When his hand goes between my legs I'm more than ready for him. We peel off each other's clothes with more urgency than usual, aware that this is the last time for seven days. We lie on the bed for a couple of minutes, just kissing-that's all he has to do-and before he's even touched my clitoris, I'm spreading my legs as wide as they can go, showing him my soaking slit and telling him how much I want him. And then he's in me, filling me up like no one else can.

Let me tell you about Mark's dick. I don't know quite how, but it's as if it was made for my body. The first time I felt him inside me, it was like I was complete for the first time in my life. It's a pale biscuit color, and it stands upright above two smooth, even balls. It's long, but what I like best about it is its girth: every time he presses against my pussy with that smooth, rounded head I know he's going to be inside me, stretching me pleasantly, moving around and probing every inch of my cunt.

And that's what I'm feeling right now as my pussy muscles hug and massage his hard-on. Mark pulls out a little bit and drives into me with a force that borders on aggression because he knows that I love, live for, those moments when he first gets inside me. He does this for maybe two, three minutes, watching my face, reading the signs of my body. He knows just the right moment to trip me over the edge into my climax with his finger on my clitoris. As I reach my orgasm, it's bittersweet, and my contractions force him to come, too. We hold each other for a while, drift off to sleep with sticky sheets and limbs, smelling of each other's bodies.

When I wake up it's four a.m. and Mark is packing his case ready for his early-morning flight. He leans in and kisses me good-bye. I show him that my nipples are hard and reach for his cock, but he shakes his head; there's no time. Last night's fuck should have me satisfied for the lonely days ahead, but on the contrary, it's just left me more frustrated. Mark's dick is addictive: the more I have it, the more I want it and need it. I hear the door close behind him and manage to grab another couple of hours' sleep.
