Margaret sat in the chair between them smiling broadly and waiting intently for the show with Brenda and me to get started on the bed. My cock was alr...ady completely erect by the time I sat on the edge of the mattress and Brenda knelt at my feet. As I spread my knees apart, Brenda spit on both her palms and began stroking my shaft. Her nipples began to get pinker and harder as she pressed her milky white breasts against my hard on and began stroking it between them. She cupped one hand. She was a mother of four, so perhaps a little fluffy around the middle, but had a great set of tits that were highlighted by a tight top. Trying to my best to banish filthy thoughts from my head, I laid down on the table and we began the appointment.She went to work on my quad, starting near the knee, and working slowly upwards. It felt heavenly...I tried to think of just about anything else to avoid popping an erection. As she moved up the leg, she slid my shorts up as far as they would go. It. When I and my gf are alone, we used to have sex in her computer room, and we have a very open relationship. We used to talk a lot about sex, sex games, sex fantasies, and dark fantancies. She always wanted to have threesome with me and her ex-bf. And I’ll always reply her with, ‘Okay, let us have threesome with your sister. Then we can have with him’ and she would smile, and leave that topic. We even used to have sex when her sister is home. We used to keep our doors shut, and have a quality. That was the first, and certainly not the last, night she did not coax his dick to some ressemblance of erect and attempt to satisfy herself. She shuddered involuntarily when he place his arm aroung her, placing his hand safely just over her bellybutton. Though she felt repulsed she even managed to twist around to give him a kiss good night.That next day she did something she thought she would never to, ever. She violated his privacy to find out just what the stranger that was her husband.
