I Wasn't Quite Expecting That

I have been a very naughty mom for this last year. My son was over at my house and we were watching TV and in the show this woman was tied up. I laughed and said how that looked like fun. He teased me, and I admitted that sometimes things like that could be fun, although I said that I never had been tied up. He suggested that I get my boyfriend to try that with me. I told him that I really didn’t trust my boyfriend all that much to do something like that. My son then teased me some more and said how he would be glad to do it.
I thought about this, and a week later I surprised my son by having bought some soft thick red rope, and asked if he wanted to try tying me up. He grinned and asked if he could tie me naked to the bed. Recklessly I said, sure.
So we went into the bedroom and I bravely undressed and he proceeded to tie me naked to the bed. Well, he started playing with me, which I half expected him to do. He played with my breasts and sucked on my nipples and fingered me between the legs. He then took off his clothes and presented with me the very stiff erection that he had and he fucked me! In fact, he fucked me twice! I couldn’t believe that I had done this with my own son.
Well, it was a lot of fun and we repeated the experience. Then another time he tied me face down on the bed and had anal sex with me, which I had never experienced before. He loved doing that to me and I found it very exciting having my butt fucked like that. It was certainly a new thrill.
Since that time my son has repeatedly tied me up and has had sex with me in all sort of ways which I find so exciting. I have since stopped seeing my boyfriend and exclusively now enjoy having sex with my son. I wasn'y quite expecting that, and who would have ever thought!
