A Sorority House (male, straight)

You know it's immature but you are invisible and can walk though walls. You might as well do what your college age self would have done with these abilities, it's not like you are likely to ever have the chance again.

You concentrate on Beta Alpha Epsilon, the sorority at your old alma mater most famous for the sexiest girls on campus, and suddenly you are standing outside it. You walk up to the door and walk though it, finding yourself in an entrance area. You can see a number of college age girls walking around and, thankfully, 'BAE babes' are still the hottest on campus.

Since you seem to be following the dictates of what 'teenage John' would have done with invisibility powers you look around the halls until you find the bathroom where some of the girls are going to shower. Disappointingly the showers seem to be individual stalls rather than the wall of shower-heads that porn and 1980s movies led you to expect. However, you can see the warm pink glow of low level pleasure from most of the stalls (presumably because their inhabitants enjoy a warm shower after a long day of classes) one is glowing pink to a level that is almost blinding.
You put your face through the door of this stall and see it is inhabited by two lovely ladies who are enjoying each other's naked bodies in a way that makes those 'lesbian sorority' porn movies look positively soft core.

The aura of joy and sexual pleasure they are giving off is strong enough to invade you own and you find yourself caught up in it. It's an alien yet wonderful feeling as you experience what it is like to be made love to by a woman *as* a woman. To feel her fingers inside you, her hands on your breasts, the understanding of your body that only comes with also being a woman.

You pull back before you can get totally lost in the feeling. Still you are more aroused, and amorous, than you can ever remember being. You want ... no need... to find someone to make love to ... you don't just need sex you need to share all the pleasure and joy that is vibrating through you. You won't be satisfied until you give someone the best sex of her life.
