My wife and I have been on vacation with my wifes parents for the last few days and so far it's been nice just to have some extra help with the kids. We haven't had much time to ourselves since the twins were born and you can probably imagine how taxing the kids can be on my wife, and on our quality time together. We have an amazing relationship and work well together but when it comes down to it, we're always just so busy. This vacation was necessary and has been rejuvenating for both of us so far, allowing us to at least forget about stresses like homeownership, cooking, cleaning and laundry since my mother in law is a saint.
My wife is a busty brunette with an athletic build and her mom is an even bustier brunette who's never played sports but always has her hair and nails done and only wears heels. They're both very attractive and my wife knows that I have a thing for her mom, especially since I have a thing for big tits. My wife and I have a very open and honest relationship and I've held back no comments over the years, which has admittedly worked out better sometimes than others, but still seem worth it overall. I believe yesterday is definitive proof as I've never came so hard in my life.
My wifes family is big on alcohol and all day yesterday my mother in law was making us the strongest drinks either of us have had in months. My wife and I were able to relax all day by the pool while my wifes parents handled the kids and joined us in between the kids naps. This was the first time my wife had put on a bikini since having the twins and she's recovered remarkably, filling out the bikini better than ever with her engorged tits, skinny waist, and wide hips.
Seeing her mom in a bathing suit was also a rare treat for me as she doesn't usually join us unless it's really hot out and she needs to cool off. My wifes mom was wearing sunglasses and a very low cut cheetah print one piece that pushed her deep cleavage up to her chin when she got in the pool with us. I could barely contain my excitment and my wife noticed instantly, giving me looks every time her mom looked away.
Slowly my wife went from giving me looks to subtley teasing me throughout the day. Every time my wife was floating behind her mom my wife would push her tits together to try and imitate her moms bust. Seeing the two of them in front of each other with my wife daring me to compare her and her moms tits got me hard and kept me hard for the entire time in the pool. I should probably add here that I'm a pretty big guy with a pretty big cock and a healthy sex drive.
Besides having a milf kink, and I suppose now a gilf kink, my wife knows I also have a bit of an exhibitionist kink. Knowing how much she was already teasing me, my wife was ready to push things to another level. My wife chugged her drink and asked me to get out and get her another, knowing how visible my cock would be for anyone who was looking in my direction. I did my best to adjust and hide my cock and distract my mother in law, even though I secretly wanted her to know how hung I really am.
