Michael watched as Ashley, Natalie and Meredith cleaned themselves of his spunk, wiping handfuls off their curves and licking their hands clean of it
"That was great Michael, do you think they want more?" Ms. O'Neil whispered into his ear, one hand rubbing his immense shaft and the other around his shoulders, her face next to his and her soft body pressed against him.
"I-- I don't know..." he responded, watching the girls, who only a couple days ago had all ben slim, shake and jiggle their nude bodies in front of him, the involuntary teasing keeping him at full erection.
"I think they do, why don't you rub that huge cock of yours and make them bigger, hm?"
"Wh-Why are you doing this, Ms. O'Neil?" Michael asked, looking up at her as his hands automatically worked his cock
"You can call me April, and I'm doing this because I want to. Why else does anyone do anything?" she kisses his cheek as she leans back on the couch, looking over the girls expectantly.
"What is that supp--" Michael starts to respond, but is cut short by his own orgasm.
"Now Michael," April smiled, watching the girls swell ever fatter, "I don't need you to think, I need you to just work that cock of yours and make every girl you think about big, fat, and curvy." she continued, cuddling his head between her breasts as his hands stayed on his cock. "So, tell me about some women you know that would look better bigger." she instructed.
"Uh, there's, uh, Casey. She actually told me the other day she wanted to gain weight so she could get bigger boobs..." Michael sheepishly said, red in the face. He grunted as he came, knowing that it meant Casey was going to be getting those boobs she wanted.
"Very good, Michael," April encouraged him, fondling his balls, "Does it excite you, knowing how fat she'll be getting because of you?"
"Y-yes!" Michael responded quickly. The very knowledge that Casey would be growing the very tits she wanted, and that she would be wanting to use them to pleasure him made Michael quickly cum again.
"And she'll certainly be very busty next time you see her now. All because of that big dick you can't keep your hands off of." April giggled. Michael struggled to half-heartedly smile back at her. He looked down at his groin, shocked at how large his genitals had grown. Even angled out, his cockhead was level with his eyes, and he shivered at how his balls covered his lap. He looked up at April to say something, but he didn't see her, he just felt her tits rest against each side of his head. "There certainly must be others you want fattened up, right, Michael?" she teased
"Yes, there's Isabella." Michael said almost involuntarily, "She's already huge. Her hips are twice as wide as her shoulders, thighs thicker than my waist, an ass so big I wonder how it's real, bigger still than Natalie is now--" Michael said quickly before cumming. Everyone so far had been skinny when it started, he wondered how it would effect someone already so fat. His thoughts about her ripping from leggings or jeans and bursting tops or breaking furniture just from his first orgasm quickly led to a second, then a third.
The sound of his cum falling to the floor aroused him, he couldn't stop, even when he was trying and the teasing just made it even easier to jerk off. He gasped as April's tits swelled on either side of his head as more cum spilled out onto the floor.
"Whoa there, Michael!" April hefted her boobs up, "I need you to focus on the other girls, not me." she giggled a little nervously. "And the girls here look to be as full as they can get." Michael looked past his cock as Natalie, Meredith, and Ashley slept on the floor, their bellies swollen with as much cum as they could hold.
