Sally was apprehensive and thought it would be dirty. I said she could douche herself and then she would be clean. Well, one thing led to another and...before I knew it I was fucking her anally all the time. She loved it. In fact it became a regular part of our lovemaking. She would come two of three times while I fucked her in the ass. We did all positions, but she liked it best when I fucked her from behind while she lay on her stomach. She had a great ass and I got very turned on and would. I tucked my cock back into my jeans as I parked my car. I sat there for a minute, nervous and excited. For a brief second I thought about just heading home and not going through with it, but my cell rang, it was Bill calling to see how much longer. As we spoke on the phone, my cock began twitching in my jeans. I was less than 25 yards away from a fulfilling my fantasy of having sex with another man. I told him that I was parking, and I’d ring his bell in a minute or two.I was expecting. In one final attempt, I whimpered out"Please..." he bent over me and got really close to my hear while his fingers gently started moving in and out. and he whispered in my ear,,"Shh... shush. It's ok baby. I’ll go really slow. I’ll make it good for you. And by the end, you'll be begging for me to take you again and again. you'll be my own personal slut, free for me to use as I please. would you like that baby? would you like to be my little slut?" and before I knew what I was saying, the words. I then went to my bedroom and fell asleep with the scent of her pussy still in my nose.Later that night I awoke to hear my mother come home. She walked quietly down the hall, and then opened the door to my bedroom. Still feeling a little guilty, I lay dead still and pretended to be asleep. After a few seconds, she drew the door shut, and went to bed. She never did mention the missing panties, much to my relief.A few weeks later, my mother decided to go for another night on the town. This time.
