Caved In To Mother-In-Law Wishes

I remarried. My second wife was a bit heavier than my first wife with smaller tits but she was much younger and I was attracted to her because of her age . The fact she was years younger and she let me do oral on her hairy snatch which my first wife wouldn't do, led me to marry her. We went to her mother's often . I began eyeing her mother. Her mother was aged but had big tits on her. She reminded me of the fun I had with my first wife tits. I had good connection with my mother-in-law.
She stopped by our house while I was napping on the couch. I felt a hand on my semi hard dick. I thought it was my wife being frisky. When I opened my eyes I was surprised to see my mother-in-law standing there. " I need to ask a favor that you might help me with. " She began telling me her husband takes medicine that causes him not to have an erection. Her daughter confessed to her that I'm frisky in bed. My wife's mom confessed to me that at times she desires sexual relief and figures me being youthful can help her.
She exposed those big tits that she has and started massaging my privates. She's an older mature woman with nice looking tits as she slipped her hand into my pants and began tugging my dick. I began sucking on her big tit nipple. " Suck it hun ! Please this old gal ! " She unbuttoned my pants and pulled it off. To my surprise that old gal began giving me a blow job which I never expected from an older lady. She removed her bottoms and got onto the couch naked playing with her clit as I looked on. She opened her legs and begged me to stick it in her while she was still playing with her clit. I grabbed my dick and slowly eased it into her hairy snatch. I never had a snatch that felt so good. I put my dick all the way in her slapping her with my balls. " Please don't stop babe! " she screamed out. I finally exploded giving her the sperm I had as it leaked out on to the couch.
She cleaned the mess I made before her daughter finds it when she comes home. To my surprise my mother-in-law gave me a mouth to mouth heavy kiss and a " Thank-you ! " I said, " No, thank-you ! " as I groped her big breasts.
