A few months ago my aunt went on vacation and asked me to look after her house for her...water her plants and cut the lawn and so on. So one afternoon I went up to her house and went about doing what I had to do, when all if a sudden I got a sudden urge to masturbate. I guess it was the fact of being in a house all alone.
So I went to the bedroom and took off all my clothes. By this time my cock was rock hard. I continued watering her plants, completely naked and with a hard cock. Excitement kept building in me.
When I was done, I quickly went to the bathroom to relieve my throbbing cock. I looked through the hamper and found a couple of my aunt's dirty panties. I took them out and took deep smells of the crotch. I started to precum.
I took one of the panties and started to slowly stroke my cock, while the other was over my nose and in my mouth. Within two minutes I shot loads of cum into my aunt's panties.
I rolled them back up and put them back into the hamper...until next time. This happened very regularly for the two months my aunt was away. By the time she was ready to come back, that pair of panties had so much cum in it I couldn't leave them there for her to find. So even today I still have those panties at home...I think I will go masturbate into them right now.
Can't wait for her to go on vacation again.
