Perhaps

You race into your room to hurriedly get dressed. You drop the worn panty in your drawer and pull out another. At this moment any one of them will do. The towel hits the floor as you quickly pull up, you guessed it, a thong style panty. The material is solid and stretchy micro fiber and all edges are trimmed in a contrasting colored white on black thin lace. After all, you were a woman when you ordered the panties and these are clearly a woman's pair! Since you are still a woman in your crotch area only at this moment, the fit seems to be ok in that the front fabric covers your slit all the way back to the taint where it becomes butt floss then exiting your crack with another smaller triangle of fabric. Maybe it's your male butt size difference to female, but it seems like the floss part is longer than it needs to be. At this time, however, you have no time to ponder it and pull up on the thin well, nearly non-existent sides until the entire garment is home. After that, on with your jeans and a polo shirt. You're sitting on the edge of your bed, putting on socks when David exits the bathroom turning on and leaving on the fan.

"Ok, Patrick, What's going on man? I get home and you're taking a bath!" Guys don't usually take baths. Are you ok? Then, while rushing out of the bathroom, I don't blame you, a pair of ladies underwear falls out of your pants. I understand you've been getting a little and maybe she left you something to remember her by but Dude, you're making me wonder about you being a little kinky and stuff, Man?"

You bend down to pull on your shoes, exposing a whale tail as the bottom of you shirt slides up your back. David rushes a step and a half over and grabs it. "The gigs up, Pat. time to come clean. How do you fit your junk into this thong thing and why would you try? You're not gay or something?

"Last week", you let out a heavy sigh, " The guys at work were talking about X-Change. It seemed like, by the way the discussion went that it was safe and effective and you could experience what it would be like being the other gender and then change back to your normal self and all would be the same. Well, I thought, as a man, I sure wasn't getting any action and so I thought maybe I should give it a try." David jumps in, "Holy crap!" "Just hang on a minute. There's more to this and its not my fault!" You stop him.

After I took a basic pill with that the change lasts for about four hours, I became this really hot babe, Patty. While I was Patty, I took her measurements and ordered her some clothes on-line. That's how I got the panties. "Ya but," David started. "Hold on", You shush him as you stand un-snapping your jeans, "Then when I changed back from Patty to Patrick, everything changed except this." Sliding your pants lower and exposing your thong covered groin. "Dude! That's fucked up!" David exclaims wide eyed as he's locked in on your camel toe. "Pat, I'm sorry this happened but Man I can't believe you would try X-Change." as he walked to the kitchen and pulled a couple of beers from the fridge. "So you are a real live cuntboy now!?" You explain, "Well after I spoke to the folks at X-Change, They are trying to come up with a fix for this but it might take up to six months. Mean while you and Tammy are the only ones that know and I can't have this get out to the world, OK?"
