Mother knows best

I think of myself as a normal mom, I'm 46, average looks and body, and have been married twice and I'm divorced as I type this. I have a daughter attending college in another state. My son is attending a local college and lives at home. I've known my son masturbates for quite some time now. I caught him a few years back, but told him it was normal and healthly to do. Now we didn't quite have an open door policy here at home. At times though my son would leave his door ajar and I'd see him jacking off. I'd just make a funny comment like, take it easy, Craig. Now I know he's my son but It was a bit of a turn on, so in private I'd go in my room and masturbate myself to the thought that he was jacking in the next room. One night this past summer we were watching TV, some movie on cable that had a few nude scenes. Craig was just wearing a pair of gray cotten shorts. Anyway I noticed he was rubbing his penis thru his shorts. My first thought was to tell him to go to his room if he wanted to do that. Before I could say anything though, he saw me a said he was sorry. He told he had forgotten I was there. I told him it was okay, and for some reason told him it was okay if he wanted to do it, I reminded him I had seen him naked and jacking before. Craig was sitting on the couch and I could see he was still hard. He was rubbing it again still with his shorts on. I told him he should atleast be comfortable, so he took his shorts off. He asked if I was sure it was okay. I said sure, And if he wanted I might join him. Judging from the way his penis jumped when I said that, I proceeded to remove my panties and night shirt. Looking back I'm not sure what I was thinking, I don't believe I was thinking of him as my son. I sat next to him on the couch and laid back and started rubbing my clit. I couldn't take my eyes off Craig's penis as he stroked it slowly. its 6 inches and shaved bald. I couldn't believe we were doing this, It was sureal. Craig asked if he could touch my pussy, and in the moments heat I let him. I flinched at his touch, he was rubbing my clit with his thumb while he fingered me. I had reached over at this point and was running my hand up and down his penis. his breathing was heavy so I knew he was enjoying the hand job. His fingers were working magic on my vagina aswell. I don't know how long we were at it, but I finally felt Craig tense up and a jet of semen came rushing out. At seeing that I had made him come I started tensing up and moaned in pleasure as I came. After we snuggled for a bit and just sat and talked. I felt in some weird way we were closer, not just in a sexual way..... more of a bonding. Since this summer we've had several more masturbation sessions. I do know this is just a faze were going thru, but I feel in some way it is making us more open and hopfully Craig will always comfortable talking to me about anything. Masturbation can have some positive results. And not that I would ever recommend parents to do this, It deppends on the situation.
