She found that girls were more excepting than boys, but have meet some hermaphrodites. She had been drinking in a co-ed gay bar were she meet Dug, she had been left by a girlfriend who had just used her to get pregnant with twins. She listened to him complain about his ex-boyfriend and his device he is building. A trained engineer, Alex boldly asked if she can join him in building the device. Max is Alex`s date to the party. Max is a pharmacist at the hormone store and was raised a girl but grows a dick and balls as a teen, her parents were founders of the hormone store so they just excepted their strange daughter. Alex and Max meet a month before the party and both use the she pronoun fore them selves. She in fact had built a back up device witch is in her purse. Beside her and Max, the only ones in dresses are the four women part of a polly six person group. Bob is bisexual so the wait staff are good looking college students in thin swimwear. Alex`s device is the gun on the belt of her cowgirl dress. She sees Dug power up his device, so Alex presses the power stud on her gun. Ales steeps into a small room with twelve people (eight guests four servers) and fires her gun in a wide beam. The eight guests men grow breasts and wider hips with female insides. The four servers women grow dicks and balls. The four guests behind the servers lift their skirts and slides their dicks into the servers pussies. The four guests in front of the guests now wearing dresses lifts their dresses and turn around so the servers can stuff their dicks into the guests new pussies. The dicks pump in and all most out of the pussies then back in making the pussies come a few times before the dicks exploded into their pussies. Alex walks away to watch what Dug`s device is doing. Flowing moans and giggles, Alex finds the polly group with the boys screwing two of the girls from behind as they eat out the other two girls. Alex fires her gun and the boys grow breasts, hips, wombs and ovaries. The four girls grow dicks and balls. The girls in the middle stick their new dicks into the pussies of the girls laying the front of them. Soon the hole group is having orgasm after orgasm as the dicks shout into the unprotected pussies. The six of them split up into cuddling couples. The two dick girls that had not come from their dicks began playing with each other. The two of them stuffed their hard dicks into each others pussies. The two of them wiggle together until they come from their pussies and dicks.
