Cum-inflation

As you relax from having the best sex and orgasm ever, Alexis grabs your arms and shoves her self deeper inside. Her thrusts continue, prompting you to ask "Still not finished, huh?" Not that you mind though.

"Yeah, I need to cum a minimum of 30 times before I'm satisfied." Alexis says still intently thrusting her hips, her massive rack jiggling under you, making your cock erect again.

Load after load of sperm is dumped into you, your belly taking up most of the livingroom. In your bliss you cry out "More! Make me huge! More cum!"

"You'll get all of it babe, don't worry your tight ass." Alexis cooes.

After an hour of fucking you feel Alexis's cock go soft. She slides out from behind you. Your over-inflated gut is pressing against the walls of the room. "Ahh, much better." She says, her tits laying atop a section of your belly. "That was some good work there lover boy." Alexis teases you "Maybe I'll give you even more later as reward."

"But I want more now." You pout. Alexis assures you that waiting is beneficial to both of you. You ask how.

"Well, for one we need some more space. Also once you're done shrinking down the side effects of my cum will start to set in."

"What side effects?" You ask, your curiosity mounting.

Alexis just smiles and pats her impossibly big chest saying, “You'll see babe." She has you suckling from her tits. "You’ll need your energy up for later." Alexis muses as you suck on her nipples. The warm milk makes you feel drowzy. You fall asleep dreaming of the next fuck session with Alexis. The changes take hold as you slumber.
