What I think would be the most erotic, sexy, sensual thing would be for some lucky guy to stick his hard cock into a large bun and fuck away until he cums. There have been many pictures here of large buns that seem to defy gravitiy by their strong construction. The girl could gently hold the bun, the man could gently hold the bun, but the man would just thrust in and out of the bun until he cums and hopefully we would see the cum leak out of the bun while he's still in the bun.
