Still, far too long in my book. I am ashamed to admit that I had committed the ultimate sin. I had repressed my sex drive and let work, c***d, family,... etc fill my mind. Only short occasional thoughts had crossed my mind and when they did, I failed to take two minutes out of my day at the office to send a message reminding him how much I desired him. After 2 weeks of near abstinence, he made sure I was clearly reminded of my desire, and his. It was Wednesday evening and I was looking forward to. He asked me how many cards and as my hands started sweating more, I laid down 4 cards and basically threw the game. He laid down two pair and I had nothing. This was it. Sitting cross legged on the floor, he pulled his underwear down under his balls and laid back. Now remember, his sister was still in the room!I quietly moved over to him, looked him in the eyes, then slowly put my head down near his rock hard penis. I kissed it a little, then thought, screw it and put my mouth all the way over. For a second, she was shocked, then amazed, then just wanted him more. Sam was shocked, yet loved it. Sam had pulled his english teacher, of whom he had fancied for months.Sam broke the awkward silence "You're a wild girl, you" he said."Wanna carry on, baby? You'll get an A*" she replied with a sly wink."Come back to the hotel room" Sam said.When they got back to the hotel room, Lisa pushed Sam onto the bed, yet said nothing. She gave him a amazing strip tease, the same routine she had given. I sat there, feeling the sensation of his dick on my back. It was so strange, and my head was spinning. I knew I wasn't gay, but....I never knew I would like the sensation of what was going on. Then he started to rub his hand down my back, and onto my front. Down to my crotch. He whispered into my ear, "I know a way that I can change your mind about sending me that girl's picture" He puts his hand down my shots. He was now thrusting my dick, back and forth. It felt amazing, I didn't want it to.
