He is a boy but the world seems all reversed somehow

As the world shook and reformed around him he found himself now waking up on a familiar bed in his room except Kelly was there "Jack are you ok you passed out on my bed I know you mentioned not feeling great earlier but I was just playing my video games and I heard you walk in muttering then you passed out on my bed for like an hour, it was like you fainted or something I've been trying to wake you all this time are you sure your ok"

Jack slowly tried to get up but he felt dizzy and weak and somehow strange like something was off. he could remember all about the reality changing and his original reality and everything and this was definitely his old room with blue wallpaper bedsheets and his gaming PC everything seemed distinctly male? but he was thrown of by Kelly having said it was her room.

Jack noticed that the room kinda smelled a bit musty like sex kinda like how it used smell when he masterbated loads in the past. The smell made his nose tingle and his belly and crotch feel strange. Looking up at Kelly he could help but feel she looked a bit taller than before and maybe a bit more toned or muscled.

"Ugh Kelly I feel like weird, I'm kinda dizzy after you changed something and isn't this my room? isn't it? Anyways why did you think it was your room?"
