The 2 times I have jacked with my step-cousin has really given me an appreciation for small ones. He is quite small -- I have not measured it but I would say no more than about 2.5 inches and very thin. It really excites me because it makes me think of the times I jacked with my step-uncle when I was quite young, except in reverse. I think I will have a bate session now and think of his beautiful, small dick!
