When your boyfriend walks out of the bathroom, you see the person who walked out of the bathroom wasn’t your current boyfriend or former girlfriend anymore, but rather a naked 10-year-old boy that you turned him/her into.
Your boyfriend/former girlfriend or the little boy speaks with his young, joyful, and boyish baritone voice. "Ahh, I'm so much clean. Teehee..." His mind had also shifted to suitable of the appearance. "I can't believe the resort could be so much fun."
You then begin to say: "I glad you like the show, kid."
"Hey, don't you dare call me a kid. I might 10, but I'm a big boy. Plus, you're my babysitter." You then realize that this kid has his mind changed to know that you're his babysitter and s/he is a little brat you taking care of.
You then ask the "boy" if s/he knows what happened earlier, and he says. "Well, yesterday was my birthday, but my parents were busy and didn't have to spend with me. And then, you were taking me to the resort for my birthday, which got me excited and happy. Plus, you and I were enjoying each other, playing the arcade, swimming in the pool, and also... having our privacy."
The little boy then takes off his towel on his hip and then reveals his little erected penis. Of course, you also did alter his mind a little bit, but still keep the memories of your former girlfriend you loved in there. Plus, it's kinda wrong to have a relationship with a little boy, but you think it's kinda kinky. "Oh, I didn't know you were still horny. Are you ready for another round?" You smile.
"Absolutely," he nods as he walks closer to you while you sit on the bed. He then climbs up your laps as s/he kisses you on the lips.
