Fondling my sleeping NOT sisters feet

Now bare in mind there's been a countless amount of situations like this that has happened before and after this, but this was one of the hottest ones. One of my sisters used to lie down near me a lot and rest her feet near my cock. I know she knew that i had a thing for her feet but she never confronted me about it. Hell, once she caught me licking my hands after massaging her beautiful feet. Didn't say a thing. Well one time it was just me an her in the house watching a movie and she was lying beside me with her feet getting closer and closer and eventually she asked for a massage. Just the thought gave me a hardon at the wrong time. She rested one leg on my crotch while i massaged the other. A little later she fell asleep and a nudged her to make sure. She was asleep. My beautiful sister lying there ass stuck out, feet on my boner.. I was so damn horny. I took out my cock and it felt sooooo good against her bare feet while just lightly touching her salwar covered ass. I then grabbed both her feet and rubbing them up and down over and over. I first thought, have some fun then go to the bathroom to jack off, but i couldn't stop and moments later i exploded and came all over her feet! It felt so fucking good! I was thinking 'shit! What do I do with the cum? Do I wipe it off?' But I didn't. The thought of my sister laying there with my cum over her feet was too good of a thought to ruin.
