Did I Miss Something ?

I’m am married man with a woman with great sex life with 3 kids , Recently I had to go pick up some tools from my uncles house that I needed to use for fixing a car I was working on. In his house lives him and his wife and my grandmother, mind you my grandma is in her 70s short Latin blond but has health issues some days she’s great some days she’s off and her balance is off as well . when my uncle and his wife go to work my grandma stays home by her self most days. This was one of those days where she was alone and not feeling well so I called her to see if she needed something since I was heading there anyway but she declined and said “ no iam fine honey but I’ll unlock the door and ima go lay back down “ I said ok grandma when I get there I’ll go check up on you to make sure your ok. She said ok thank you . I get there and sure enough door is unlocked and I grabbed the tools I needed and put them in the car went back inside to go check up on grandma. Her door was cracked and lightly tapped and she said come in , there she was laying in a towel ! My heart and stomach dropped I was shocked since I’ve never seen my grandma in such little clothing and all the dam grandma porns I’ve seen not only that but a confession as well when I was young probably about 10 years old I had a little curiousness and would sniff her panties and they always smelled so good. I walk in and she’s says please excuse me I was going to shower but wasn’t feeling well so I laid back down I replied with no problem at all is there anything I can help you with maybe getting up something ? And she was like no ima wait a little and started a conversation with me and slid in the middle of conversation saying she hasn’t been with a man for 20 years and i interrupted saying what!!? I cant go 2 days with out wanting action and I asked her how does she do it and she’s like after a while you kinda just live with it. As she talking she’s slowly moving her head off her pillow and moves it closer to the edge of the bed making her look a bit uncomfortable but almost like she wanted to be there . I noticed how level my dick was to her head giving me a natural feeling of whipping my dick out and just laying it across her face. That’s how close she was to my Jeans . I was quick to mention something off topic thinking my perverted ass was having terrible thoughts of my innocent grandma but she brought it back up about her past and at this point I convinced my self she was signaling something as she stands up her towel comes undone showing her amazing saggy tits with small quarter nipples . I was rock hard in the moment . As she’s standing she points at the wall to show me some baby pictures she has on her wall, as she’s pointing with herbback is against me causing my hard dick rubbed on her ass 2 times I knew I had to go but at the same time I was oddly having a bit of fun too. She asked if I could stay while she showered and I agreed. I waited in the living room since my uncle has indoor cameras and didn’t want it to look wierd me being I her room for such long times . When she came out she was soaking wet in her towel and went heading to her room im thinking ok she’s probably going to get dressed , shortly after I hear come here ! So I walked in and she’s still in her towel dripping wet walking around in her room showing me things almost like she wanted me to make a move ? I never did anything but hasn’t left my head since .idk if I should text her saying something about it or say something like were you signaling something to me the other day ? Idk what do y’all think and yes this is real .. I know I married but also would love to help her if I can . She deserves some attention too
