I've always liked to masturbate, with my wife or on my own. Recently the lady across the road has been having students stay for a couple of weeks, now their bedrooms face our house and late at night as they get ready for bed you can see in and being older students some don't care and I have seen many breasts.
When my wife goes out I leave a big enough gap in the blinds and turn the light on so they get a good view if they look over, then I wait in the other room to see when they are looking out all the time making sure my cock is hard and wet. When I see them I walk back in and start pulling my cock back and forth knowing they are watching me and looking out the corner of my eye to see if they are still looking.
When I know they are I lean against the bedroom wall and wank my stiff cock and pinch my nipples hard. It doesn't take long before I pump out loads of cum. I rub it all over my body and keep wanking till my cock is hard again. I do this when ever.
I can't wait till more students come. My cock is hard now, I'm going to wank in the garden now, that's another story to tell soon.
