I couldn't wait for the next day to arrive and being a sales guy I dressed in my work suit and left home as usual for my day's work. I work all morning and arrived at my Sister-in-laws house around 12 as planned. She answered the door dressed only in her dressing gown and a towel round her head as she had just got out of the shower she said. Come into the kitchen and I'll get you a coffee. Once in the kitchen I was like a dog on heat all I wanted was Dennise so I caught her arm and turned her to face and pulled the ribbon holding the dressing gown closed. The dressing gown now opened fully and my eyes feasted on this very sexy woman who was totally naked. Her large breast hung like melons and her fanny was clean shaven. Slow down she said in a teasing sort of way and then she let it slip to the floor moved in closer and kissed me hard on the mouth then she kissed my K neck and bit my ears oh my good she was sending me wild and all the time we kissed I was squeezing her nipples and tits. Denise the said stuff the coffee and led me into the bedroom. I stripped in a heart beat and my 7" cock was well on display so Dennise dropped to her knees and started to suck it just like the night before but this time she was spitting on it and saying "I want your cock now!! She then moved into a doggy position and backed onto my cock shouting fuck me oh god please fuck me which I did as hard as I could I was pulling her hair holding her head back and she shrilled with every thrust until she shouted I'm coming oh fuck I'm coming I couldn't hold back any longer and also came deep inside her. We both collapsed on the bed and held each other for about 10mins then I gently stroked her tits and played with her fanny while she stroked my cock back to life. I fucked Denise several more times that day and even screwed her arse. I never saw her as plain or shy ever again. Wonder why?
