This was during highschool and I would flirt with any girl I liked, I eventually started dating my ex gf in the end of school, during the summer me and my ex had a double date with my best friend and her best friend. My ex was a whore, she told me she sucked someone off in the school bathroom. I told her I never got a blowjob before, she told me she would on the date. We went to the movie theaters as usual. Me and my ex would eventually start touching each other while watching and we ended up leaving out friends behind and started going to the bathroom together. She pulled my pants down and my cock just sprung up. And she wrapped her lips around it and started sucking. At first I was surprised and later it hurted bc she used her teeth on my dick head, I have thick 7 inch dick. So that’s probably why. She was having issues sucking it to the point she kept gagging and almost threw up, so I took my cock out and jerked it off until I came inside her mouth and she swallowed it whole
