Oh, how I had missed cock!I kissed Derek goodbye and he slipped out the window just as my phone beeped. Oh shit, Renette! The text read, "where r u sl...ave? my puss needs attention".Fucking bitch! I threw on my robe and was just opening the door to leave when I spied the two used condoms on the bed. Hmm...I thought. I dropped one into my robe pocket as I went.Renette was again lying there waiting with her legs splayed, ready for me. I suggested that she turn over and I would use one of her. I don’t know where the idea came from at that particular moment but Adriana’s hand that was clenching Mum’s ass came free as Adriana slapped my mother’s ass.This time Mum groaned her approval and pushed her ass outwards indicating her partner was free to spank her again if she so desired. Watching this little interplay gave me ideas for future contemplation.I was also surprised at this entire turn of events. I had only anticipated Mum stripping the two women down for my viewing pleasure. It. When we saw the red strip we either stayed out until the "partner" left, or we sneaked in quietly and watched the action from behind a one way mirror we've installed in the bedroom.Two weeks ago, I came home at about 5:00pm and saw the red strip on the curtain. Tina knew when I was due home so I was certain that whatever she was doing was close to the end, so I sat waiting in my car. True to form, about 10 minutes after arriving I saw the front door open, and to my surprise - a young boy came. It felt so-oo good. And his massaging was making my cock fuck into the silk under my belly!He asked me how it felt. I just grunted. He said I’ll do your bum as well, stop it being numb. His fingers were expert at their work. I was trying hard not to moan and hump the soft silkiness under my cock. It wasn’t long before his massaging became a little more intimate.He slipped a finger into my hole, oiling it in and out. In went another. He said do you want some more? I just nodded. I think I’d lost.
