I knew she was interested in me and I was somewhat attracted to her fully fit mature female form that made me visualize her bending over for my deprav...d exploration of her beautiful tight brown eye. I had determined that she was one of those special women that enjoy a bit of anal give and take without any pretense of a code of ethics that precluded experimentation with her ass up high.The nurse was there in front of the waiting room and she looked me over with that look that told me she was. With her fist in me up past her wrist she then started to twist it back and forth. First the pain was bad then it got so good and made me cum all over her hand. She kept fisting me liking that i was cumming faster and faster. "I knew you was a fuck slut. And you are a lesbian too." she told me.My step mom then decided to invade my hot ass. She took her other hand and began to finger my ass. With her fist twisting and turning in my cunt she rammed two fingers up my asshole. She worked three. "Sorry, lady, we can't help you," the first service station attendant said. "We are only a self-service station."The second refused to help, explaining he closed in five minutes and didn't have an assistant to leave at the station while he drove to find her.Looking at her last quarter, Melinda ran her finger over the service stations listed in the yellow pages. None of them seemed to offer a promise of aid. It wasn't worth the risk of wasting her last quarter. She bit her lower lip and decided. "I love your cock. Fuck me, please fuck me." It must have been the right thing because he started to pump me even harder. I knew from the voice that it was Steve, but I didn't care. I just wanted to cum hard enough to turn me inside out. I felt him begin to sweat and then his body began to slide on mine as he fucked away at me. I felt his cock drive in me then he changed to a side to side motion as well as the in and out. I was trying to grind at my pussy with his cock. It was maddening to feel.
