Since my parents did not let me or my sister have TVs in our bedrooms I was forced to head downstairs. As I turned the corner into the living room how...ver I noticed that I was not the only one who was having trouble sleeping. I saw my younger sister Tara laying on the couch. At first I could not see what was going on but as I got closer my jaw dropped. Tara was masturbating, and I mean she was really going at it. I knew that I should leave but I couldn't. The room was dark, so I moved quietly. We'd already planned ahead and we'd put some explicit, well-chosen pics of her on my phone, I handed it to him and he went through the gallery one by one, his chin nearly hitting the floor! He'd known her for years, longer than I had in fact and here she was holding her pussy open and fucking herself with her fave toy in full HD!. My throat was dry and my heart was pounding seeing him looking at her like that, but wow, was I turned-on, he could see what a sexy little bitch she was for himself. It was such beautiful smell. Now she was holding my dick and started playing with it. She was cuddling my balls and god it was such an awesome feeling.I started to lick her cleanly shaved cunt and in turn, she was kissing my dick. Guys, it was a perfect 69 position that we were in. Now I started to bite the lips and she was moaning heavily. She became restless and started to take my dick completely inside. She is soo good in blow job. I was in heaven. This encouraged me to explore the pink love. My cock slipped out of Caitlin’s pussy, but she whisked a pillow out from under her head and slipped it under her hips so I could enter her again. Before I could start moving again Rob pushed my legs a little further apart so my hole was fully exposed. I felt something cool and moist flowing into my crack, and then Rob’s finger spreading it around and into the hole. I gasped, and my cock must have stiffened a little because Caitlin gave another little whimper of pleasure.The next thing I felt.
