I mean soon after you started to masturbate I saw you do it. It was amazing watching you. Of course I often saw you naked but watching how you fuck yo...r pussy was so exciting... I started to spy on you more often. When I jerk off I think of you fucking yourself. I sometimes even pretend to be your dildo. I hope you are not going crazy about that... I am sorry...”He went bright red and looked to the floor.“You did what? This is so wrong... I... I am your sister...”“I know and I am sorry but. .. Few minutes later I get a picture of a dick! I'm like whoa! Wasn't ready for that. I text back why not send me a picture of your face? I didn't get an answer. I waited for an hour horny as hell. Kept looking at the dick picture. I laid on my bed and started to masterbate.My phone rang! I was startled. I answered and it was Phil. This was the first time hearing his voice. I was laying on my bed playing with my pussy. He asked me what I was doing and I told him. He said, take 2 fingers and put. As he headed back to the table, he scouted the room. Her eyes followed his. With one or two obvious exceptions all the girls seemed paired off. He sighed as he sat down, reluctantly joining his buddy's research, but obviously not giving it his whole attention. His eyes continued to check around the room at regular intervals.But he hadn't seen her, alone. He hadn't seen her watching his sensuous mouth as he sipped his beer, or the way his muscles rippled as he reached for something across the. Anyway, back to the story. She looked at me with a wink and said sweetly with a hint of animal lust “Okay, you asked for it, now take it.” I quickly, but a manly as I could, walked around behind her. I could see her slit and clit waiting for to be stretched and properly pounded. I took off my shirt, moved up behind her, and rubbed her firm round ass. It was a great feeling as I gently massaged her bottom and got a great view of her back. Then as she looked back at me I kept my left hand on.
