%100.00 true story
One summer, my parents went out of town for the weekend to visit old friends of their's. They didn't trust me in the house alone so they stuck me at my neighbor's. My neighbors had two kids, both girls. One was married and moved out, the other was named Emily, she was 17, only one year older than me.
One night when I was there Emily's parents had gone out to dinner, and Emily was having her friends Jessa and Katlin sleep over. My guest room was right next to Emily's room. I had always had a crush on Emily, and had often thought of her when I was masturbating.
I was laying on my guest bed, bored and thinking about masturbating when I heard all of the girls laughing. I wondered what they were doing, so I decided to go see.
I leaned my head out of my door and peaked around the corner. To my amazement they were all sitting on the bed with their hands in their pants rubbing their clits. I wanted a better view so I leaned foreward a little bit, but as I steped down on the wood floor the floor creaked. Emily and her friends quickly looked up, probabaly afraid I was Emily's parents coming home from dinner. Jessa and Katlin giggled, and Emily smiled at me. She said 'Hi Sam, do you want to come in for a better view?' I thought 'Hell yes!' I told her 'uh, sure.' I was so nervous I had never seen girls masturbate live before. Sometimes I looked at my parents porn videos that they had bought when they were younger, but that seemed like nothing compared to this.
I walked in and sat down on a chair in her room. Emily turned her head and smiled at her two friends and then looked back at me. She said 'We'll masturbate in front of you, if you do in front of us, and then cum on our belly rings.' I decided to negotiate a little bit 'Okay, only if you take your tops off.' The girls agreed and started to un-botton their shirts. I was actually feeling more comfortable. I pulled down my pants to show them my 6 inch cock. Jessa said 'Its even bigger than I had imagined!'
I slowly stated to stroke my cock. The girls were gradually starting to finger themselves faster. My eyes were glued to Emilys huge 36 C breasts. Katlin moaned 'Oh yes, ah fuck! and started to cum. That triggered all of us. Emily was next 'Oh Sam, Im going to cum, Ah ah ah!' I could barely contain myself. Jessa's back arched and she came hard. They could all tell I was about to blow. I walked over and Emily unexpectedly grabbed my cock from me and started to rub it faster. I shot out all over her, and then Jessa and Katlin. Emily swiped her finger over my cum on their stomach and licked it off.
We never got back together again and did this. Although when I would see Emily sometimes she would lick her finger and smile at me.
