Years ago I used to "stud" for couples. Mostly married couples but some were just kinky bf/gf couples. Most of the time in those situations its because the man in the relationship is small and and wants to see his woman with a hung dude. anyway, most of the time its NOT hung guys. but once in a while it would be a couple where the guy IS hung and they just want to give the woman a fun experience w/two hung dudes. anyway, me and this other hung dude did NOT mix well. I could tell he had an attitude that I was bigger (he was used to the attention on him). As we talked and took turns fucking and pleasing his lady, I bet him I could make her cum in less time that he thought his quickest time was. She said "probably" around 5 minutes. We bet $100 and, and on top of that his girl said we should make it interesting if I won, he'd have to suck my dick. If I couldnt make her cum in 5mins or less, I'd have to suck his. Neither of us wanting to back down in front of her, we both agreed. I was nervous as fuck because if I knew if I lost this mouthy mother fucker would relish that I had to suck his dick w/his girl watching. Lucky, the chic was so turned on she came damn near immediately - like less than 3 mins lol. So sorry to ramble, but yes, I did have a dude suck my dick. He wasnt any good at it but it was satisfying that he was talking shit most of the night and then had to have my dick in his mouth with his girl looking on.
