Virgin creampie accident

First accident (18M) with exgf (18F)

When me and my exgf (we’ll call her breanna) first started dating, we were both virgins and dealing with the hormones of being teenage virgins. Our first time having sex was actually in public. We went for a “walk” and stepped off a hiking trail to have sex against a tree. Not really memorable, but we both learned we hated condoms, so we being the dumb kids we were, stopped using them and felt pulling out was good enough.
We would spend our weekends together since we lived in different towns. When we were together, it was almost like the entire relationship was based on seeing how we could discretely fool around. Typical horny teenagers, hand jobs in the back of the car while the parents drove, fingering under the covers while everyone was watching TV, but eventually it wasnt enough. When her mom and sister left to go to the store, and her dad was out mowing the lawn, we decided to sneak into her room to fuck. The shocking pleasure of first sliding into her unprotected pussy, and the flaming electric ecstasy of her grip on my essentially virgin cock (first time without a condom) sent me into a spiral. I plunged deep and pulled her onto me as deeply as I could and felt myself getting close immediately. She moaned and hugged me, and we started fucking hard and fast right away. It was moments inside her when her dad came in the house and slammed the door. We were both dressed and on the couch in seconds!
