When I was 21 I had two female friends that would come over and hang out with me. I was always interested in one of them but not the other. I never considered her great looking. So one night they joked around asking if I ever masturbated and if I would for them.
At first I thought they were joking and said no, even though the idea turned me on. So the next time they came over they asked again, this time I said yes. So here I am, a guy who would could and would never admit I masturbated, standing there completely nude and masturbating in front of one very hot chick and one ugly one. I was jacking off so hard I am sure my balls were bouncing off my ass while they both watched. I was so turned on I made it last even bending over and masturbating so they could se me from behind. They even asked me to sit and spread my legs so they could see my balls as I jacked.
They asked me if they could see me shoot, so I started to jack real fast and shot a huge load that they even said they never saw so much before.
Now I wish I could do it again, even go to a sex club or party and just masturbate for a group of people. Would love to even post pics of myself going at it.
