"Oh my god, aren't you Mrs. Bradley’s young son, Eric?" your parents said as they're surprising your girlfriend just turned into your neighbor, Mrs. Bradley’s youngest son, Eric Bradley. But anyway, thank god that they didn't found out about this.
"Hey, there." your transformed girlfriend in the form of 10-year-old Eric, her voice sound a little deep and boyish, plus her attitude also mentally like a 10-year-old boy. "I was just playing with big bro here then he's off."
"Aww, honey. You didn't tell us that you're babysitting Eric." your mom responds as she's gently pat your head. "Anyway, we'll go change our clothes and then me and your dad go to shopping and prepare to you both dinner, okay."
"Okay." you and your shapeshifting girlfriend/Eric nod at them as your parents head to their room change their clothes. While they change, you close your door from your room and then look back to your girlfriend who is now a little boy and said:"Oh my god, that was a close one, babe."
"I know, and I didn't know what to do. I was panic and thinking about someone else I could turn into. When I hear a footstep coming to your room, I just quickly turn into my BFF'S younger brother, Eric." s/he explains. "But I'm so sorry for making noises and just change into a boy without your permission."
"It's okay, babe. I don't mind that you're change into a boy." you reply.
"Wait, you do?" s/he asks.
"Of course, I don't mind. And beside, I was thinking about bi-curious if we could do that when we were interrupt by my parents." you tell her/him as s/he smiles at you. "And while my parents leaves the house do you wanna have a gay sex?"
You ask as your shapeshifting girlfriend nod at you. After a few minutes later, your parents drive off and then head to the grocery store to buy something that could prepare for dinner. You then carry your former girlfriend who is now a 10 year old boy and kiss her/him on the lips. "Oh boy, that's strange kiss." s/he impresses. "But it's fun."
"The fun is just about to get started, little Eric. Let's take off our clothes, shall we?" you asks as s/ he's nodding. With that, you both takes off your clothes until you both naked. Once you both naked, you look down to your shapeshifting girlfriend/little Eric's body as he has a nice feminine figure and a small erected little penis. Then your girlfriend/Eric told you sit down on the sofa while he gives you a blowjob. When you're finally sitting on the sofa, your girlfriend/Eric start to lick and suck your big hard cock fill in her/his mouth. Then s/he takes a deep throats as she could and thrust faster. Finally, you couldn't hold any longer, but just cums release all of your seeds in her/his mouth as he drinks all of it. "Mmmm, your penis fills a lot of milk in my mouth right now. Why don't we put this into my butt?" your shapeshifting girlfriend/Eric asks as s/he get in your lap and then put your cock into his butt as you both gasp at the feeling, as you are now completely inside her/him. After settling a little, s/he begins to move up and down rhythmically. Soon after this s/he speeds up more. With the newfound speed, your former girlfriend finally hits the spot and forces you deep inside of her where you finally explode. You hold her/him tightly against you and kiss gently as you continue to release your seed. Both of you exhausted, you fall on the again. She or rather he smiles and breaks the silence. "It's strange, isn't it? Having sex with a 10-year-old boy it's kinda strange."
"Well, I don't think it's strange having sex with a 10-year-old boy who is my shapeshifting girlfriend turn into." you reply and you continue to kiss him/her once more.
"So anyway, would you like me to stay like this or just turn into someone else?" your shapeshifting girlfriend in the body of young Eric Bradley asked as you're try to think.
