My step-daughter is 18 now and I ended up letting her jerk me off and it was so fucking hot. Then a couple days later, she came and got in the shower with me like a sweet little sudsy angel. I know! I need to stop. But her young tight body, pretty face and youthful giggle make me want to take it to the next level. I don't know how strong I can be. She asked if she could get it. I figured I would just help her get clean. But all I wanted to do was be very dirty. I rubbed soap on her perky breasts and nipples. Her perfect ass looks like her moms did 15 years ago, but better. Sliding my fingers into her tight wet slit cleaning it like a good daddy does. Washing her ass, going deep between her cheeks makes me so hard I could explode then and there. Teasing me and jerking my cock off with her ass cheeks. Hotdogging me between her ass crack. Grinding on me, all but begging me to fuck her. I had to kick her out before I went too far and slide deep inside her stretching her tiny young pussy. I don't know how much longer I can hold out
