Dan silently fidgeted with his seatbelt while Kim focused on the road, which was increasingly flustering him. Not only was it annoying--how the belt rubbed against his breasts--but it made him feel funny between his legs. As the car ride continued, the struggle got worse. Dan's face felt flush with frustration, and he was grinding his knees together absentmindedly to try to keep it together. They were getting close to home, and he really felt like he needed to pee. Again. But he didn't want to give Kim the satisfaction that she quite obviously was enjoying the irony of Dan's female bladder. Then again, he felt he somewhat deserved it after how many times he made fun of Kim for the very same reason.
There came a point where he felt like he couldn't make it. So he put his pride aside and spoke up. "Uh hon, I really need to piss again, like...really bad." they passed a few fast-food places around the corner from their home. "Can't it wait? I swear, every five minutes with you women!" Kim flashed him a shit-eating grin. Dan gritted his teeth and pinned his knees together.
They rounded the last corner and pulled into their driveway. Before Kim could even turn off the car, Dan lept from the passenger side, and dashed to the front door, keys in hand. As Kim watched Dan tear toward the door, she leisurely got out and made her way up, locking the door. She heard the crash of the keys hitting the pavement, and a very pained, "Noooooooooooo" echo from in front of the door. Kim walked up to survey the damage.
Dan was slouched to his knees, legs pointing opposite directions. A steady stream of shame was dripping out from under Dan's skirt, as he hadn't been successful in holding it in. His shirt was also a little wet, specifically around the nipples. He was sniffling--determined not to give into tears. His face was bright red with a mixture of embarrassment and the programmed libido changes kicking in.
Kim comforted her victim and helped Dan to his feet. She unlocked the door for Dan, "Don't worry, nobody's around in the neighborhood at this time of day. Go inside and get yourself cleaned up. I'll join you as soon as I clean off the porch. Kim closed the door and retrieved the hose, performing the usually mundane task of cleaning the patio, putting a little extra gusto into getting some extra leaves from the corner.
As she was done, she coiled the hose and walked inside. She closed the door, and walked toward the bathroom where she expected Dan's changes had more or less "climaxed."
Sure enough, Dan was in the shower, massaging his obviously increased bust with one hand, and his empty cunt with another. As he heard the door open, Dan turned to Kim and pleaded, "Oh my god, as much as I play with my dirty pussy, it just aches like it needs something. Help me out Kim." Kim smiled, and unzipped her pants. Dan eyed the bulge in Kim's underwear hungrily.
Kim finished disrobing and got into the shower, and Dan practically impaled himself on what used to be his own dick.
