My girlfriend Carla and I went to a party, at her friends big house in the country, there was a lot of family friends and strangers to us, but things were going fine, lots of drinks flowing, lots of nice food, some nice music and lots of chatting.

Carla had been dancing most of the night, including some slow dancing with other guys, and I had noticed a bit of wandering hands at times, but she can look after herself, and knows I’m there if she needs me, so I didn’t intervene, as she seemed to be enjoying herself.

Then I saw her disappear out of the patio doors so I thought I’d go see where she had gone, as I got up to the doors I could see dark shadows by the summerhouse. So I looked through the side window and could see Carla kissing some guy, and she looked as though she was almost feeding on his tongue, and she looked very worked-up, and I could see the bulge in his shorts.

Almost immediately Carla used one hand to undo his shorts, while the other was behind his neck, pulling his face to hers. His shorts dropped to the ground and his cock was popping out the top of his boxers. Carla then nuzzled his neck and then slowly worked her way down his chest with little nibbling kisses, pausing for a few moments at his nipples – her hand never left his cock. I had an excellent view, there they were, not 10 feet away from the window with the full moon providing enough light to see what was going on.

They were sideways to me, so I could see their profiles well, then Carla paused, cleared her hair from her face, and planted a sloppy wet kiss on his cockhead, then she kissed him right down to his balls, with her little tongue, then sucking kisses back up his cock before sucking the head into her mouth. She was sucking on his cock, both hands on his ass pulling him forward, as if his thrusts weren't feeding her fast enough. Then she backed-off his tip, and I could see her tongue swirl out under his cock head, before engulfing it again swallowing his cock.

After a few minutes of this, she pulled her head away, looked up at him, and reading her lips she said "I need you in me ... now!" then she stood up, never letting go of his cock and kissed him again and lifted her skirt to show him she was pantieless. So he got on the decking pulling Carla down on top of him, and Carla knelt down with a leg either side of him and lowered herself onto his cock, and my cock was so hard I thought it was going to burst through my trousers, an I was just hoping nobody would see.

Her ass was toward me, so all I could see was her hair flinging around as she sat down on his cock, grinding her pussy as tight as possible against him on each down stroke. I could see his cock glistening in the moonlight, as he was sucking and kissing her nipples. His hands were on her ass, grabbing each cheek pulling her downwards with each upwards thrust, then he continued to pump her again, with his head buried in her tits and hands pulling her to him.

Carla’s beautiful black ass was totally exposed, as he was still grabbing her ass. After a couple of minutes of this Carla started moaning loudly, and I could hear her cries, as she started cummin and he thrust his cock upwards and held her to him, obviously as he was filling her with his cum. Then they must of sat that way for a few minutes, his cock had softened, and popped out, and as she half straddled him, his cum leaked from her pussy onto his thigh. They then got dressed and Carla walked back in on her own, and saw me over by the window, and gave me a smile and a wink, before she continued dancing, and I wasn’t sure if she knew I knew, but I can’t believe how hot it was watching her.
