Ultraboy can't resist!

Ultramom pounded on the wall of the cell, begging Doctor Bluder to release them before something bad happened. Doctor Bluder just smirked and crossed her arms, smiling as she saw Ultramom arch her back as she continued hammering on the wall. Unfortunately for Ultramom, the combined aphrodisiac and fertility **** had worked their magic on Ultraboy.

Ultramom grunted as she felt her son ram his big fuckstick in her to the hilt, she closed her eyes and shuddered as she felt her body respond in a way she hadn't felt for a while. Doctor Bluder laughed as her plan took effect on the two heroes, she actually felt herself getting wet at the sight of Ultraboy's sexy body and big cock.

"If he's got good stamina, I might have him breed with me...."

Her attention was shook when she heard Ultramom whimpering at Ultraboy's balls slapping against her clit, making her pussy cream even more over his cock. Ultraboy was almost animal-like in his slamming of his helpless mothers twat. Ultramom was starting to drool as her body started to get exhausted from the amount of climaxes that her young son was putting her through. What she hadn't told her son was that even before the evil doctors fertility ****, she was already pretty fertile.
