I was invited by the busty, slender, and muscular, sexy wife next door to train with me! It was supposed to be a healthy exercise, but I got an erection from the temptation of close contact... I gave her a handjob while working out, and while training my lower body, I had a pounding cowgirl position, and had sweaty adulterous sex full of sexual desire! I couldn't resist the pounding piston that squeezed my dick with her abdominal muscles while breathing deeply, and I came inside her many times! I pushed her to her limits with her big ass and had sex to relieve my sexual desire, and my dick got sore!
