“I’m not to sure about this Nan, what if Mom catches us?” “She will be in town till at least five so we have plenty of time. Now let me have ... lick at that hard cock of yours” My cock was not big since I was only 15 and there was very little pubic hair to hide my balls. When it got hard it was about 7 inches and the head was always sort of a purple color as a whacked off often. Nan knelt down in front of me, gently stroked my shaft and balls. Having someone else handle your cock is sure. Her cunt with its dark brown landing strip bouncing above his head, our breasts bouncing into each other as we kissed. And when he looked down my lips and clit were wet and throbbing, sliding up and down as the head of his cock was disappearing again and again deep inside me.

I froze for a moment, listening for any change in Jane’s gentle snore, but it didn’t stop and neither did we. Sarah came up. Sorry,I felt a desperate need to type it like that.I started looking for a way trough the waterfall,and found her clit.Gently massaging it,and her pussy,she stopped sucking.She was cumming?Hell I wasn’t!Over the years I had grown some endurance.She took a breath.“With that thing in my mouth I can’t get air.”She went on as did i.As we both ,knowing we couldn’t hold longer,announcing to eachother we were gonna cum.The door opened.We were terrified,if I wasn’t in my sisters mouth,I would piss my. Wow, I didn’t expect that day could be a luckiest day in my life.Her fingers were playing in my neck, between my hairs and head by the name of massage.

I started working on her system again, I opened the Internet explorer and was fucking shocked to see the history. It was all porn websites that she has visited. I thought she was a very good girl all these days. She came back with some sweet that she prepared.
