Underwear Transformation - Tumblr Posts
So last week was my birthday, and a few of the guys at my party decided to merge with my underwear as a birthday gift. Theres still room for more people if more people want to jump in or lowkey if you want to put people against their will in there thats fine too. All you gotta do is make contact with my undies. Only catch is EVERYONE has to agree to stop being merged to set everyone free. Its been a week and my 20 or so friends are still in here so it can be a while. But these are my favorite pair of undies, so I won't be taking you guys off until you guys unmerge yourselves.
It was first time when you saw yourself in a mirror after you was transformed into your lean roommate's favorite swimsuit. First you though that it will be funny to rub and scratch his junk in public pool while he wasn't aware of your presence. But something goes wrong when he left you on after pool. He didn't pull off your damp body and wear you all day along under these pants. Turns out that you was rather comfortable than original swimsuit so Seb was able to use you as daily underwear every day. You are waiting for a rest in laundry basket to transform back, but Sebastian keep using you during his routine at least 8 days. You are still clean and nice because he visits pool every day. Seems like you set a trap for yourself...
Trapped in the Briefs
“You’re in for it now, Mark. You always complained about my smell, and now you’re going to get a front-row seat,” grinned Ethan, holding the transformation gun. Before Mark could react, Ethan zapped him, and Mark felt his body contort and shrink until he was nothing but Ethan’s tight, musky Gymshark briefs.
Ethan pulled the briefs on, trapping Mark in the suffocating fabric. The smell was overpowering—sweat, musk, and an unbearable staleness filled Mark’s senses. To make matters worse, Mark’s senses were heightened after the transformation. Every smell, touch, and sensation was intensified. “Oh, by the way, I made sure your senses are super sensitive now. Enjoy!” Ethan chuckled.
Ethan, who was dairy intolerant, made sure to consume a large amount of dairy and protein right after putting on Mark. The effect was immediate and brutal. As the day went on, every movement was torture for Mark. The heat, the pressure, and the constant friction were relentless. But the worst was yet to come. Ethan smirked, adjusting his waistband. “Better hold your breath, if you can.”
Without warning, Ethan let out a loud fart, the rancid smell seeping through the fabric and into Mark’s very being. The odor was nauseating, and there was no escape. Ethan made sure to keep consuming dairy products throughout the day, ensuring a steady stream of gas.
Ethan didn’t stop there. It was the middle of summer, and he decided to go for an intense workout session at the gym. The sweat poured off him, soaking into the briefs. Mark was overwhelmed by the combined assault of sweat, musk, and the relentless farting.
Ethan didn’t bother showering after his workout. He wore Mark all day, and by the end, the briefs were soaked with sweat and reeked horribly. The constant sweating and gas attacks were unbearable for Mark.
As night fell, Ethan stripped off the briefs and tossed them carelessly into the laundry hamper. “By the way, you’re going to stay that way for the whole summer,” he laughed. “See you tomorrow, Mark.”
Mark was left to endure the suffocating darkness, dreading the torment that awaited him for the rest of the summer.
