The short version...I was hanging out at my parents house after a big pool party. The two young girls that were friends of my stepmother (she actually used to babysit the one) were 19yrs (black hair looked gothic) and 20yrs (blonde hair). They were wrestling around in there bikinis which made the ones nipple slip out of her top. It was obvious that I was staring. I did not tell her about it and she never fixed her top. I instantly got a huge boner. I tried hard NOT to hide putting the bulge 12-18 inches from her face. I had been perving out on the girls all night looking hard at them especially the black haired girls chubby body in her transparent white bikini. I was mesmerized by the camel toe she wore. It was very obvious she had no pubic hair and had puffy pussy lips that devoured the swim suit.
At the end of the night I took the group for food. The dark haired girl went back into the jacuzzi and the other girls stayed in the kitchen eating there fast food. I said goodnight and ran off to seize my opportunity! I knew that the spare bed room had a sliding glass door that opened to the pool area. It was perfect for viewing the slutty teenage girl. I was so hard! I knew from before that at night when the lights are on in the bedroom you can NOT see outside and the outside view looking in is awesome kinda like a spot light effect.
I looked at the young girl get in and out of the jacuzzi. Her bikini was soo small and her ass was hanging out the sides of the bikini. With the lights off I started stroking my hard cock for five minutes. then... I had a plan. I turned on the lights and made as much noise as I could and pretended that no one could see me. I took my shirt off and walked closer to the sliding glass door. I pulled off my swim suit and pulled my shaved cock out slowly putting on a good show. I was standing one foot away from the window which happens to be on the right side of the guest bed. I stroked my cock almost slapping it against the window then stopping the stroking again in between folding my clothes and making the bed.
I could hear her exit the jacuzzi as the water splashed. She was getting a better view. She had to be about one foot from my cock. When I knew she was near I laid on the edge of the bed cupping my balls with one hand and now pounding my cock up and down. I shot one of the biggest loads of cum up my chest then the second shot to my face. I knew she could see me and then I collected the cum off my body and ate it for her. It was like she was in the room with me. I have never seen her again but I can't wait till I do.
