Horny too.

"Master, unfortunately I cannot fill you at the moment," Red tells you as you still stand in your previous position.
"Such a shame, that's so hot!"
"It was so big, just big enough," you tell Amy.
"For now," Amy tells you. "That wasn't even as big as her thigh."
Red moves up behind you, her cock it's meager foot long but almost as thick as Blue's.
"Can you keep from cumming for longer?" You thrust your cock at Blue's mouth a few times until she opens it and you plunge into her. She sucks it like a lollipop.
"Probably not," she replies. "I may cum almost immediately, in fact." She gently guides her cock between your cheeks, illiciting a sigh from you both.
Red slides up against you fully, pressing her breasts into your back.
"I can't see anything," Amy alerts you. "You need to change position."
"Ah, I'm just fine here," you answer.
"Sandwiched between two shemale demonesses. No fair." She pouts.
"You just have cock-envy. You are coming along well, though. Come here, and cum here," you tell her as you pull her to you and point at your open mouth.
"Oh, you want to suck me off?" She allows you to guide her to your awaiting orifice. It must be a couple of inches now. Still small for a cock, but bigger than a girl normally has. It still feels great to have between your lips. She leans down and her breasts surround either side of your head. They must be more than ten times her original size. You are catching up, though, much to your surprise. You figure yourself at like a D cup, and she must be only a large DD.
Not even thinking to hold back during your thoughts, you cum into Blue's mouth. Your ass clamps down hard and you suck hard at Amy's cock inadvertently, causing them both to hold you tight as they shoot cum in both ends of you.
Blue then disappears, returned to doll form.
"Already?" Amy picks her doll off of the couch.
"You need to show her a good time, and she will stay longer," you tell her. While they both move to sit on the couch, you stand there in the same position.
"That's a good position to keep," Amy agrees.
"We are both drained, Master," Red tells you. She rubs your leg. "Come sit," she pats her lap.
"Fine," you say, disappointed, and plop down on her.
"Careful of the goods, Master," Red tells you as she adjusts her package to place her balls between her legs. You rub your butt against her limp and sticky cock, hoping to arouse her. "Master, haven't you had enough cock for now?" Red asks you.
"I just need something in my butt. Please?" You can feel her cock stiffening.
"Very well, Master. Stand." You stand and she holds her pole straight up. "Sit on it." You lower yourself quickly, and on the way down your butt simply gobbles up her cock.
"Isn't that better? It is for me," you tell her.
"Yes, it is. You do need to take a rest, Master. These urges will keep building the longer you go without sleep. Soon you will need both holes filled nonstop with a mouth for your cock and each tit."
"I have plenty of what I need," you look to both Amy and Red.
"There's nothing wrong with wanting cock, Master, but going insane without it is another matter. Get some sleep after I return to my doll form."
"I'll make sure he does," Amy pledges, as she climbs in your lap. She alternately puts your cock in her pussy and ass. "Which do you like better?"
"Both," you tell her.
"You have to pick one," she retorts.
"Why?"
"I have to know which to stick it in, silly."
"I like how you are doing it now."
"I can't keep doing it like this!"
"You can if you want to!"
"Amy I can't wait until your cock is larger than mine, so you can be here and you can have a cock for each hole," Red interrupts. "You are so controlling."
"My place, my rules," Amy states simply.
"She will keep hanging onto that," you tell Red.
"Yes, Master."
"Be lucky I don't **** my rule," Amy tells you haughtily.
You then fall suddenly to the couch. You dig the Red doll out from under you.
"All alone," Amy tells you. "I'm so hungry."
"Me too, you tell her."
Both of you get up, but she stops you before the kitchen.
"Get some clothes on first." She heads into another room and comes back with an armful of clothes. "Yours, yours, mine, mine..." she drones on as she separates them.
You slide on the thong she gives you. Perfect fit with room to grow, and a high-fitting waistband that sits on top of your hips which are now protruding far enough to allow it to. Next is a bra made of thin material. Looking down, you see your nipples are looking quite distended. You slide on the bra and find that it also fits well, and pushes your breasts out, up and together. Almost feels like they will pop out. Stretch pants for the bottom. "I couldn't find pants with a large enough butt," she adds. Finally an equally stretchy shirt with a neckline that plunges so low your bra is visible. Amy is wearing just another bikini.
