Glad she's not a good house keeper
My wife's sister was going out of town for a few days and needed someone to take care of her cat. My wife had the job of doing it all but the one time I did.
When I arrived at the house, I let out the cat and filled the food and water dishes. I noticed she had a clothes hamper in her kitchen beside her laundry room. I decided to look for some panties and found one pair in the bottom of the hamper. My disapointment was high when they turned out to be a dust rag. Thinking that her laundry was all clean, I went into her bedroom to go through her drawers.
Let me describe my sister-in-law. She's about 45, never married and weighs about 250lbs. Needless to say, she is fat.
In her bedroom, she had a pile of dirty laundry in the corner. I went through them and found a few pairs of panties. My heart was racing when I brought the first pair to my nose. It had the sweetest smell of pussy, a little pee and some ass all mixed together. I stuck out my tongue and tasted them. The taste and smell was a lot like my wife's. I stuck the gusset in my mouth and continued to smell the next pairs. They all had her wonderful scent and the taste was as good as the first pair. I needed to be home soon, so I pulled my throbbing cock from my pants and wrapped her underwear around it. I had a pair in my mouth, one under my nose and pumped my swaddled cock with the other. It wasn't long before I blew a hot load in her big panties and put all them back where I found them. I still had the scent of her pussy on my lips from her dirty panties when I went home.
I can't wait until she needs another cat sitter again.
