I was forced to cum in public by my fwb.
I've always had a very sensitive cock, the slightest touch can make me go from soft to throbbing hard in an instant, if the touching continues then my cock will twitch and throb like crazy until I explode before she even gets her hands on my cock.
Whenever I cum from something like that my entire body shakes and it's always the biggest cumshots. One tine I was out at a bar and my fwb was there, she was out with her friends and she was wearing this stunning green dress, it always drove me wild and that night she had this naughty little look in her eye that told me she was wanting to tease and play with me.
As soon as she saw me, she came over and immediately started to touch me, gently running her fingers over my bulge and smiling at me. Some time after, she starts grinding on me as she dances and pressing hard against me, I tried to stop her but she wasn't going to stop, I tightly gripped her waist as she backed me up against a wall and kept grinding, looking over her shoulder with a dirty smile and then it happened, I went past the edhe and started to unload rope after rope into my boxers, moaning into her ear as I did and leaving a huge wet patch that immediately appeared on my jeans.
She took my hand afterwards and we walked to her place where she cleaned my cock and we fucked, I got her back at a later date.
