When I climbed back on the bed, it wasn't to get between her spread thighs, but at her head. I ran the leaking tip of my cock across her lips, back and forth until they were covered with pre-cum.
"Taste me, lick your lips." I waited until her tongue had cleaned every vestige of pre-cum from her lips before dipping my cockhead into her mouth. She jumped at first at the unfamiliar, but soon settled down.
I led her by moving my cock back and forth making sure not to go too deep too soon. I fed her just a few inches and watched her lips stretch as she tried to swallow. "There's no way you'll ever be able to take all of me in your mouth so I won't even try. Relax."
