To three horny shemales.

"What a day," Amy says, rubbing her middle. "How wide is he gaping? Is it enough?"
"Let's see," Red says as she explores between your cheeks. You bend over so she has better access, and put your mouth on the end of the blue cock jutting out at you. It's quite a bit larger than you remembered. Her arousal from before, perhaps? You use your fingers to spread your lips around the head. It really is massive. You manage to have your lips catch under the flaring head. It is partly in your throat and fills your mouth completely, pushing out your cheeks so that there's no doubt as to what's in there.
"Look at that, you never get bored, do you?" Amy observes your antics.
You find Blue's hands with yours and put them on the back of your head. Blue pulls on your head, forcing her cock into your throat. You feel your neck and can feel the cockhead shape bulging out your skin. You feel like it's your duty to swallow this whole thing. You know Amy will expect deep-throating no matter how huge she gets in the third leg area. Imagine one up your ass, one down your throat. You know that's a possibility with your demon offspring on the way. You wonder how big Amy's penis will actually get. You both show no signs of slowing your growth in your respective most-noticible areas; your butt and boobs and Amy's cock and balls. It's great that you both fit so well. Amy wants places to stick her ever-growing log, and you keep up with places to put it. You will both be ruined for anyone but each other. Nobody else could deal with Amy's cock, and nobody would be able to fill your various fuckable places the way she could. Red has her legs in you, stretching you to see how wide you are. You look up at Blue with a nod to your behind.
"Wide enough? You seem to have your legs splayed wide," Blue queries.
"Ah, yes, plenty wide. In fact, more than is needed by several inches. You won't have to work on this anymore, Master."
"Really? I think that's too bad," Amy pouts.
"But Mistress, now we can work your ass open just as wide!"
Amy looks at the big smile on her face. She puts her hands on her butt cheeks. "I'm not ready yet!" Amy watches you slowly swallow Blue's penis. "That's amazing...I want to see the cum."
"Yes, Mistress, I was holding back."
You feel jets of hot liquid shoot against your throat.
"I can see where it hits on your skin...it pushes it out!" Amy bounces as she watches.
Red produces a watermelon. "This isn't a suppository, Master!" You shrug. You can't respond at the moment. Once she finishes cumming in your throat, Blue pulls out. You take a huge breath of air then lick your lips.
"Yummy," you smile.
"Was it? So are you full then?"
"I'm never too full for shemale cum! C'mere!"
You rear back on your haunches, causing you to slide down Red's body as she scrambles to get out before you do. She smiles sheepishly.
"Master I am in you."
"So? Just hang out 'til I'm done here. It's not like you have a huge belly weighing me down."
You feel a splash of wetness as a huge cock smacks your face as Amy sits on Blue's rack. Wow, that's even bigger than what Blue just fed to you! She is keeping pace with you. She smiles proudly at your reaction.
"Big, huh? Yup, that's one fine girl cock. Look at these nuts, too. Gonna have a pair swinging up top and between my legs," she compares her tits and balls.
"Tits and ass is my turf. Just wait until mine are thiiiis big!" You stretch your arms out for emphasis.
"Hehe, then that might give me some good fuckable cleavage!"
"Yeah, I hope so," you say as you start licking her. Then you stretch your lips around her mushroom head and catch them on the underside. Definately bigger...you can't even begin to manage a smile. Amy doesn't waste time pushing into you. You grab at her balls, as she wraps her feet around the back of your head and locks her ankles. After moving her hands to grab her shins behind your head, her nipples dangle in front of your eyes. Amy's swollen sack rests between Blue's knockers and your own milk factories. You take a big sniff of air into your nose and start swallowing motions so Amy knows you are ready for her. She pulls with all the might of her arms and even more powerful legs. Her cock anticlimatically rides the muscle ripple of your swallowing motion down your throat, easy as the anal cream pie you love these girls to make for you up your ass. With your nose pressed into her belly button, you look up but only see the bottoms of her heaving busoms. Not heaving enough to suggest impending orgasm, however.
