Yesterday I had to stop by to pick up my 12 year old son from his grandma's house and walked in her house and he was nowhere to be found. My MIL came out of her bedroom wearing a big t-shirt with no bra exposing her big nipples and I wasn't sure if she was wearing any shorts. She told me that my wife just picked him up. I was kinda livid for my wife not informing me, My MIL said to relax everything would be fine. She gave me a hug rubbing her nipples on my chest unintentionally, i then wrapped my arms around her squeezing her firmly and was aroused, she then tried to pull away but I held her for a few more seconds. She asked what that was all about. I told her that her breast felt great, mind you she is a 38 D size i know because I have seen her bras in her bathroom before. I bluntly admitted to actually wanting to see or feel her breasts before. She was in shock. I then told her to relax that everything would be ok. I was on my way out, but before I asked for one more HUG! She smiled and said OK. I held her nice and firm started rubbing my chest against hers. She told me ok ok ok that's enough. I let go and cupped her tit .She looked and asked me well what do you think was it everything you imagined. I was so nervous my hands were shaking. I pulled her shirt up and said Just a peek and that's it. I saw the nice big twins, for her being 61 years old her breasts still had some firmness to them but the nipples are like jumbo raisins. I rolled it with my fingers until I felt them get really hard. I asked her if she was turned on, She said yes but we need to stop. I said ok but after i suck on one. I brought the big twins together and sucked on her nipples for a few seconds then I let go of one and unzipped my pants and took my dick out. I grabbed her hand and put it on my rock hard cock. She held it with no motion until I bit her nipple she started to stroke me. I worked my hands to her crotch and she was wearing only panties. I felt her bushy hairy muff from outside of her panties. I slipped my fingers to the side of er panties and felt her Big wet lips and her clit was so swollen. Without looking at her i got down on my knees and stuck my tongue through the side of her panties and found her mound and put all of her pussy lips in my mouth. I felt her hands on top of my head moaning and wiggling, we found the couch somehow and I pulled her panties off and ate her hairy pussy good she came and was really loud her juices were in my mouth I had pubes in my mouth as well i could feel them in my throat still. I pulled my pants down and slowly put my dick in her knowing she probably hasn't had sex in years since the FIL passed away. I worked it and her words were "YOUR DICK FEELS SOOO GOOOD!" I asked her if she wanted me to stop at this time. She said " You need to finish what you started" While I was fucking her my cell phone rang. In the middle of fucking my dick deep in my MIL I answered it and it was my wife. She told me she had our son. I asked where she was. She said she was just getting home. I knew i had more time with the MIL. I told my wife I would be working a little late and I will be home in a few hours. My MIL looked me in the eye and asked What are we doing. I gave a hard thrust and she groaned, I told her I'm fucking you the way yo never been fucked. I sat on the couch and she sat on my wet soaking dick the wet noises her pussy was making was so hot. She smothered me with her BIG tits. I sucked on them so hard I left hickies by her nipples we even started to french kiss like teenagers she shoved her tongue down my throat. She was riding and grinding and I felt her inside squeeze as she was moaning and groaning really loud and her juices were all over my stomach she said she was cumming then I felt myself cumming as well. She came and I shot my load deep in her hairy pussy. It was a stress reliever i told her. She said next time your mad come talk to momma. I said ok. She wants me to fuck her at least once a week. I said if we can sneak it in. I will do more than just once a week. We cleaned ourselves up and I gave her a hug and piched her nipples while I slipped my tongue in her mouth and grabbed her ass. I said Thank you and til next time. She said goodnight and becareful. I got a text this morning her telling me she is sore but it feels good. I LOVE MY MIL!
