I ended up in this position with an ex girlfriend one night and have enjoyed it ever since. Now, with my wife.
It was with a girlfriend I was living with back when I was around 25 or so. On that first night, she had already gone to bed. I soon afterwards joined her. I laid next to her and started fooling around a little and it didn't take long for me to get in the mood and I became hard as a rock. I then slid a hand up her nightie between her legs and then I hit it. Instead of feeling a pussy through her panties, I felt a pad. I knew what this meant and she looked at me and said 'Sorry. That time of month again'.
I knew that thing was out of commission so I was then hoping for a nice hand job or something. I was laying on my right side besides her when she reached down and started playing with my dick through my shorts. Her hand felt so good touching me and I laid there and moaned. I then took off my shorts. She shifted some and ended with her left leg laying next to me with her knee bent. She then laid my dick on the inside of her leg and started rubbing it there. It felt fantastic against the soft flesh of her inner thigh. I told her not to stop and that it felt so good there.
I then ask her to put some lube there. She got the gel and coated her hand, my dick and her inner thigh. She again went back to rubbing my dick there while also gently stroking on it. I couldn't get over how wonderful it felt. It wasn't long and I could feel that orgasmic feeling start to build in me and I told her 'I'm going to cum. Oh, it feels good'. Soon afterwards, I pumped a very nice load of cum on her inner thigh as I went off. It felt fantastic. She ended up getting in the shower to clean off all the lube and cum. I was very well satisfied and told her 'We'll have to remember this. That felt so good'.
Well, I've remembered it ever since. Girlfriends I've had and now my wife. This position never fails to get me totally aroused and I always cum off very strong.
