My FWB wanted me to milk him out of cum dry while sitting on all fours...

I was at my friend's house one summer night we got bored and decided to watch Fifty Shades of Grey.

He said he had never seen it and I wanted to see his reaction really bad at it since I've seen it more times than I can remember. While we were watching the movie I could see from time to time a bulge in his pants that was pulsating and I even rested my hand on his thighs to see what he'd say.

He was rock hard for almost the entire duration of the movie and even tried to hide it with his hand but it didn't work. At the end, he asked if I could help him with something since he hadn't had sex in quite a while. I thought he wanted to fuck me hard but no, he wanted the opposite.

He wanted me to milk him dry out of cum while he was sitting on all fours on the floor and getting his ass eaten. I was soo horny at that time that I decided to go all in and play his game and just like that we were on the floor.

I was eating his ass, jerking him off, and with my other hand playing with my pussy.

The entire time he was moaning as hard as a girl and came on the floor 5 times in a row until he was shivering soo bad that he didn't have any more cum in him.

By the end of our milking session, I dipped my hand in his cum and licked some of it.

I think I'm a good friend for helping him.
