After about an hour, we were having a great time, but everyone still felt like a little cock would do the trick. None of us could think of anyone at hand, till Tina jokingly suggested Marc, my younger step-brother, who had just turned 18. At first we kidded about it, since Marc is quite short and had always seemed so young and immature. But then we began to take it seriously.
Marc was in the basement family room, and Tina suggested we each spend fifteen minutes with him wearing sexy clothes, but not doing anything, except letting him watch and hopefully getting him turned-on.
