I'd had a crush on my sister in law for a while and when we were visiting her apartment once, she and my wife (her sister) went to the store in the morning. I woke up extremely horny and feeling devious so I walked into her bedroom to just see if anything caught my eye.

Her bag of sex toys was open and right next to her bed! It contained a vibrator; lube, and anal beads. I was rock hard and knew I didn't have much time, so I stripped and began smelling her toys. They had clearly been used somewhat recently.

I knew the anal beads were what I wanted to play with most so I laid back on her bed, inserted them with a gasp of pleasure and began stroking while smelling some dirty thong panties that were on her floor. As I became even closer to cumming with my sister in laws toy in my asshole, I turned on her vib and laid it against my shaft...fuck. They could have come back early and I would be so screwed...

Luckily I came hard - very hard - shortly after the vibrator was against me and I put things back where I found them, carefully.

About 10 minutes later they returned. No one knowing I'd had a very good time with my SIL's sex toys.
