Yes, if you'll come to our small party

Isabel happily took Mike up on his offer. "Well, Yui and I are having a small party tonight. You're welcome to come if you can give me a ride home" she smiled.

Mike seemed to think about it for a moment while he stared at Isabel, who now had a hand on the waistband of her sweatpants. They seemed to be getting heavier by the second and she didn't want them sliding down her legs. "You got it!" Mike said happily. He slapped the seat behind him and said, "Hop on. And hold on tight to me."

Isabel happily complied and straddled the bike behind him. She wrapped bother her arms around Mike's torso and smiled as she squeezed him tight. Her sweatpants dipped even lower on her ass, as the top of her thong came into view. The cold rain didn't seem to bother her as much anymore. As Mike revved the bike and took off, Isabel's butt slid back on the seat a few inches, so she tried to grip Mike even tighter. This only helped to drive Isabel's pants further down her backside, and a few more minutes of torrential downpour later, her shapely ass was hanging completely out of the pants.

Isabel felt the water hitting her bare skin, but decided not to try and fix the pants until the ride was done. She didn't want to risk falling off and getting injured, especially since they were only a few minutes from her house.

Mike weaved in and out of some stopped traffic to try to get Isabel home quickly. A few honks followed in his wake, some of which were also for Isabel basically mooning the stationary drivers.

A few minutes later, Mike pulled up in front of Isabel's place and she carefully got off her bike. She took an extra second to pull her sweatpants up over her ass again before thanking Mike again for the ride.

Mike, who had just gotten a nice view of Isabel's thong and ass, shouted "I'll definitely see you later tonight!" before driving off.

Isabel rushed through her front door and close it behind her, glad to finally be out of the pouring rain. She was dripping wet, and her outer clothes were still completely see through. Her entire form stood out sharply against her soggy garments.

"Nice bra." Yui said with a smirk from the kitchen as Isabel began walking towards the bathroom.

"Very funny." Isabel said, covering her chest with her arms. "Mike's gonna swing by later tonight." she said with a smile.

"Ooh, good call." said Yui, picturing the guy herself, "How'd you swing that invite?" She paused, looking at Isabel struggle to keep her pants up for a moment before adding, "Nevermind."

Isabel turned and made her way to the bathroom, wanting nothing more than a hot shower and to finally get dried off. She hung her soaked shirt and pants up in the bathroom and enjoyed 15 minutes of steamy bliss, grateful she hadn't embarrassed herself in front of Mike. Finally she turned the water off and grabbed a towel.

She wrapped it around herself and made her way towards her bedroom. Suddenly, she heard the doorbell ring and heard Yui call "Coming!" Shoot! People are arriving already! I must've taken longer than I thought. Isabel entered her room and closed and locked the door behind her. She sighed, feeling secure in her room, and took her towel off and began drying her hair.

Then Isabel realized...
