As they fucked and came and fucked and came, both Eileen and Ty began to exhaust themselves of everything. Barely even conscious, the two eventually separated, drenched with sweat and panting, and both sat taking a moment to bask in the afterglow of young and hormonally overdriven love.
At last, Eileen raised her head and tried to stand, collapsing into a heap and moaning in pain by the toilet. "I can't walk." She said blearily. "You killed me."
"This... this isn't going to help, then." Ty grinned, willing her to age forward to 15, like him.
Eileen let out a sudden scream, all of her nerves and senses overloaded with lust, and groaned in wrenching agony as she pushed and grew into her 15 year old body, becoming a curvy and tightly slim young lady with large D cups. Her dark skin glistened with hot sweat and she fell forward gasping as the changes released her.
"Oh..." She whispered. "Oh, no more for now. I'm... I'm... I've got nothing left."
"All right." Ty said, gently pulling her close and cradling her in his lap.
They sat like that in the bathroom for some time before Ty and Eileen fell asleep that way.
