Well this happened about two weeks ago. I was at my my girlfriend's friend's house and we started to get a little horny. I told her that I was gonna go someplace and 'take care of it.' Well I went into a seperate room and pulled my penis out of my pants and started to stroke it. After a while I was expecting my girlfriend to come in to watch me. I heard the door open and just continued, until I heard a loud 'OH MY GOD.' I quickly turned around and saw it was my girlfriend's friend. She ran out of the room and I still had my penis hard and out of my pants. After a little bit I got back to my business and finished up. I got back and sat with my girlfriend and her friend, who were just sitting there watching TV. I wondered if anything had been said.
I left and came back the next week. My girlfriend pulled me aside and said that she knew her friend had caught me. I was thinking I was gonna get in trouble with her, but then she said, 'she wants to have a masturbation session with us.' I was really shocked because I had imagined her friend a couple of times before when I masturbated. When we came back into the room my gf nodded her head to her friend and told me to sit across the room, so I did. As I crossed the room I grew one so fast and hard. We just sat there and stared at each other for a while, until my gf unzipped her pants and pulled them down revealing her nice shaved juicy pussy. She started to rub herself. I was so hard. Then her friend pulled down her pants and panties. Oh my god, what a sight. Two women just masturbating in front of me, so I pulled mine out and decided to have some fun of my own.
I started to stroke it gazing at the two wet nice pink pussies. Her friend's eyes just staring at me, then my girlfriend's. My girlfriend started to breath heavier, heavier and heavier, then BAM, she came. Next her friend came and they both just stared at me. I was pumping so fast lying back, they got closer to me and I shot so much cum all over the two of them. the friend was kinda shocked at first and then she accepted it. We all went to the bathroom and cleaned up. I kissed my girlfriend and then kissed her friend on the cheek. We went back to the room and her friend thanked me, then I thanked her. After a little bit of small talk we got horny again, so we did it again. Man it was so good. I'll keep ya posted if somethin more happens.
