sharing Mendy

It was a hot summer day, my long time girlfriend, Mendy, was over for the weekend. We had just gotten back together. We have broken up many times before, mostly because she likes to fuck other guys now and then. She was pulling weeds from the flower bed and I was mowing the yard. I was watching her ass more than where I was going. She has a sweet little ass and you could see the outline of her pussy through the tight, thin material. I saw her go into the house and I jumped off the mower and followed her in. She was bent over, looking in the fridge. I came up behind her and grabbed her hips and ground my hard on into her ass crack. She stood up and turned around. I grabbed a handfull of that ass, her tit with the other hand and kissed her. “No”, she said, “I am all sweaty and dirty.” I didn’t care, I was horny and kept up my assault. I slid my hand into her bottoms and found her pussy. I slid a finger in it and rubbed her clit a little. She said “no” again. “But I’m horny and want you now.” She slid to her knees, undid my shorts, and pulled out my dick. She gave it a little kiss on the head, her lips felt so good. Mendy then looked up at me and said “I’ll give you what you want now, if I can have what I want later.” I couldn’t wait to have those lips all the way around my head and would have agreed to anything. “Ok” I mumbled.
Mendy was a great cock sucker and had me bucking and moaning in no time. She grabbed ahold of it, put her mouth around the head and swirled her tongue around it. I grabbed the back of her head and picked up the pace a bit. Her firm grip on my dick and wonderful tongue soon brought the tingling feeling to my balls. My dick swelled and I pulled her in till her chin was against her fist which now had a death grip on my cock. My toes curled and I blew my wad. Mendy went to the bathroom to spit, as she normaly does. When she came out I ask her if she wanted hers now. She said “nope, you said I could have what I want. I want to go to a bar, pick up a stranger and fuck him in front of you. I know it’s your fantasy to watch me fuck someone.” My heart sunk, but my dick got hard again, she was right. I always wanted to watch her fuck one of those other guys.
Mendy was looking really hot in her little black dress and off we went to the bar.
