I Want My Mother In Law In The Worst Way

My mother in law is only 11 years older than me. I have always had a thing for attractive older women. I love my wife very much and she turns me on really easy. I am thankful to have her because I am lucky to even have her at all. That is why the lust I have for her mom is horrible! Her mom got a tummy tuck and boob job after her last baby. With everything she has going for her, it gives her body the perfect body type that turns me on. Everyone has body types that turn them on, but every man has a very specific preference. Her mom has that preference. I think my wife is more beautiful in the face, but her moms body is my desire.

The thing is though, I think her mom is aware that I find her attractive. She has no problem wearing tight yoga pants around me, with no bra that makes her nipples show. She dances and does things in front of me and grins in my direction, as if to see my reaction. My wife unknowingly enables it too. Heck maybe it is knowingly enables, I don't know. Regardless, she encourages me to look at her moms butt, dances with her, and makes comments like "you know my mom is hot" in a joking manner. I mean they both know her mom is attractive for her age. She could seriously start an Only Fans where she doesn't even have to get naked, and she would make millions. She is trying to convince her mom to move in with us and then we all buy a house to "live happily ever after" (her words). I am ok with that, but nervous about it. Frankly I don't want to be put into a situation where I have to decide if something is a trap, or to have choices that can lead to down the road consequences.

The short of the matter is, I don't think my wife understands how much I find her mother attractive. The thought of merely seeing her mom naked turns me on like no other. Let alone the prospect of burying my face in her pussy and her ass. Lately I have had this fantasy of her mom moving in with us. Then after some time has passed, me, my wife, and her mom will be sitting on our bed just talking (we have done this before). However, the conversation turns to her mom feeling sexually deprived and she doesn't feel beautiful. I tell her she is beautiful and should never worry about that. My wife kisses me and calls me sweet. While we kiss, her mom suddenly unable to contain herself starts rubbing herself. My wife notices this, pulls my pants down and begins to suck. He mom pleasures herself next to us while we make love. After we cum together, my wife tells me to finish her mom off and she says yes please. I pull her pants down and eat her pussy. She cums quickly. After that my wife gives permission to me and her mom to do anything we want if she isn't around. Next time my wife is at work, her mom asks me to come to her room. She is on the bed in just bra and underwear. She asks if I could eat her out again. I obliged. Thinking we are done, she tells me to lay down. She takes out my dick and begins to suck. After a few moments she climbs on and rides me. Unable to take it, I ask if I can do it to her doggy style. She says absolutely and we shift positions. I am now staring at her beautiful ass and I ram my cock into her pussy from behind. I nut quickly, unable to take it. Later that night I fuck my wife the same way, to make sure she knows I still love her and find her attractive. My fantasy is that I could stay in this kind of relationship with the two of them for the rest of our days. Just having them both satisfied, but we all live a normal life together. She and her mom are close and have always shared everything. My wife has always wanted to please her mom and keep her happy. Why not share me as well?
