You fumble around for the zipper on your back. Then where there was no zipper before, you feel it materialize ib your hands. You're relieced, but still stressed. You pull it down, creating an opening. You grab the opening and pull the skin off. Your vision turn black for a moment, but then you emerge out of the teen boy skin as an adult man. The skin you used to wear is scrumpled at your feet, and you step out of it, one foot at a time.
You feel calmer because it's resolved, you got out of the skin, but also, you feel like there was an intensity to your feelings when you were thirteen which immediately dispersed once you returned back to a more collected adult.
You look at your girlfriend. She's still in her skin. Now you get to look down at her again instead of being slightly shorter than her. She's a bit of a mess, sweaty, clothes not properly on, and a bit of remnants of your cum on her. Though, you still find her hot, even with your restored age back. What you did in the movie theater is still fresh in your mind.
"Aren't you going to get out of the skin?" you ask her.
"Um, not yet, I think." She smiles. Then, she looks over herself. "I like it, being like this, young and stuff. Though, I do like need a shower." she giggled.
"How long are you planning to stay like this?" you ask a little worried.
"Well," she starts. "I was hoping, that maybe, um." She looks at you up and down, then she looks down at her feet. Was she acting shy? "Maybe that we could, um..."
"Fuck? You want to have sex?" you blurt out.
"Yes." She blushes slightly. "I want me and you, the real you to do it. Just first, I really need a shower. Like, I feel super gross. You just wait for me, okay?" she rushes to the bathroom.
You wonder if you should have said that, for you to fuck. When your adulthood returned, as did that iffy feeling about her being younger. Still though, you did want it.
You wait for her shower to be done, during which you look at the skin you wore. You remember the mall date, and just thinking of your teen girlfriend makes you hard. You rummage through the pockets of your skin's pants, and there it is, the photos you took in tge booth. You flip through them. You linger at the third one, where she's flashing the camera. Your teenage self looks absolutely flabbergasted in the photo. You laugh. It almost feels nostalgic, even if it happened today, there's like a distance to it, once the skin is gone.
After a while, your girlfriend comes back from her shower. She's wearing a towel around her torso. Her hair is still wet, sticking to her neck.
"Hey," she coos flirtily at you.
"Had a nice shower?" you ask her.
"I did. Oh, I did. Especially since I was thinking of what would come after." she bit her lip.
You approach her, and as soon as you do, she throws herself at you, her towel falling down, revealing her naked teen body. She giggles. "Fuck me."
You go for a kiss, but she's so short, so you scoot her up, fondling her pert ass during which, and lift her up. You start st her neck, kissing it, smelling her, her fresh clean aroma. You kiss her lips. She responds hungrily, but you're still very much taking the lead.
The iffiness around the apparant age gap, you wished you could have pushed it away, but it was still there, and was it maybe turning you on as much as it weirded you on. You don't know if something in you has awakenes, but you find it so hot how young she is, how you get to fondle her body on the cusp of womanhood.
You push her on the bed. She's laying there, and your dick is facing her.
"It's so big," she comments.
It does look very big compared to her. It feels nice, but also makes you a bit worried for her. "I don't have to put it in. I can use my fingers, or tongue," you suggest.
"No. I want it in me. I want ut in me right now. I am ready."
You're happy to hear that, so you enter her. She's tight and very tense, so you move slowly.
Her body twists, but despite your concerns, she yells: "Deeper! Put your adult dick in me!"
You push it inside, and her body jerks. She's so tight, it's almost painful until her body starts relaxing a bit.
"It's so good," your girlfriend exclaims.She laughes, seeming like she's high on andrenaline.
You start properly thrusting inside of her. Every rhytm causes her small body to move, but she's still smiling, even if she's now yelping and screaming as she's getting fucked. "Harder!" she yells.
You fuck your teen girlfriend roughly, just as far as you're willing to push her body. Her body convulves, and she screams. "Yes!" You feel her thightening around your dick.
She's so sexy, and this so hot. You're about to cum, and then you do. You shoot a burst of cum in her. You shoot you entire fill.
Then, you let her go. She's laying on the bed. You're standing in front of her. She's laughing and her gaze is hazy. She looks at you and seems almost dizzy.
You smile at your teen girlfriend
