Summer Sinn once gave us a tutorial about handling her tits. And handling those tits is a major challenge, not for the faint-hearted. "Lick them and suck them," Summer instructed. "I like it. Softly, because they're sensitive. Don't bite them. I'm not into domination. Maybe start out by licking them a little, then sucking them a little, then licking them, then sucking some more. Pay lots of attention to them. Go from one to the other.
