Fortunately ive always been blessed with amazing stamina and control but i have had a few cases where i blew my load embarrassingly quick.
First one that comes to mind
I had just broken up with my GF, things had been rough for months and the sex was really the only reason we dragged it out and that had even become boring and unsatisfying. There was this woman she knew that had a not so secret thing for me, Blonde hair blue eyes big tits and a big ass total knock out, no surprise she starts texting me within days of me being single, i knew we would hook up sooner than later, she tried getting me out to the bar on the weekend but i talked her into coming to my place. We both knew how the night was going to play out, we put on a movie and almost immediately started fooling around, we fooled around for probably 20-30mins, i was already nervous about cumming too soon so i grabbed a thicker condom, put it on and she started riding me cowgirl, i blew my load in minutes, i was a little embarrassed but told her i couldn't help myself, she was cool about it, we started going at it again and i was able to redeem myself.
Second time that comes to mind
A FWB had recently finalized her divorce, we had an affair and had become very familiar in bed a few years prior, she always joked that aside from my size she kept sleeping with me cause i could go for a long time and always get her off. We had reconnected and she started texting me one night that she wanted me to come over, unfortunately i was busy and couldnt but that didnt stop her from sending very sexual texts and pictures in an effort to change my mind. The following night she was at it again, she was staying at her parents though so she wanted me to come pick her up, she told me to drive to a park down the road, she gave me road head as we drove, we found a spot with some privacy and we both got in the passenger seat, she slipped her pants off and straddled me, now we had always wore condoms to conceal the evidence, i hadn't had sex in a few weeks so when she decided to take me bareback i knew i was done, i manage only a few thrusts before cumming, that time i wasnt overly embarrassed, she knew i was good for more and we ended up returning to her parents and going to their barn, where we fucked several times before calling it a night.
Shit happens, no point in worrying about it.
