I was glad I’d called in reinforcements.I awoke with my cock down someone’s throat. The sudden stimulation blended in with a dream I was having th...at involved a lot of sex, so I thrust upward, driving my hardening shaft into someone’s mouth and making them gag slightly. I heard a “Mmffftt” sound.The female pulled off of me, “Good morning, Sunshine.” Rosalin’s naked body was lying between my legs as she fellated me.I looked around and Pam and Trish were not in the bed. I asked, “Where’d the. We fucked like this for perhaps 5 minutes at the most, the incredible heat from the situation was unbearable and I couldn't hold on any more. Right as I was about to explode in my sister's twat I realised I had no idea if she was using any birth control. I released her ass and pulled my cock out of her right as I began to erupt molten semen. The first blast splattered squarely against my sisters pussy and ass hole as I struggled to aim over her back. The proceeding blasts coated her left ass. Pictures of my wife, kissing a man. Pictures of my wife dancing with the same man in a bar, while his hands groped her ass. Pictures of my wife tilting her face up toward the man and smiling that smile I thought I was the only one to see. And lastly, pictures of my wife and the man heading into the Seaside Motel out on Benton Road. The timestamp in the photos said these were from last week. I had no idea who the hell the man was.After I returned from spewing my breakfast I stuffed the pictures. Feeling it happen with both of them at once was special ... and faintly alarming.The other girls visited me at night as well, usually in the company of their twins. There was even one night that Lisa and Lori slept with me. It goes without saying that sleep was all that went on that night. Well, that and some snuggling and cuddling. It was all very innocent. Lori had experienced her kiss from me and that seemed to be all she needed ... for now. The 'for now' part worried me. Lisa didn't try to.
