Probably because he works as a photographer and isn’t home a lot. But it didn’t seem odd at that time, who cares about their friends’ dad anyway...? It was about 2 months ago, it was a sunny day just like now. The four girls were relaxing at the pool at Emma’s, as she is the only one of them who has pool. When Robert came home. Leah was the first to spot him since Em was in the bathroom at that time and Lily and Jess were tanning, facing the other way. He was looking at the girls trying to spot. She came down to check on my drink. As she bent down to pick up some clean glasses, I could get a nice view of her naked breasts. She stayed bent over and smiled up at me. “What time do you get off?” I said. “I get off in an hour and I expect to get you off 30 minutes later.” She huskily replied. “I’ll be right here waiting darling.” She kept coming down my end of the bar to get clean glasses. Every time she bent over I got the greatest view. My cock was growing in my pants. I knew I was. As if on cue, Christopher pulled out of my mouth and began to spray a heavy load of hot cum all over my face. I opened my mouth to catch as much as I could.Now catching my breath, I saw Jennifer on her knees in front of Julius, stroking his cock, and Gina-Marie was just watching it all. She had her pants off and was sliding several fingers in and out of her wet pussy, with a euphoric look on her face.Julius then walked over to me, rolled me on to my back, pulled my legs up and entered my ass.. He was telling me how happy I had made his mum feel and then a couple of my other mates where there saying how great It was to see all the women getting excited as I stripped and that I should do it for a living, one even asked If I would do it at his mum’s birthday party in a couple of months time.Well I stayed out the back for about an hour as I had sobbered up really quickly and was a bit embarresed about stripping for my friends mum and having an erection at the end that nearly hit her on.
