My Girlfriend Let Me Creampie Her In The School Bathroom Today

So my girlfriend has been on birth control for a while now and we were just eating lunch together as per usual today. However, before the next class started, I told her I had to go to the bathroom. I went to the bathroom but I didn't know that she actually followed me in soon after! I was kind of freaking out since I knew a teacher would flip if they saw us together in the bathroom.

My girlfriend told me she knew how stressed I was the past few days with several big quizzes coming up soon. She wasn't wrong and I had not cum for several days. She took me into a stall with her and began undressing me. I did the same to her and she could tell that I had a massive erection in my pants and complimented me as usual upon seeing it pop out. My girlfriend told me my cock was as big as ever, she thought I might've even grown a bit since the last time we had sex. We started to fuck standing up just like that. She told me it was okay to fuck her without a condom because she was on the pill. I started to speed up since I was worried someone might come in and hear us.

I was very close to ejaculating and I asked her where I should cum. She told me to drain my balls inside her and that's pretty much all it took to send me over the edge. I shoved my cock in her balls deep and drained every bit of cum I had straight into her pussy, completely filling her. As I pulled out I got to see some of my creampie drip out of her. As if it couldn't get any hotter, my girlfriend pulled up her panties with my cum still inside her pussy. She said she could feel my baby making sperm swimming around inside her. We both exited the bathroom to go to our next classes. I spent the rest of the day imagining her walking around with her pussy filled with my sperm and also wondering what the actual fuck just happened?
