She blows you

"This is how I got every job I've ever gotten in this town," she tells you as she begins to suck your dick, having freed it from the confines of your pants.

"MMM...I believe it Kristen..." you tell her as you run your fingers through her hair and push her further down onto your dick as she happily slurps away on it.

"FUCK...that feels good..." you moan, throwing your head back against the wall as she blows you, taking extra care to cup your balls and take one up into her mouth every now and then.

"UH...YEAH...suck it Kristen..." you tell her as you start to feel your balls fill up with cum, her hands working them over as she draws you closer to orgasm, smiling up at you as she momentarily slides her mouth away from your dick.

"Cum for me and I'll let you cum in me later John," she teases you as she wraps her hands around your dick and starts to suck it again, bringing your balls into her mouth one last time as you grab her by the back of the head and **** her to take all of your dick down her throat.

Why even try to hold out now, you tell yourself, when Kristen just guaranteed she'd fuck you if you came for her.

"Here it comes Kristen," you tell her as you give her a few thrusts of your hips and moan as you feel your cum rushing up your dick.
