As efficiently as he could, he scooped thingstogether and covered them with whatever he could find before he stoodback up again. He had no doubt his ...face was very red as he took thetwo bags she had been holding and said, "Thank you." Then to finallyget her out of the way, he added, "Now, if you'll please excuse me, Ihave a lot of work to do." Oh, of course," she said, still somewhat surprised. "Oh, by the way,my name's Melissa... Mel." She stuck her hand out to shake his, but hishands were. Mark was wanking like mad and started to groan saying he was Cumming, I carried on wanking but watching Mark, I could not believe how big his cock was, all of a sudden he groaned and a thick cream shot from his cock and onto the floor his cock pumped cum out like a open tap, Mark squeezed his balls making sure the full load got out, he lay back on the bed his limp dick hung down, I kept watching the DVD and wanked like hell I was close and it felt like a huge load, my balls started to get tight. Sarah went up to him, took his hand and led him to the bed. She kissed him softly on the cheek and he sat down a little stunned and perplexed. His brain was wondering what the hell was going on.Matthew could see that Sarah was back to her normal self and he relaxed a little, but in the back of his mind he felt a little scared about losing the relationship he was having with his sister. He was relieved when Sarah went on to explain her actions.“Sorry Matthew, I couldn’t help it, I didn’t mean. I didn't care. I unbuckled my belt and opened my zipper and displayed my panties to my mommy."Good girl!"She swatted me in the dick and kissed me on the cheek. And off she went. I felt blessed to have her in my life.Last week she called me up out of the blue. It was a Thursday night and I had to work the next day. It was about 9 pm. She was giggling on the phone and sounded like she had had a few drinks. I could hear other people laughing in the background."Markie can you come over and visit.
