Maried Male Friend

I was never particularly picky when it came to sex, men or women would do fine. And since I was unattached, I didn't have any trouble hooking up with more than one person at a time. I didn't have trouble hooking up with married people either. When I got separately involved with Adrian and Gwen I didn't realize they were married. Not that it mattered. I figured they were just cheating on each other.
That was fine. But then I found out that they had an open marriage and Adrian had a special secret he was even too ashamed to tell me.    ADULT READERS ONL Originally published in three parts. This 30, 000 word novelette contains explicit sex and sexual descriptions. It contains straight and gay sex, group sex, male chastity, cheating spouses, and sexual humiliation, along with descriptions of sexual activity that not all readers will enjoy.
All characters are 18 or older.  Excerpt: Gwen kissed with that urgency I only saw in a Hollywood movie or when I was meeting up with a woman who was cheating on her partner. Maybe she was unconcerned to be cheating. Maybe it's what really got her off and not the actual sex. Maybe she had an open marriage. I frankly didn't care and neither did she, otherwise she would have taken some care in hiding her wedding band and large diamond ring. "You in a hurry?" I asked as we moved through the hotel door and into the room I had rented for us.
Making out in the hallway was fun, but it could only go so far before we ran the risk of getting kicked out of the hotel, room rented or not. She shook her head at me as she opened the buttons to her blouse. Her fine blond bangs swung in front of her crystal blue eyes. "Not in a hurry, " she said. "Just eager." She approached me again and I reached inside her blouse while her hand groped at me. Underneath her soft blouse I could see the lacy bra she was.
She was eager.
