And you were already so horny...

"Uuungh," you growl, shooting a fat load into your mother's cleavage. A dark, shiny stain immediately appears between her breasts, growing by the second as you continue groping and humping her reclined body.

"Jesus, is that--Jenna, he's cumming!"

"Oh, uh... Sorry," you lie half-heartedly, pulling out of Mom's dress and shoving your dripping cockhead into her mouth. "Here, I only wasted a little bit."

"Mmgh--Thanph ooh," your mother mumbles around your shaft, before grabbing your hips and pulling you in deeper. She doesn't seem to notice that your orgasm is finished, and is making every effort to massage your sensitive cock with her throat and tongue.

Even on the other side of the tiny screen, your aunt can tell something's not right. "Jen, I think he already--"

"Oh, Mom, looks like you finished off those cookies," you grunt, pulling out of her desperately-sucking mouth. "Want me to grab you another pack?"

"...Guh... Yes, p-please," your mother replies, as you slap your cockhead against her lips before clambering off. "Isn't he a sweetheart?"

"I... Fuck, Jen, this is..." Your aunt leans forward, head in her hands. "...Shit, is it really getting that dark over there? I mean, things aren't great here either, but..."

"What do you mean?" As you return with the cookies, Mom snatches one and pops the whole thing in her mouth.

"Is that why you're eating? All the stress, the fucking humiliation?"

"I don't know what you're implying," your mother snaps, her mouth full. "My family takes good care of me, and so what if I have a healthy appetite? Marcus says that it's important to eat lots, so that I can meto-boli-size all the medicine they feed me. Gotta have a balanced diet, so..." She trails off, grabbing another cookie.

"That's not... Even if..." Rachel sighs, then looks at you. "Are you little wankers abusing my sister? You didn't think anyone would notice?"

"No... Just didn't think anyone would care." You glance at Mom, but she only seemed to register the "no" part of your comeback. Emboldened, you continue: "You're just jealous that you don't have two young studs to keep you fed."

"That's outrageous! I--"

"That makes sense," Mom cuts in, wiping her mouth. "You always were jealous of my children."

"Jen, you can't possibly be taking his side! He just creamed all over your... Your fat tits, and now he's touching himself while watching you gorge yourself on junk--"

"Rachel!" Your mother looks horrified.

"I think this call is over," you say calmly, before reaching out and turning off the tablet. "Jeez..."

"I'm so sorry about that, Marcus," Mom sighs, nibbling on a third cookie. "My sister's under a lot of stress, but that's no excuse to be rude to my special, hard-working boys. People are so nasty these days... If you want me to stop talking to her, like with my doctor or that busybody Mrs. O'Moore... I would understand."

"It's okay," you reply with a grin. "Just don't put too much stock in what she says. She's obviously delusional." With that you step forward, stroking your glistening cock just inches from her face. "Suck me off again?"

"Already?" She's beaming with pride as she licks her lips. "Of course, sweetheart! Thank you so much!"

The blowjob is long, slow, and truly passionate. This time you let her drink half of your load, watching her eagerly swallow the medicine before pulling out and pumping the rest onto her face.

"Aw, you stopped too early again," Mom says, wiping some cum off her cheek.

"Wait, don't eat that," you reply. "I'll get you some sweetened medicine from the fridge, okay? That raw stuff doesn't taste as good, and it's healthy to leave it on your skin anyway."

"Right, okay!" She waits there patiently as you run to the kitchen, letting your cum dry on her face. When you come back with a tub of icing sugar and a spoon, her proud smile returns. "You're such a good boy... I feel sorry for Rachel. How does she survive without sons like mine?"

"No idea," you laugh, slapping your cock against Mom's cheek one final time before heading back upstairs.
