my sis in law is a flirty sexy woman. 31, married, 3 kids. Shes 5*8, blonde,green eyes, big pert tits, nice ass .I hav e fancied her ever since i started going out wit her youngest sister(whom i married).
My wanking fascination with her started on a beach when i saw her getting changed standing by her parents car, she was 21, and changing into her swimsuit while standing beside the car, there was plenty of their relations about, and i stole a peek at her big tits as she put them into her bikini top, and saw her pull up the bottoms over her ass.
Later that day she was lieing down in front of me, i was sitting on a chair, she pulled out her bikini bottom and i saw her pussy! she was pulling it out to make it fit comfortably, my god ...an instant rush to my cock!! i wanked for years remembering that sight.
Years later her sister and i married , and we were staying in their parents house while ours was being built. The sexy sister was there regurlarly and we stayed in a bed room upstairs, so 1 day my wife was out, i was upstairs, havin a wank, when her sister called to see her mother who was downstairs.I thought this could be a chance, so i opened the door back about 3 quarters, and continued wanking.
Soon enough i heard the sister say to her mother that she had to go upstairs to get something or other, YES! so i half turned to the door, and was wanking away on my throbing hard cock.She walked upstairs, and was walking passed my room and she stopped for 2-3 seconds and looked at me (i was pretending not to see her,and was looking out the corner of my eye) she watched but then kept goin..... i shot my load of spunk all over... She never mentioned it..
i have gotten the chance to hold/feel her when having a dance at family parties/weddings etc, but 90% of all my wanks are about her....
