I began to be somewhat suspicious as the noises were now recognisable as sex noises.I silently got up to the door which was open a crack, just enough ...to peer through and identify who was making the noise. I could see my wife’s feet on either side of our friends head. I could also see his arse jerking back and forth as he fucked my wife. The sight actually made me hornier, which I would have thought impossible earlier on. I stood there for about five minutes with my brain flashing all over. Was she just picturing Mark's penis... slipping in and out of her... No, he was her friend, she wouldn't think that!But damn, she was wet. She hadn't realized it, but ever so slowly she had been getting more and more turned on by this. If she didn't take care of her arousal right away, she might do something unwise with the big penis staring her right in the face.Turning to her bedside table, she reached into the top drawer and pulled out her trusty vibrator. Mom was one of those people who. I don’t really know how long it lasted, but I worked his cock over for quite a while, as he pinched my nipples and fingered my throbbing pussy. He lasted a while himself, but soon I could feel his cock throb and swell, and his finger on my clit was bringing me close to orgasm myself. I began gyrating my hips and sucking harder. He moaned he was coming and I couldn’t stop. It felt so good sucking him I had to taste it, and I sucked down as far and hard as I could and let his substantial load. He asked me if I had ever had sex with a man before. The water helped and I said no. I confessed my curiosity and Andy seemed to relate to my confusion. I pulled my pants up and we kept talking. An hour had past since we closed. We talked about our sexual desires. Andy told me to make a list and he would make one too. We would exchange them and see what we had in common. Before leaving, I asked him if I was weird being attracted to male and females. Andy said it was perfectly OK to be that way..
