Cock Ring and Panties
I put a cock ring vibrator on my cock just behind the knob. Once I am hard, I get hold of my sister-in-law's panty's I stole from her washing basket, have a few good sniffs of her pussy juice, and begin to rub the underside of my cock, side to side with the crotch just behind the vibrator. Watching a slide show of some pics I have of my sister-in-law, scattered with some great pussy pics, I have the greatest orgasms I have ever had...
