You really wanna have fun in this room, but first you wanna find out how it affects your sexualities. "Um... before we do anything, can we try something?" you ask him.
"Of course!" he smiles.
"Well, can you quickly turn back into a girl to see if it makes me straight again?" It's such a weird question to say, but you're glad to get him to do it.
"Yeah, no problem babe," he replies softly, and kisses you.
He goes back to the mirror, closes his eyes for a moment to focus, and then wishes. Slowly his body starts to turn feminine again. You see his jawline soften and his crew cut rapidly lengthen, his hair falling to partway down his back. His upper body's muscles thin out and his shoulders narrow again. The nipples atop his toned pecs swell and widen, and soft flesh sprouts around them again. His skin seems to be softer and paler now, and his straight figure turns curvy with wide, feminine hips and a soft butt. The only remaining part of the man your girlfriend had just been was his 7 1/2 inch cock, but that soon started to tug inside him, accompanied by groans and pants of an increasingly higher pitch. His balls also move up inside her, and and you watch as his penis finishes becoming her tiny, firm clit, while her former scrotum sinks into her and a slit opens down the middle.
To your relief, as you looked at her restored feminine form, you felt intense attraction to her. You wish so bad you could tear your clothes off, catch her from behind and plow that cute pussy while cupping her big soft tits. She turns around, and noticing your dreamy smile, says, "Guessing you turned straight again, huh babe?"
"Yeah," you giggle, and she comes up and kisses you. But as her hand reaches for your crotch, you stop her. "Hang on!" you say. "There's something I wanna try."
"Is it something I just tried?" she smirks.
"You could say that," you tease.
You undress, and stand in front of the mirror naked. Concentrating on your body and thinking you want to find out what it's like to be a woman, you feel a weird twinge inside you as your wish is granted. You lose a couple of inches of height, and your reflection changes, your facial structure altering as your stubble vanishes, your cheeks and lips turn slightly puffier and your hair lengthens a bit. The changes move downwards, your larynx turning much less pronounced as your voice turns higher, and your figure adjusts, your shoulders narrowing and hips widening as you turn slimmer. Your muscles turn more lithe and less pronounced, and your hands and feet slightly shrink. Soft C-cup breasts rapidly swell on your flat masculine chest, and your skin seems to soften. A weird sucking sensation envelopes your crotch, and you see your penis shrink rapidly to nothing but a tiny nub around which all its nerve endings coalesce, while your balls move up inside you and your scrotum sinks into your crotch until a passage forms in its centre and it becomes your vaginal lips.
Noticing your girlfriend blushing hard in the mirror, you turn to her and wink. "You alright, babe?" you ask, guessing what's happened.
"Yeah," she mumbles, trying not to stare at your tits. "I, uh-" she chokes back a laugh. "-I think you turned me into a lesbian."
"Oh really?" you purr, trying to hide your own arousal as your pussy moistens at the realization she's horny for you. "What do you wanna do about that, then? Wanna try something with me like this? Want me to turn you into a guy so you can pound this pussy? Want me to turn back into a guy so I can pound yours? Want to turn us both into guys so we can go from lesbian to gay?"
She swallows hard, and then answers...
