We've seen many different methods for stimulating the genitals using one's breasts, and this is our current favorite. No stress, no squeezing, just hardcore wanking and a pair of very large, very cooperative tits.
And everything else takes care of itself! The tits do one thing, the penis digs it, everybody has a marvelous time, and nobody's wrists get unnecessarily worn out. If only every sex position had an ergonomic alternative!
