This happened many years ago when I was living with my older sister in California for the summer....
My nephew had joined the Marine Corps and were stationed at Camp Pendleton. Some of his friends were from all over the states so when it came time for leave, my sister opened her house to them so they could have a home away from home.
This one particular weekend we all were hanging out in the living room with our sleeping bags and blankets and partying enjoying ourselves when someone suggested watching some porn. We all said Yeah sure!
After watching several scenes it was obvious that we were getting turned on yet these guys were like family..sorta. lol Finally everyone started to crash out in their sleeping bags including me. The porno was still playing yet I rolled over and tried to go to sleep but i felt sooo horny and started fingering my clit. After awhile the TV went off and the room fell quiet. In the silence I gently rubbed my aching pussy thinking of the porno and the fact that I was in the same room with 5 hot bodied soldier boys! I could feel my excitement increase as well as my pussy cream. I spread my thighs abit wider and really went to town rubbing and fucking my pussy until I came hard. I tried to be quiet and hoped no one heard me but after a minute or two I heard one of the guys get up to go to the bathroom. Maybe he was hard and needed to jerk off? To this day I'll never know if that was the case or which one of "My Marines" it was.
