My wife’s sisters and mom

So my wife (30) and I (32) have a very vanilla sex life and my wife’s sister (27) just moved in with us about a month ago till she gets back on her feet. Her mom (59) has also been around a lot lately helping out and what not. Her sister has been wearing these tiny shorts with her ass hanging out and my wife doesn’t say anything about it. Her mom came over the other day and wasn’t wearing a bra and when we were all hanging out her mom was saying how she hasn’t had sex in like 5 years and my wife’s sister said get a toy and she said nooo I want the real thing. I was starting to get a lil hard talking about all this sexual stuff and I’m about 8 inches hard so I adjusted myself I was wearing sweat pants and her mom looked straight down and smiled at me. Later when she left she gave me such a tight hug I know she could feel my cock against her leg. She later txted me that night and said it was so good hanging out with us she wants to make it more regular I said of course with a smiley face. Later that night my wife’s sister txted me and said my mom really needs to get laid and so do I.. I go well you weren’t in your last relationship and she said I wasn’t getting fucked good at all. I honestly think both my wife’s mom and sister wanna fuck me bad. I’ve been a little flirty thu txt and there doing the same thing back.
