Luckily her bathroom door was not locked, so I quickly moved into the bathroom to check on her and there she was lying on the floor naked. I was shock...d by seeing that sight. So grabbing my opportunity, I lifted her naked and slowly took her to her bedroom. I made her lie on her bed. She was crying with pain as her back was hurt. So I took a pain relief balm and started to apply to her back. After some time, she stopped crying from pain and started to moan with pleasure. She then took my hand. Later that night my parents said that they were going to go out and have some drinks with some friends and wouldn't be back until about midnight. Instantly I thought that this was going to suck as my sister wouldn't have to hold back on her outfits and the teasing was going to be much more than I have experienced thus far. As soon as my parents left my sister disappeared into her room for about 15 minutes before returning to the living room. As I thought she was in just a black thong with a. John, this is my friend Amy, and I see you have met her mother.”“Hello, Sir. Wow, you sure are lucky, Annie. I sure do miss my Daddy, and Mom hasn’t found a new one yet.”“So, did you have a ‘special’ relationship with your daddy, Amy? Like the one that Annie had with hers?”Amy blushed bright red and nodded.“Hey Amy, don’t be embarrassed. Mr. John knows exactly what our daddies meant to us.”“Annie, are you disappointed that we have company this afternoon? Didn’t you expect to have me all to. I couldn’t help but look at his hardening cock. It was about 6 inches, thick and cut. He walked over to me a stoked my cock. It was like an electric shock through my body.“Look I’m not gay,” I spluttered.“Your cock and the look you gave me would give a lie to that.”His hands were now around my waste and he was pulling me towards me. Our cocks crushed together. His hands stroked down my back and around my arse. My head was telling me to push this guy away but my body was telling me to let him.
