Because we'd flirted so much over the past six months, when we decided we'd take the risk and have sex, it was extremely rough dirty sex. From me licking and tonguing out her pussy and ass, whilst fucking either hole with a dildo she had. To her probing my asshole deeply with her tongue, before I fucked her mouth pussy and ass in any position we could think of. It was as I was fucking her pussy from behind, at the same time screwing her asshole with the dildo, that her son, my best friend walked in.
The air could have been cut with a knife when we eventually saw him, as he'd watched me pumping my cock in and out of his mother. But it was only when he moved did we see him, and by then it was too late for me as I came deep inside his moms pussy. Turning around he called us a few choice names and walked out. Not one to miss out on a sexual chance as I've come to find out, his mom said "Oh well he knows now, might as well enjoy ourselves". I spent the next half an hour making her climax, by licking her pussy clean of my cum, and then she had me fuck her asshole once I'd become erect again. What I and my friends mom didn't know, was her son watched the whole thing.
The way I found out was a series of texts he sent me that night. They ranged from anger and my demise, to understanding why his mom would want and need sex after so long without a guy. The final text before I drifted off to sleep, was him telling me he forgave me. My reply was informing him just how embarrassed I was.
Three days later I got a text from my friend telling me his mother would like to see me. It turns out they'd spoken and it also turned out, and I'm still not fully understanding why, they'd agreed she should have someone to have fun with.
So feeling really really unsure the next day, I called by my best friends home. He invited me in, but said he was going to visit his girlfriend. Leaving me alone with his mom, she couldn't have been more calm. Taking me to her bedroom, we had sex pretty much the whole of that afternoon and into the evening. We were still fucking when he got home, and as if nothing was out of the ordinary when we eventually walked downstairs, he got me a beer as we sat and chatted about baseball, golf and his new girlfriend.
Now most days if I'm not working or indeed sometimes after work, I find myself between my best friends moms legs, fucking her pussy and asshole for all I'm worth.
