I am not into the sucking right away.
I need a soft tongue on my clit to get me going. I like it when my bf spreads me really, really slow and licks the inside of my lips and rings my vag, not going in, just teasing.
When I get more excited, he makes his tongue hard and pointy and licks me fast and slow. He alternates. He'll suck my clit into his mouth and lick it at the same time. The heat and wetness of his mouth drives me crazy. He doesn't suck hard though. While he does this, he will be touching my opening, teasing me, making me beg him to finger fuck me.
When I tell him I am about to cum, he keeps the pace the same, the amount of pressure the same, plunges his fingers inside, fucks me hard and rides my clit with his face to orgasm.
