Reverse

While Elaine has wrapped her arms around you, you still have the ray gun. You move the know to "Reverse" and shoot her.

Elaine reverts back to her former self. She screams. Her hair, tits, ass and pussy are back to normal proportions. She pushes you off and screams, "What the fuck?"

Marty jumps at you and you instinctively shoot him with the ray gun.

He lands on top of you and smiles.

"Well, lookie what we have here," Marty says and starts sucking your dick.

Reverse reversed his mind and now Marty is gay.
