My s*s Anna is older and more chubby than me so I think Robert appreciated the difference.I went for a swim. First it was just me in the water and aft...er 20 min he came to cool himself down.I swimmed on my back with my legs spread so he could have a good look of my young body.Few times we were swimming closed together and I know he was hard when he touched me in the water. I know he was swimming close to me in purpose. Anna was sleeping on the shore and Robert was getting more curious and brave.. I started spitting out the cum from my mouth which fell onto Joe's cock and balls.Joe angrily said, "Whores do not spit out cum they have earned. You're going to clean up all the cum you've spit out and swallow it like the good cum bucket slut you are."He grabbed my head and forcefully placed my face back down on his cock. I was so scared at this point and did what Joe demanded. I used my tongue as a spoon to scoop up his salty cum from his cock and balls back into my mouth. I swallowed before. In no time at all my friend was sat at the end of the bed taking photos of my gf fingering herself and she was loving it.My mate must have had some amazing photos and after a few minutes of enjoying her photo shoot she opened her eyes again and said she wanted to see us wank for her. Wanking with my best friend isn’t something I’d normally consider but this was so hot that I don’t think either of us gave it a second thought. I was kneeling by her head stroking my aching erection and my mate was. . I closed my eyes and drifted, my mind and body separating as before, the oh so familiar sense of watching myself, my mind focused on the detail, intent on my subject, unaware of my hunger, my thirst, the loss of feeling in my leg folded beneath me as I sketched.I don't know how I did it, maybe I didn't? Maybe the pain was just to much and it overloaded my senses? All I remember is feeling detached, watching the girl releasing me, her voice broken by her sobs as she pulled my arm over her.
