Wife's step sister part 2

[Alienowl]

Well this is another occasion when my wife and I were around at her dad's house. It would have been about 3 years ago during summer. It was a very hot day and we had gone around to her dad's house to use the pool.

We had rung her dad and said that we were coming around for a swim. He told us that no one was home and that everyone was out till late in the afternoon but to let ourselves in and enjoy the pool. We got there around midday and grabbed a couple of drinks and headed out to the pool. We just relaxed and cooled down. After a little bit of time we were swimming and both of us were getting a little horny and we started to kiss and play with each other while we were in the pool. My wife was tugging on my cock and I was extremely hard. I sat up on the edge of the pool and she swam over. She pulled my bathers off and while I sat on the edge of the pool she began sucking my cock as she floated in the water. This was really hot and a turn on as we had never done anything like this at her dad's place.

While she was sucking my cock I looked towards the house and saw the blinds move. Someone was inside looking at us. I saw the blinds open a little more but couldn't see who was in there. I didn't let on to my wife what was going on because she would have stopped not knowing if it was her dad, her step mum, step brother or sister. I got so turned on knowing someone was watching.

Was it her dad watching as his daughter sucked my cock. Was it her step mum looking at my cock and my wife's lips wrapped around it. Was her step brother watching her do her wonderful work on my cock imagining it was his cock in her mouth, or was it my wife's step sister watching my cock getting worked on. I didn't know and that was even hotter.

I decided to tell my wife to hop out of the pool so I could fuck her. I positioned her on all fours and slid my cock into her very hot and moist pussy. I positioned her so who ever it was inside could get the perfect view of me fucking her. I was so turned on and so horny being watched I was slamming myself deep into my wife, shoving my cock in as deep as I could and my balls slapping against her pussy making my wife cum over and over. When I was about to cum my wife made me pull out and she turned around to suck my cum from my cock. I shot a massive load into her mouth and some over her nice big tits. She used her finger to clean up her tits and put my cum into her mouth. I then lent over and kissed her cum filled mouth and then licked her tits clean. My wife then jumped back into the pool and I decided to go inside to the toilet, still naked.

I got up and started towards the house and I saw the blinds close. When I got inside I couldn't hear anyone so I went to the toilet. I was washing my hands in the bathroom when I turned around and there was my wife's step sister just standing there. She must have come home from work early. I was still half hard and she was looking my naked body up and down. I didn't bother covering up, what was the use. I asked her if she liked the show I gave her with my wife. She went red and looked all embarrassed. She said that it looked like we had fun. I said it was even more fun knowing someone was watching. She then moved a little closer to me and said that she liked my cock. At this point I got hard again. She was fully clothed but moved closer and grabbed a hold of my cock and said that she had liked how I had used my cock on my wife. She then let go and said she was going to get changed to have a swim and that I should go back to the pool.

I was so turned on by this I headed back to the pool with my cock standing to full attention. My wife said was I ready for seconds and I said of course, but I knew it wasn't going to happen just then. I jumped into the pool and swam up to her and started kissing her. About 5 minutes later my wife's step sister came outside and yelled out to us. My wife got a little flustered and quickly put her bathers on and grabbed mine and gave them to me to put on which I did. Her step sister jumped into the pool and came over to my wife and gave her a big hug and said hi and then did the same to me. She then made out that she had just got home and came out for a swim and saw us. Nothing much els happened that day.

I told my wife what had happened when we got home. She got very horny at the idea that we had been watched and not knowing who. We fucked each other senseless, the whole time I was thinking about her step sister and both of us came again and again.

Can't wait till next time