"You didn't get anything else?"
"Sure I did, but I look so good in these now, since I have big boobs," she smiles. "You look good in those, too," she licks her lips.
"I look like a girl," you tell her.
"If the tits fit..." she trails off, looking you over. You put your hands on your hips and let her ogle you. She hefts and feels you in various places. "We can eat now." She leads the way to the fridge. She pulls out some snacks first and you both eat them as she starts cooking other food. You watch her body jiggle and realize she looks very pregnant now. You do too, just not as much. You pat your belly.
Looking back up, you see her ass swaying slowly as she cooks. She is sweating from the heat of the oven and stove. Each time she finishes one plate of something, she starts another immediately.
"Hot?" Amy asks you. "Sweat is running between your tits."
"A little," you answer as you wipe at the sweat pooling in your cleavage.
"And your high beams are on," she giggles.
"Yeah, they are big," you tell her, looking at the thick two inch protrusions coming from the center of each breast. "These stretchy fabrics don't hide much." You grab a hold of each nipple and roll it a bit in your fingers. That's not too bad.
"Stop playing with yourself," she tells you.
"Tantalized?"
"Sure am," she says as she walks up to you and sits on the table in front of you. She sits there, waiting. "This is my blowjob position," she states impatiently.
"Not for long. It's getting covered by your middle."
"I'm sure it will grow long enough to keep sticking out." She picks up a bowl of noodles and starts eating it, eyeing you.
"Fine," you say before you slurp her up. It is barely more than a large clitoris still. You just roll her around between your lips until she squirts a minute later or so. It is barely worth swallowing, due to the small quantity.
She puts her empty bowl down. "That feels better. I don't know how you guys walk around all day without constant servicing." She hops up and returns to cooking.
"Do you always cum from your penis now? Even when your pussy orgasms?"
"I haven't tried yet," she says thoughtfully. She raises one leg and puts it onto the counter and then spreads her other leg to widen her stance before thrusting her ass out. "Have at it. Don't blame me for getting cum in the food if I shoot."
You get up after finishing your last bite of a sandwich and quickly move behind her, pulling down the waistband of your pants in front as you go.
"I wouldn't mind cum in my food."
"There will be more once my balls get to be nice big cum factories. It will be more than just a few drops then. You think you can handle that? Cum at every meal?"
"I hope so, because I think you are going to do it anyways," you tell her as you push your dick into her pussy. You press up against her back.
"You gave me the idea, just so you know. No backsies! I love the feeling of tits on my back. Makes my cock hard."
"Like it's gonna cum?"
"I still feel a girlgasm building too. I may in fact cum!" Amy seems excited by the prospect. She shifts her position suddenly, leaning over the stove. "Ahhh, it's happening! I'm cumming in the food! You are gonna eat it!" You feel her pussy working in orgasm at the same time. She then gets very heavy, losing her strength. You hold your cock inside of her and hold her leg on the counter. She slumps forward a bit. She doesn't touch the stove. You reach around and grasp her cock and rub it. "Too tired," she whispers.
"Your cock is still hard."
"It is? Oh OK then," she says sleepily. "But your cock in my pussy?"
"Still hard too!"
"Well if we aren't just a couple of horny shemales."
You keep gently moving your dick in her as you rub her cock. She cums once from her cock into the food, but her pussy didn't contract. So one will trigger the other but it doesn't work the other way. You start fucking her pussy again normally while keeping her cock occupied. She cums twice more from her cock before you manage to bring her pussy to orgasm which causes her cock to cum again. She goes completely limp then. Her weight pushes you down as you sink to the floor with her, one hand on her cock and the other on her ass.
"So sleepy." With your cock still buried in her pussy, she turns toward you. Your bellies prevent you from meeting head on, so she  bends, putting hers to one side. She then lays her head in your cleavage, with one hand on each breast. "You can keep going," she whispers.
You bounce her ass off of your crotch and rub her dick some more. You see Amy's right breast that is resting on your belly has lost its part of her bikini. You stare at it as you fuck her. It ripples pleasently.
You must have been extremely exhausted, because Amy cums again before you even get near cumming yourself. She splashes her tiny load on the underside of your belly. She can do that a lot! Maybe it's just because it's new? She only cums once more from her cock and when she cums again with both, you shoot your load into her pussy.
Exhausted, you fall asleep right there.
