Her hand was making it's way down to his crotch, right where the over stuffed bulge in his pants were. Hen she felt the huge hard cock thru his pants ...he exhaled and almost tore his pants off. I heard the whole story about how when she put the tip of the head of his cock into her mouth that she actually came just by the presence of his huge beautiful cock. I also heard her as she said that she swallowed so much cum that she even used it in her hair.I helped dad into his place and both Kristy. I arrived home one evening after being away for 2 weeks. We went out to dinner and I told her I picked up something like goat weed pills for a wild night in bed. The pill for me was really a male stamina goat weed pill but the pill for her had a little something xtra to make her really horny lol. After having several drinks & taking our pills we arrived home. The pills & drinks were doing there job so I said Ill be in the room in just a few as she went in to take off her cloths. I called up my. Mainly due to that I hardly saw her as at work, she was mostly with John and when home she was in her room. The only time I did see her was when the three of us went for dinner.However, she was always hugging me and telling me she loved me but sometimes I wouldn’t return that love. John brought me over a whiskey telling me here this will calm your nerves. I kicked it back but it really didn't help much. John went to the kitchen got into the car key cabinet and returned handing me the keys to. .. it was an honest mistake she said I don’t think my sister will like that to much. We laughed never told her. So she was watching me made sure I took my meds and started the shower for me. I got undressed showered, then when I tried to get out my bad leg tripped me up. I fell... Hard. I hit my head and the next thing I knew my SIL was rolling me over then trying to put her arms under my armpits and pick me up. Naked My face buried in her tits. By the way she was wearing yoga pants, and a skin.
