My step-sister Jessie is really hot, I sometimes beat off using her underwear, I guess she found out cause the other day I got this video from her. She doesn't want me to be jerking off all over the place and would rather help me so than get me in trouble. Jessie tells me how to jack my dick, she shows me using her favorite dildo how she makes a cock cum. Jessie wants to see me cum, she encourages me to go faster and starts a countdown for me to cum... I explode everywhere from my step-sister telling me when to cum.
