After a while when both of you finished your private sex, you and the 10-year-old boy who was your girlfriend inside the suit enjoy the routine of hanging out with each other in the house, you and the young boy playing games, watching TV, playing sports, hide and sex game, kissing, and even make-out like boys. You and the little boy in naked bodies are so enthralled with cuddle sessions while enjoying watching some adult animated series like Smiling Friends on streaming services. You know, you kinda like your girlfriend wants to stay that way, plus she loves being a little boy so much. Not that you disagree with her or anything, it's just that you're starting to feel like you're babysitting your sibling you never had, but somehow you're enjoying it. It's kinky that you want your girlfriend to be a little boy that you want to "play" with. When the episode finally finished, you decide to turn off the TV as you both get off the sofa and stretch out of the body. Then, your girlfriend-in-the-boy breaks the silence. "That was a fun episode. I can't wait to see what's next."
"Yeah,... it's too bad we have to wait until next week," you reply. "Anyway, now that it's done, let's say we should continue our time, shall we?"
"Sure thing, big bro. I love to have fun with you," s/he responds as you're shocked.
"Wait, what did you just call me?" You ask.
"Oh sorry about that, honey. I must have slipped my thought for a moment." That's strange, she's never had that before when she became a little boy. "Well, never mind about that. What shall we do next, big bro? Can we go to the arcade to play a game, how about a theme park, or will you take me to the store to buy a cool action figure? Or go to the movie theater, or even how about going out to play ball with me?"
There is it again, you start to think that your girlfriend's acting like a kid after calling you big bro like you have a brother. This must have been the bodysuit doing that it alter her mind. Or maybe she just pranked you or wanted to roleplay with you. This is starting to mess with your head, but never mind you thought that she just messing with you. "Well, I was thinking about sex like we used to do, babe," you answer as the boy is confused about what you say.
"Sex? What is sex, big bro? And why did you call me 'babe'?"
"Okay, babe, real funny. Stop messing around." You say to him/her.
"Oh... s-sorry, hun. I just can't help myself for calling you that. Wait, did I just call you hun?" Your girlfriend snaps back as she or he doesn't know what he just said. This also concerns you when your girlfriend starts to mentally become a boy by the suit. You look over to the young 10-year-old boy in front of you who was your girlfriend you change by the suit. You think for a moment as you ask yourself what should you do now. Should you change your girlfriend back to normal or you want her to stay this for a while and then change back?
