It hits Jenny, at level 5

As John sits on the floor trying to contain the feelings running rampant inside him, the pink beam of light shoots through the room. It crackles in the air mischievously before hitting its target. He manages to open his eyes to see his sister rolling over on the couch as the transformative energy invades her body.

She gasps for air and arches her back, giving John a perfect view of her rapidly enlarging breasts. Chloe giggles, sitting on the stairs with one of her manicured nails teasing her clit. Both of the younger siblings can't take their eyes off the sight of their usual uptight and proper sibling look more and more like a pornstar.

Jenny moans, running her hands through her hair while it lightens in color, until its a bright platinum blonde. Small giggles start to leave her mouth, her brain changing to match her new form. John watches in fear, and a bit of intrigue as his sister's shirt rips open, freeing her bouncing rack.

The light finally begins to fade, leaving Jenny staring up at the ceiling panting. Her wasp-like waist and fat ass make her current clothes fit nothing like they should. Her eyes glow slightly with a bright pink color, signifying the bimbo energy still inside her.

Chloe moans loudly from the stairs, seemingly bringing herself to orgasm at the sight. Her fingers deep inside herself she stamps her feet on the ground, unable to contain her excitement as she shakes and shudders.

His head rapidly turning between the two, John seems to be the only one not completely enamored by their bimbo selves. Chloe has already succumbed fully to the ray's effects, and by the looks of it Jenny doesn't seem too far behind. She slowly slips her hand into her panties, a devious smile on her face. *giggle* "Chloe! Like, you little minx! Think you can like, outdo your older sister?" Her voice has raised a few octaves, and has gained a new sultry demeanor. John watches Jenny take Chloe's orgasm as a form of challenge, her bimbofied self trying to catch up.

Soon, loud moans fill the room. Both the girls masturbating while staring at eachother. They try to look as whorish as possible, giggling when they change position to give the other an even more depraved view of themselves.

On the floor between them, John seems invisible. He fears that any movement will alert them to the fact that he's still in the room with them. While he's scared of what's to come, he can't deny the erection in his pants. He's been shot by the bimbo ray as well, and while he's still technically male, his small breasts yearn to be touched. He breathes quietly, trying to contain his artificially boosted libido while coming up with a plan.

Soon, the girls cum again in sync with eachother, and John sees his chance. He quickly stands, once again wincing at the sensitivity of his nipples against his shirt. He scans the room and with a **** confidence, runs after his goal...
