Trent managed to get herself back home without much issue. She had opened the front door and looked around to see if there was anyone there to see her in her new form. "Trent is that you?" his mother called from the living room.
Trent thought super fast and tried deepening her voice and said "Yeah... Feel not so good... going to take a bath, maybe that'll help..." then started running for the bathroom. His mother went to take a look and right before Trent slammed the door she saw a little bit of a dress. She wasn't quite sure if she was just seeing things though.
She muttered "Alright i guess..." Trent meanwhile was in the bathroom with her dress on and her normal clothes in a bag. she turned on the bathroom fan and started to fill the bath and then turned to her dress and found her cleavage. She blushed a bit convincing herself that's it's her body, and he needs to take the dress off. She took off the dress and noticed that her normal briefs had turned into a bra and panties. She muttered "Well ain't that convenient magic?" The panties were easy to take off, and Trent managed to take off her bra. Her breasts jiggled a little. Feeling a little embarrassed Trent saw her reflection in the mirror barely then curious took a better look. Her face looked cute to her, a lack of blemishes, and her hair had even grown a little bit. She unconsciously crossed her arms and noted some squishy masses on top of them then quickly put her arms down surprised. Looking at the bath it was basically filled so she went and turned off the water and went submerged herself... noticing her breasts were kind of floating in the wild. Looking at her body she thought "Ok... this'll be your body for the week... may as well get comfortable... How about we figure out how this body feels and know what it's like." She then started to take her hands and explore her body moving her hands over her smooth curvy flesh. Squeezing her butt a little figuring out the firmness, masturbating a little, and then finished with her breasts. Starting at the base where they connected to her chest, and then groping their underside, then the top side. Tweaking the nipples a little and noticing how they hardened and stiffened. Going for the loofah she scrubbed her body. This felt great. Looking back to her cleavage she felt aroused and went for her crotch. She grabbed her dick and started jacking it, and even managed to bend and put the two pillows of flesh around her dick and just go at it and cummed... Then she realized "wait... that was my dick." Trent looked at her cleavage which was slowly being sucked into her chest as her body grew larger and hairier. Trent was now a guy again, and quickly washed off the cum and got out of the bath and dry. His underwear were briefs again, and he put on his old clothes. He folded the dress then thought about how to explain the dare to his mom and maybe sister... if he even had to. He got out of the bathroom as the water drained and managed to sneak to his room and put the dress away into his dresser.
