Something is better than nothing so I decided to go for it.I took his hand, put it on my crotch area .This was all he needed he started touch my cock ...igorously and couldn’t able unzip my jeans so I unzipped my jeans he immediately started sucking my cock so hard and roughly I could feel his teeth at first tried to stop but I couldn’t.He pulled down my jeans I was technically naked now he didn’t stopped blowing. His warm mouth and cold night made me horny. I was enjoying his rough blowjob but. There were two bathrooms, one common and one attached with the master bedroom as there was bath tub in the attached bathroom.I usually use that and so in the shower I was masturbating around 12:30 when I was taking shower and my sister came back from job as she was not feeling well because of head-ache. She was not aware of that I am back from college early and even I was not aware that she came back early.She came into her room and unzipped herself and became naked at that time also she did. She was moaning in pleasure and pain…ahhhh….ohhhI sucked those melons for 10 minutes.After that we both became naked and she sucked my cock for 10 minutes….I was about to cum but I didn’t wanted to….So I stopped her,and hugged her tightly,her boobs were pressing against my chest,In the mean time I saw her ass while hugging,so I squeezed it and spanked it while talking to her,she was stroking my cock.All of a sudden I pushed her onto the bed,spreaded her legs,,,,those thighs were jiggling due to. " Normally I would have picked her up and swung her around, but with four stitches in the arm I didn't think that would be a good thing so I set her down and gave her a hug with my good arm. By then the other two had noticed me and came running over. After a minute of hugs and kisses I asked:"Where's your mom and Uncle Herb?" In the back playing."I took that to mean they were in the kitchen playing cards. I let the girls go back to the TV and I headed for the back of the house where the kitchen.
