As the head rubbed the roof of my mouth my tongue continued to lick the underside. I began to find a rhythm, slowly bobbing in and out, licking and su...king as his penis slid out, using my tongue to hold it against the roof of my mouth as it slid in. I became more and more comfortable with taking it deeper and deeper until my lips found the base of his cock. It wasn't especially long so I forgot my worries about gagging and increased my tempo. He let me do all the work as I held onto his ass and. He let out a long sigh. I kept my lips tight and pushed forward, again, jerking him off with my mouth as I continued this back and forth motion. Finally, I released my lips, briefly enough, to take a full breath of air. On my forward plunge, when his cock was up against the opening to my throat, I tilted my head and pushed forward more, taking him into my throat. His hands began to grip my head. I let him hold me in for several seconds before I pushed back so I could get some air. Then, I. Rachael looked up at him andnoticed his eyes were going back into his head like he was having somekind of seizure of something. She looked away but that's when shenoticed his large erect nipples. Strange how they looked much like thefemale nipples she liked to suck on. As she kept the rhythm of strokingDerek's cock she reached out with her tongue and flicked his nipple.

Then came the call that was going to change my life forever.I had been so depressed and so lost that my sister, worried for my sanity had actually called Cecilia and told her all about it. I was fed up with all the crap from Linda and her 25 year old dead beat son that suddenly she moved in with us. I wasn't quite sure how to get rid of them without making a huge mess.Any way, the call came to me at work. "Dad, I have a terrific idea." It was my sweet.
