As Jeff was looking thru the jock straps, Mike had snuck over to the girls locker room, he some times plays pranks on the girls. Girls locker room was empty. Peaking out from the top of one locker was a box. He climbed on a bench and pulled the box off the top of the locker. The model on the box could have been the older sister of his last girlfriend, it looked like a pink bikini and a see thru pink dress, called I think a cover, thru why would you cover a bikini, Mike does not know. What Mike does not know would fill a lot of books, in fact if he was a girl, that girl would be a bimbo. The urge to try it on hits him. He opens the box and grins as he pulls out what he thinks is the bottom of a bikini. He takes off his jock strap and steeps into the bottoms, pulling them up his legs that become sexy, curvy, girls legs with dainty feet. As the thin square touches his balls, dick and hips, His hips grow sexy girl wide, his dick shrinks to a cunt, the lips of his dick grow absorbing the rest of his dick., his balls invert to become her pussy, womb, and ovaries. If he had looked a the box more closely, he would see it says lingerie. He pulls what looks like a bikini top out. She puts the top on, her arms shrink and curve, as fingers grow thin, longer pretty. As the cups touch her chest, breasts grow from her chest until they reach 34c cup. She grabs what she now knows is a negligee out of the box and slips it on. As the negligee flouts down her body, her hair grow down her back, her face becomes a pretty girls face. Her waist pulls in completing the change. Michel`s giggle echoes throw the locker room. Jeff follows the giggles to his girlfriend Michel. Jeff and Michel kiss and remove their clothes. Jeff is kissing Michel`s hard nipples and she lays on the bench with her legs open to her wet pussy. Jeff slides his dick inside her slowly teasing her. Her pleasure builds as his dick fills her pussy. As they wiggle faster and faster she has orgasm after orgasm until the line between orgasm blurs into peaks and valleys of pleasure. Her moans and giggles drives Jeff over into his own orgasm, spraying his seed up into her unprotected womb. They clean up, get their street clothes on and leave the locker room hand in hand.
