Someone about to get a math lesson!

“You sure you can handle that math?” Felicity asks as her balls rest on the floor. She is standing in front of you with her leaky dick in your cleavage, spreading it wider.

“If I can fit you in, the rest is cake,” you brag.

“You don’t care how loose your butt gets, do you? It’s going to be *really* loose after this,” Dee warns you.

“Of course I care. I *want* it loose, silly! Hopefully Felicity can really mess me up down there...more than you two already did, of course!”

“You are going to get your wish, baby. Felicity, make sure you pull his anal slit down between his legs once you feel your head get lodged in there good. The gap between his hips won’t flex so you need to go around it. He has been stretched nearly to his belly button before, so you should be able to bottom out once you get the angle right.”

“By me, you mean you, right? I’m not going to be able to aim that thing once it’s that big and heavy!” Felicity eyes her cock that has stopped lengthening but has girth beyond the width of your torso. Your breasts hang off to either side of you.

“Looks like my nipples are ready for action, too. If you ladies want to help me get myself positioned, I’m ready,” you announce.

You are quickly lifted from your feet by your legs by the twins onto the widening pole of Felicity. With a nod to confirm she has her mushroom lodged in you, you are pulled back away from her. Your hole is being pulled to your front through the gap in your legs. You feel your hole being pulled outwards and down, away from your hip bones, and your legs are knocked to the sides and then pulled slowly into a split as the girth of her dick moves past the space between your legs. Your dick and balls hang uselessly from your grotesquely stretched and bulging abdomen as Felicity smiles at your predicament, her own dominant penis approaching your goal as you see your flesh stretch out to your sides like a condom.

“Wow, you are so big,” you breathe as your hands feel the seal between you, that used to be your anal slit, is getting thinner.

“This is such a trip! It’s like you are a human condom!”

“I don’t think I’ve spilled a drop yet, actually,” you muse. “Don’t think I can now, either!”

“I think we are there, sweetie,” Dee notes.

“Yup, she’s as wide as your hips, baby! You did it!” Jay cheers.

“You are so tight,” Felicity moans.

Not to be left out, Felicity watches as your breasts are manhandled into position to service the other four cocks. With a wet ‘schlup’, one disappears into each of your leaking nips. The second one follows more easily than you had expected. Soon, your voluminous breasts are bouncing a couple of feet off their crotches as their dicks loosen up your ducts. Felicity is in awe of her own appendage stretching your midsection now about 10inches beyond your widest point.

“This doesn’t hurt?!?” Felicity asks incredulously.

“We trained him well,” the twins reply.

“I’ve had literal tons of cum in there,” you giggle femininely, to your surprise. “L-looks like my voice...”

“Your adams apple just kind of shrank away,” Felicity voices her observation.

“Didn’t need it anyways,” you reply in your new higher octave. “So when does it stop growing? When you cum?”

“About that...” Felicity begins, “You are so tight, like a condom like you said, that I’m not getting any friction. You are like a literal condom, with a package hanging off the front,” she adds with a giggle.

“Not a problem! You said the biggest you got was twice this size?”
