Big Boobs Brunette in White Pantyhose In Public

My wife had been going out every Friday night with her sister for a few months. At first it was good, because she always came in feeling horny, I think she was getting chatted up a lot and it turned her on and I got the benefit. Then the horniness stopped and she just slipped into bed beside me when she got home and wouldn`t let me touch her……I wondered if she was getting it before she came home.but surely not my lovely wife.
Any way one Friday I was awake when she got home, I chatted to her as she got undressed, I couldn`t believe my eyes as she peeled her skirt off and bent over, there was a leaf on her calf under her tights…..this only meant one thing…….her tights had been off tonight, outdoors.
I said nothing about, knowing she would never admit it if she had been screwing around. The next Friday, I followed her. She picked up her sister, and to my surprise her sisters Husband. They headed to town and into a bar for an hour or so, then drove to a car park at a local picnic spot. I parked in the lane at the side and crept into the car park. There were three other cars there. I watched as my wife got out of the car crouched down and was joined by her sister who got on her knees beside her, her husband appeared with his trousers round his ankles and my wife started to greedily suck his cock, it was no bigger than mine but she seemed to like it a lot. Her sister joined in and as they took it turns to suck it 2 other guys came to watch from the other cars.

I could see my wife had her hand in her pants and was playing with herself while enjoying the cock she was eating. The two guys were wanking furiously and enjoying the show.

Next the two girls stood up and took their knickers off and leant against the car side by side with their bums sticking out, legs apart. Their knickers were just lying on the ground and her sisters hubby just grabbed my wifes hips and rammed his cock right into my wifes pussy, I had drifted closer and heard her groan with pleasure, I couldn`t believe it as he started to fuck her, she complained as he pulled out saying shee needed a cock in her. I was stunned when he pointed to one of the guys and gestured for him to do the honours. He came forward and I saw he had a monster of a cock, I wanted to shout out to stop, but couldn`t, then when he slid his cock into my wife with no condom I thought she would pull away, but no, it made her go wild. He plunged his huge cock into my wifes pussy as she yelped like a puppy, I saw him make three hard thrust and I knew he was emptying his balls into her as she came magnificently.
