Part 2 described the beginning of my evening and what followed in part 1 of this story so I suppose this has to describe the climax, but where to start , she would cum repeatedly and could easily outlast the man, but for our minds and and versatility for she was not only turned on by her lust for more but to explore new horizons with her husband s lust evidence to see. They had been swinging by themselves and a few couples but this transition to a new reality would change there lives forever. He was straight and she was bisexual, but deep down we all are. We had progressed in earlier visits and had a huge amount of fun and mutual sexual highs, but being somewhat more she continued to explore and so when she had asked if she could fist me I had only hesitated for a second. Or when he had asked about using condoms for anal sex safety I had whole heartedly agreed. From that first meeting to the climax off the story, we did everything possible. She wanted to use a strap on and fuck me , well I did it. In between we fucked her . He wanted to suck her while I was inside her and then to asking if they could both suck my cock together, I became the filling in there sex sandwich, and there is not much we didn’t try, but the most intense orgasm of all only happened while buried deep in her cunt, I seeded her and filled her with my testosterone, each squirt with intensity to breed her. Grrrrrrrrrrrrrrr
