Missionary

He looks worried, saying "Are you sure? I've never done this before, I might not last that long. Especially if you're fertile."

You tell him that it's okay. "Just enjoy the moment, its going feel so good" you say, using your legs to pull him into you. He resists for a second, but as soon as the tip of his head touches your bare pussy, his self control fades away. Even with just the tip grazing your entrance, you can feel how much more texture and detail there is to the sensation.

He slides his head into you, his eyes almost rolling back. "Oh… my… god…" he breathes, pushing a little bit further with each word. He's about halfway inside of you now, and you nudge his back again, asking him to give you the rest. "Please, just fuck me," you say, squeezing your muscles around his length. "You feel soooo good" he moans, finally hilting himself inside of your warm, wet pussy.

He kisses you deeply as he savors the feeling of your raw pussy tightening around his bare cock. "I… intense…" he whispers as he starts to slowly pull back. He gets about halfway back before exclaiming "fuck!!!" as he slides back into you, his legs almost giving way.

"Are you gonna cum?" you ask, almost smirking about how good you make him feel.
