I came home from a friends house one evening and I had a problem. See I took this pill thinking it was to help with my back. Needless to say shortly after I took it my dick got hard and stayed hard. When I got home I went to my stepmoms room to find out what was wrong. I told her that I took a small blue pill and shortly after my dick had been hard for about 45 minutes. She laughed and said what I had taken was a viagra. This had me concerned because I had never taken that before. She crawled to the end of the bed and said she needed to take a closer look. Then wrapping her lips around my throbbing dick she sucked and stroked telling me this would help. I was so turned on as she was swallowing my dick. But it wasn’t working, my dick was still extremely hard. So I stood her up and bent her over and fucked her hard from behind hoping that would help. But it only made my dick harder. It seemed like nothing was working. Meanwhile my stepmom had cum while I fucked her from behind. She had me sit on the bench and she lowered her tight pussy down on my shaft and she started bouncing her big plump ass up and down my dick. I have to say her ass looks so fucking good when it’s bouncing like that. But again it wasn’t working so I laid her on the edge of the bed and had her hold her legs open wide while I thrusted hard and deep. She came again on my dick when I put my hand on her throat. By this time I didn’t think anything was going to work to make my erection go away. That was until she had me lay on the bed and she backed her ass up and sat right down on my dick and rode me reverse cowgirl. Pushing back harder and faster. Something about that big ass and tight little asshole did it and I came hard and deep inside her little pussy. I’m so glad my stepmom could help because I don’t know what I would have done if she wasn’t home.
