I was married when I was 30 and my mother-in-law loved me. She had four daughters but always wanted a son and I was going to be her first even though I was actually going to be her son-in-law. A couple of her daughters got married in the years that followed so I wasn't her only son anymore but I was always her favorite and had a really close relationship with her.

One weekend I was going to spend a few days at her place alone to help with things around her house and we began talking. She was no longer married and told me she had always wanted a son. She tells me she had always wanted to give her son a bath. She added that it probably sounded stupid but it was something she always wanted. I told her it didn't sound stupid and if she wanted she could give me a bath. She told me I was sweet and suggest we do it now. I didn't expect her to take me up on it but she actually was. She told me to hold one while she went to go run the bath water. She comes back and tells me we need to get her little son ready for his bath. She starts to take my clothes off and I realize she is going to see me naked for the first time. There I was naked being let into the bathroom and into the tub. She begins to lather me up and that's when I realize she would have her hands all over my body. I figured she would use some restraint in where she touched but no area was off limits. She was talking to me like I was an actual little boy and tells me we need to clean the smelly parts really good. She was washing my ass and rubbing her hands between my legs and in my ass crack. She even had a finger go partially into my asshole. It became awkward with her washing my balls and my cock. She was gripping them and getting me very aroused and caused me to cum. All she said was that her boy had a little accident in the tub but that was OK. I couldn't believe she did that but it did feel good and figured you can't change what just happened. She finished bathing me and then decided she was going to do a little more with me. She put a sheet on the floor and had lay naked on it. Out comes a bottle of baby powder. She is holding my legs up and putting it all over my ass and genitals. She then grabbed a towel and pretended it was a diaper and put it on me. She said it looked like I was hungry and she was going to feed me. She takes her dress off, followed by her bra and pushes one of her nipples into my mouth. I begin sucking on it and realized she is really enjoying what we are doing. Finally she says I needed another bath to get all the baby powder off me so we were going to have another bath. She lead s me to the tub in the diaper before she takes it off and has me go into the tub. At this point she is in just panties and her nylons but soon takes off her panties. I am sitting in the tub when she puts her foot up on the edge of the tub and slips each nylon off in a very sexy way. With her foot up I got a very good view of her pussy. She then climbs into the tub with me and tells me it will be easier to wash her boy this way and I could wash her too. The washing lasted less than 5 minutes before I was hard and she slipped her little boy into her.

This evening was unexpected but it was fun and she was a good fuck. We had done a few other things and now she loves spanking me and I love getting spanked.
