=== Additional Info ===
I’m going to be totally honest, I thought today’s release was My Sister Sleepover until about ten minutes ago.
By the time I remembered that Christmas Wishes 3 was scheduled for today, there wasn’t enough time to finish it. So, we’re just rolling with it and those two release dates have been swapped.

== Plot ==
Three high school girls, Jill, Raven, and Sierra are having a sleep over glad to get together one last time before they all graduate and head to college. They start the night talking about prom but Sierra is nervous about it as she's still a virgin and is unsure about going all the way with her date. Unknown to any of them however Jill's little brother Ron is hiding in closet spying on the girls. As Sierra begins to tell an embarrassing story Ron pulls out his phone and tries to record it through the closet screen. However at the very moment he tries to hit record his best friend Cory tries to call him. While he stops the phone after one ring the girls hear it and find him much to his embarrassment and their anger. When they spot the phone is his hand Jill threatens to tell their mother but Ron begs them saying he didn't record anything and promises to leave. While the girls are still angry Raven pulls the others two aside and suggests something fitting to punish him. The others agree to the plan and tell Ron he can hang out with them but he has to wear slumber party attire. The girls then force Ron to put on a girly outfit threatening to tell his mother if he refuses. As Sierra is getting him dressed however Raven displays a Mana Mark revealing that she's a Silver Blood Sorcerer and once Ron puts on the panties and skirt she begins to transform his body into a girl. The girls begin to laugh enjoying his reaction when he sees himself shrink and grow breasts. Ron begins to panic and begs them to make it stop saying he's learned his lesson but the girls refuse to let him go until they're satisfied. Ron tries to leave to tell their mother thinking this is taking things too far but Raven bind him with another spell and forces him into a chair so Sierra can do his make up and finish his transformation. The girls promise to change him back once they're confident he's learned his lesson but Ron is still freaked out and begins to panic once his face, voice, and crotch change completing his transformation into Roxanne. With the transformation complete the girls fawn over him (now her) and laugh at his comeuppance. Roxanne looks at her reflection in the mirror and admires her new figure but still insists that this has gone too far and she's learned her lesson. As she tries to argue with the others to change her back her phone rings and its Cory again. When the girls see who it is they get the idea to make Roxanne's final punishment to talk to him and ask him out to Prom. They then hand her the phone and tell her if she wants to change back then she's going to have to go on a date with her best friend. They pass her the phone and she answers hesitantly as the girls watch in amusement.
