I got a voice mail message on my phone from my sister-in-law asking me to feed her cat again. When I arrived at her place, the dish was full already so I took a look in her bed room and I found a pair of white cotton panties folded on the bed with a note, 'Have fun!'
So, I figured out she wanted me to cum in them again, so I took off my pants and sat on the bed. My cock got hard thinking of her lying in bed naked. I grabbed the panties and wrapped them around my cock and started stoking away.
I walked around her house naked while stroking my cock. I sat in her chair stroking when I felt that loving feeling, so I hurried to her room and instead of cumming in her panties, I thought I'd give her a real surprise.
I grabbed her pillow and got ready to cum. I layed my cock on the pillow and shot my cum across her pillow case; three white jets of sperm. I cleaned up, but this time, I took the panties and put them in my pocket so when I want to jack off, I will have her panties to do it with.
A couple of days later, I got a voice mail thanking me for feeding her cats, AGAIN.
