Once he got really lucky when instead of getting ready for bed, she lay back down on the bed and began playing with her tits and nipples! Just watching her twist and tweak them made him cum after only a stroke or two, and even though he had just shot a load, he continued to watch and was soon rewarded as she dropped a hand to her crotch and frigged her clit! Mark had never seen anyone do that before and was fascinated that girls as well as boys "did it"! When Sarah finally came, she stifled a scream and writhed her body all around the bed, unitl totally spent, she lay there for a few minutes mindlessly massaging her mound and tits. What a sight!!! Sarah's cunt was gaping open and was red from the abuse she had just given it.
Mark saw her masturbate many times after that, later on catching her using a thick candle as a penis substitute and fucking herself hard and deep with the big wax "cock"! It was when she used the candle that Mark thought she came the hardest orgasms! Mark started going through the dirty laundry, and after removing Sarah's dirty panties,he would watch her masturbate, with a pair wrapped around his swollen dick while holding another pair up to his nose so he could smell her pussy as he watched her cum! Using her panties became a ritual, and he had huge cums when he had a pair under his nose and one around his meat. On nights when his sister had sleep overs he got to see a variety of her friends, and although not always naked, it was still fun to blow a load watching a bunch of near naked high school girls jumping and playing around! One of Sarah's friends was a little blond with big tits named Karen, and although he loved her tits, what was really neat was that she wore very tight panties that outlined her bulging pussy, and while he never saw her nude, he still loved to cum watching her sit cross legged on the bed with her panties pulled tight revealing a nice crack in big labia!
