I'm 19 years old and and since May finally have a serious girlfriend. But soon after I told my mother who 39, her behavior change. She started to only wear a robe at night and would "accidentally" flash me. She also started to always be hugging me and kissing me. The in June she started to come into the bath room where I was showering. She said she had to use the bathroom, take off her robe and only get up when I was getting out of the shower and could see her naked. Then one night in June, I woke up to find mom naked and sucking my cock. I tried to push her off, but she held on to me and kept sucking. I just gave up and let her. But soon I was enjoying it and as I got close I held mom's head as she sucked. Finally, as I came I said "Don't stop, swallow my cum, please!" I couldn't help it her mouth felt so good. I came and mom swallowed. We layed there, afterwards and fell asleep holding each other. Since that night, we have sucked, fucked, gone 69 and anal when we are alone. It is the best sex I have ever had. I'm seeing my girlfriend less and less once or twice a week, and the sex is no were as good as it is with mom. I'm have trouble even getting hard with her. I find I only want my mother's pussy. Mom is a wild animal in bed and only wants bareback raw sex. Also mom always swallows my cum, my girlfriend will not. We have done it every where in the house, our yard in the pool. We fucked in the last row of the movies several times. I know it's wrong, but I don't think another woman could match mom sexually or in turning me on. We have sex at least 2 times a day and 69 organism constantly. We are falling in love and want to get married.
