Why leave home? (Gwen)

John stared at the futuristic raygun in his trembling hands, his mind racing with the endless possibilities. He had already tested its miraculous powers by swapping his dull, unremarkable eyes for his bombshell mother Athena's more vibrant, alluring peepers. The fact that she didn't even bat an eyelash at the sudden change proved the Swapinator's reality-altering abilities were no joke.

His gaze drifted up to the mirror, drinking in his new exotic eyes. They gave his nerdy face a subtle sultriness that sent a jolt of confidence through the perpetual virgin's scrawny frame. If a simple eye swap could have such an arousing effect, he could only imagine how mind-blowing it would feel to acquire even more of his mother's or sister's ridiculously stacked assets!

Gwen's lascivious figure sprang to mind first, the image of her plump, fertile hips and thick, juicy thighs seared into his psyche. Her tits were definitely the main event though - those massive, doughy 34D melons straining against her tight tops, begging to be unleashed and worshipped. John felt his dick twitch just picturing himself with that level of breasty, top-heavy thickness.

He crept out into the hallway. Gwen’s door was creaked open, “Perfect!” He aimed the Swapinator at his flat, boyish chest ***ZAP*** Next, he zapped his buxom twin sister through the bedroom door frame, catching her in a state of undress as she changed clothes. Gwen's luscious, fertile form was on full display, those big, beautiful breasts swaying hypnotically with her movements.

"Gwen's huge tits," John thought, mouth agape as he drank in the glorious sight. He screamed in his own head, “I want Gwen's huge, bouncy tits!"

He yanked the trigger, and suddenly a bizarre sensation overtook his upper body. His chest felt unbearably tight, like his skin was stretching past its limits. The young stud gasped as he watched, seeing two large, womanly mounds blossom from his flat chest in an instant! Gwen's doughy, D-cup breasts were now his, the hefty twin melons settling into place with a tantalizing jiggle.

"Oh fuck..." John groaned, cupping the brand new tits that were now HIS to play with. They were unbelievably soft yet carried a delicious weight in his hands, making his cock swell just from the sensation. He gave them an experimental bounce, mesmerized by the hypnotic jiggle and sway of the fleshy fat bags.

The once-scrawny dweeb felt an intoxicating surge of power and confidence now that he had a nice, thick set of funbags to call his own. He could hardly wait to see what other bountiful curves the Swapinator could bless his inferior male form with!
