I wondered if she would see my obvious hard on and be alert.I held up my hand and loudly told her to "Stop right there young lady." She looked up conf...used. She had been concentrating on her cycling so much she didn't even see me until I called out. She quickly pulled to a stop and looked up at me, already looking a little nervous. I have found that the secret is to be commanding and assertive as hell. Even the most innocent girl will start to wonder what she did wrong when I'm standing there. I couldn't believe what I was seeing - my Mum sucking my girlfriend's pussy and it made me so horny as my dick was once again large and hard as I sat back and watched. My right hand cupped round my dick and I began to masturbate slowly. Alexia and Mum's pussies rubbed up and down each other's as they fucked. Their clitoris' hot making them get even more excited as they fucked harder. I masturbated harder and as they orgasmed I did as well. Sperm spurting out all over my breasts and stomach. . I acted instinctively and took the head of his cock into my mouth. His cock was so big and thick. His flesh felt soft yet firm in my mouth. I sucked him in and out a few times, savoring the taste, then boldly reached up and held onto his hips. I could tell I was doing a good job because Ben was moaning and saying, "yeah, yes, yes." His pleasure encouraged me and I moved my hands to his ass and felt it and squeezed it. I took as much of his cock into my mouth as I could, but it wasn't much more. We pulled up to the cabin and made our way to the front door. We kissed passionately and you could feel the heat between our body and the passion in our souls as we stood there kiss each other. It was a kiss we both had been missing in our life for sometime. We finally broke our kiss and I was working on unlocking the door to the cabin. Before we could get into the cabin we kissed again and this time our hands worked over each others clothed bodies. Me grabbing her hair with one hand pulling.
