My first GF showed me this tech after she had an affair with an older man. He showed her how to jack him off while pullng down on his nuts. After I'd gotten over my shock she me how good it felt while she stroked my cock....I wasn't so upset after this experience...mmmmm
And I tried it again after being remind of it here.....I was in the shower jerkin off while tugging on my swollen balls.....I sprayed so much cum.....I almost collapsed in the tub......very nice!!!!
