Take her ass

You pull out of Jean's throat and she gives a shuddering gasp of relief. Her hips are rocking against Gavin's final thrusts as he drains his balls into her, groaning with pleasure. As he finishes he slumps down over her, kissing her tiny breasts. She wraps her hands around he neck, stroking his hair.

"You're my third," she murmurs happily. Gavin slowly extricates himself from the clinging, slender girl and stands, smiling at you.

"Is her throat as tight as her cunt, John?"

"Very nearly. I want to make a third comparison," you answer, gesturing to the blonde waif, who lays sprawled on the desk, humming happily, her hair and her arms spread wide. Gavin looks at your swollen cock and glances at the oblivious girl, smiling and nodding approval as he steps out of the way.

You step forward and gently roll her over onto her belly She makes a brief murmur of protest, but as she feels you stroke her well fucked pussy the murmur turns into a purr, and she rubs back against your hand. Gavin walks around the desk, and presses his slowly wilting cock to the slender blonde's lips.

"Clean me off child," he orders in a kindly voice and she obediently laps the mingled pussy juice and come off his cock as your hands probe her, rubbing her mingled juices upwards into the crack of her ass, pressing a finger into her tight rosebud.

She gives a muffled squeak of protest, but you ignore it, thrusting your finger deeper into her ass. She tries to pull off Gavin's cock but he holds her shoulders, trapping her in place, smiling at you.

You pull your finger out of her and her tense body relaxes for a moment until she feels your cock pressing against her puckered hole, remorselessly invading it. Her slender legs flail in protest, doing nothing but drive her deeper onto you.

"Relax and enjoy it Jean," Gavin says, holding her down and stroking her head. You reach up and grab her pony tail, tugging it tight as you slide the last few inches of your cock into her virgin asshole. Her back arches, her head snapping back on her neck, her mouth open wide in a silent scream as she feels you buried deep in her.

You start to thrust slowly, reaching a hand beneath her to rub her clit. She starts a series of deep shuddering gasps, her body trembling with each of them, and you realize that she's coming, her tight young muscles squeezing your cock, sending you over the edge, spurting cream up her ass, burying your cock to the balls in her slender, willing body.

Finally drained, you pull your cock out of her tight hole. She lays across the desk, come dribbling out of her. Her eyes are closed and her hips rock gently. She nibbles at one hand with her lips.

With a hearty grin, Jim Gavin starts to straighten himself up. "We really have to do this more often, John."
