It took a while but I eventually pushed my cock into her oh so tight arse. after a couple of mins she loosened up and I was able to go balls deep in h...r she was laid on my stomach and I was gently pumping her arse while I had my right hand round the front of her fingering her pussy. I rolled her over and made her go doggy style and pushed my cock up her arse again she whimpered in pleasure as I rammed it deep . I worked my way up and let her have all my sperm up her arse . As I was pumping. I put my head back, closed my eyes, and gave him a moan of pleasure as he slid two fingers into my very wet, very slick hole.He was working them in and out in his driveway, in the daylight and I am sure if anyone was watching out their windows they would wonder what he was doing there kneeling next to me with his arm moving. Then of course add to that my head being laid back, well I am sure you can imagine as I sure did that we made a very naughty picture.Terry began to work his thumb on my. That’s when I almost shit. Eric moved up and his cock went up the back of my tee shirt. It felt as hot as boiling water. He kept jerking off on my back and running his hands up and down my hip and onto my cock. I started to throb after a while and his hand didn’t really bother me. Then I felt him spasm and he grabbed my chest and held tight. If you’ve ever been humped by a dog you know the feeling.When he was done he stared to loosen my belt. I let him do as he pleased. His warm hand felt good. “Daniel! We’d almost forgotten you were here!” she said.“How's that for 'sex education' champ?” Mark asked.I was speechless.They laughed together at my response and kissed for a short time longer. They whispered something I couldn't hear, and they got up.“We’re going to take a shower now,” mom said. “Afterwards we’ll cook up a nice meal.”They walked out of the room, arms around each other as lovers.My heart was beating rapidly. I had literally just witnessed my mom and uncle have incest sex in.
