sex with my sisters builder....

I was at my sisters place when the builder came to finish some work he had been doing for her, she was called away and asked me to make sure he has everthing he needs, with that came a gorgous smile on his face and my responce was sure thing sis.
She had only been gone 5min and he pushed passed me, rubbing up agaist me, I am a women who loves nice ass in jeans and a gorgous smile and I melt, well I'm sure he saw me melt and in one single movement grabed me and started passionatly kissing and caressing my breast, I was soooooo wet i couldn't help myself, I lead him to the bedroom I use when I stay, we fell onto the bed and continued on our merry way, it was so wild I couldn't beleive my luck, all of a sudden we heard my sister yelling out to me.......... 2 hrs had passed and we still had more were that came from, only he hadn't done any of the work he was there to do. She now askes me if I can look after the builder each time she gets work done,
as it was so gr8 for me I carn't let my sister down, and of course I do as he wants and help him with his tools :-) ........ Oh and my sister thinks it's gr8 as she never gets a bill.........
