Alright, this is the first caption I've started and finished writing since starting that job I spoke about a while back. I hope I'll be able to keep at least this pace up even with full time work, but it remains to be seen.
Caption number 77.
"Ahh~ one of them is really looking through it, what a creep hahaha~!" Realising what was on the other side of the mysterious hole he had curiously tried to look through, Yuudai Tomioka quickly backed away from the wall while blushing brightly. "No way Chii-chan, really?" "Yeah, let's invite him over to "our" side~" "S-sorry! I really didn't know, I didn't mean to-" A sudden blast of magic shooting through the peephole cut him off, as he was thrown backwards and fell into the onsen's water. His body rapidly began to heat up from within.
As he struggled to regain his bearings, his body rapidly started to slim down. His hips widened as his thighs thickened, putting pressure on his dick, until soon, it shot up into his body and vanished. Replacing it, a sensitive set of folds opened up in its place, causing Tomioka to forcefully gasp and take in water. While coughing up water, he finally managed to get up just as a shapely set of breasts inflated into existence upon his chest.
His body was starting to feel stranger and stranger, but with his wet and now much longer hair clinging to his face he couldn't quite see what was going on yet, but that would soon change. "Uuhg... I-I said I was sorry... -?! Was that..? M-my voice?" She stammered in surprise as she heard her new voice for the first time. Hastily, she started to wipe her hair out of her face so that she could see her body, causing her hair to magically style itself in a way that mostly kept it out of her face.
"I-impossible?!.. I turned into... -!" She then heard her friends who finally finished undressing come outside. Tomioka hastily dove behind a rock to hide her new form from them, but one of them saw something. "Oi Yuuka! Whatcha standing behind the rock for? It's just us!" It was Haruto, but her friends were the last people Tomioka wanted to be seen by. There was not much she could do though, as he was already wading through the water towards her.
"What's the matter, Yuuto? Normally you'd tell me not to call you-" He abruptly froze up, causing his glasses to almost fall off. "W-what's a girl doing in- S-shhh..! I-it's me, Tomioka Yuudai..! I know it sounds unbelievable, but I got turned into a girl somehow, and I-I don't want the guys to see me..!" After an awkward silence between the two, Tomioka suddenly realised that her full breasts were completely on display, and that Haruto was staring. She quickly used her arms to cover them while anxiously awaiting his response.
"Alright, I believe you. I'll even help you get out without the others noticing." "Ah, that's a huge relief, thank you so mu- Hooold up~ In exchange then..." Haruto grinned lecherously, before continuing. "Let's lose our virginity together~ You're curious too, right, Yuuka-chan~?" He put strong emphasis on the nickname Yuuka, which Tomioka had always disliked due to it sounding like a girl's name. She laughed nervously. "Y-you're joking, right Haru-san?"
Haruto didn't laugh though. Instead, he stepped away from the rock Tomioka was hiding behind, and called for the rest of the friend group's attention. It was clear to Tomioka that he was being serious, so in a hushed voice, she quickly said what he undoubtedly wanted to hear. "O-okay, I'll do it..." Haruto grinned in response, before directing the other's attention away from Tomioka. Tomioka quickly took her chance, blushing brightly as she scurried back into the changing room. She couldn't help but imagine what doing it would be like as a girl, and soon she'd get to experience it...
