My sister in law is visiting with her family for a few weeks and conveniently left her husband at home. She’s older than my wife, but in better shape since her kids are older and she works out regularly. My wife is more curvy, but something about her sister is just overall sluttier. Like I always thought she’d be more fun in bed.
We were all at the pool yesterday and when we got home it was a flash of wet towels and bathing suits and kids changing in just about every room so I managed to slip into my bedroom to get changed in peace. I thought I locked the door, but sometimes it doesn’t fully engage, so while I’m just dropping my suit to my ankles and standing stark naked in the middle of the room, of course the door opens and in walks my sister in law Liz. Now the interesting part is, while at the pool, Liz was very flirty and looking very sexy in her bikini. Despite being fit and petite with little tits, she still has a pretty amazing ass. And she flaunted it in my face every chance she got, even rubbing it up against my crotch “accidentally” as we both stood in the pool. So while I was changing, naturally I was touching myself a little while thinking about her. I say all this because at the moment she walks in, I was definitely sporting a semi.
