Pay closer attention to her breasts.

You shift your hands, starting to unbutton Sarah's blouse from top to bottom. She doesn’t object; she merely lifts her chin and lets out a happy sigh as you nuzzle under her ear. Soon you have the last button undone, and she helps you to remove her blouse, shrugging her shoulders and twisting so that you can draw it off her arms and let it fall.

She leans back against you, letting you look over her shoulder and down her chest. Her bra is flimsy and cut very low, giving you an excellent view of her full, round cleavage. She holds her breath as you find the fastener of her bra, back between her shoulder blades. With a little fumbling, you have her bra loose, and soon it joins her blouse on the floor.

Her breasts are perfect: smooth and generous, and her nipples are plucky and erect. When you slide your hands back over her bare breasts, she shivers and moans. When your fingers find her hard nipples, she sucks in a breath and arches her back. “Oh, John, that’s so nice …”

She covers your arms with hers, putting her hands over the backs of your own, encouraging you as you tease her nipples. She wriggles in your lap, twisting and rubbing her crossed thighs together, pressing against your cock and giving you the almost overwhelming urge to turn her over your desk and bury your shaft in your pussy. But no, you can be patient, and there’s something so fantastically erotic about having this gorgeous young girl moaning in your lap, responding to your every touch.

When you shift your head to nibble at the other side of her throat, she shivers violently, clutching at your wrists. “Oh, god,” she begs, “don’t stop, oh, please...” Her shiver turns into a tremble, a vibration that takes hold of her entire body, from her toes to her hips to her breasts to her shoulders. Her breath catches abruptly, and her hips give a sharp twitch, and another, and...

“OHHHhhh!” she shouts, her entire body jerking in your arms. Her thighs fall open, and she tosses her head back, moaning and gasping, hips wiggling, feet kicking at the floor. Just how you manage to avoid coming in your pants right then is a miracle of willpower.

After a few frantic moments, she starts to subside, drawing in a long, ragged breath, and going limp in your arms. “Oh, John … I think I just came.”

“Mmmm...” Sarah covers your hands with yours again, helping you to cup your breasts. “I didn’t know I could come like that. I guess I was pretty horny.”

“You were incredible,” you say, kissing her cheek.

She sighs. “I want to make you come now,” she whispers. “Whatever you want. However you want me.”
