Only with great difficulty

For a moment, Jie's rapid and firm tongue movements remind you of a rabbit eating a lettuce leaf, then she changes to slow, sensuous, swirling licks that slip between labia and circle Léa's clitoris in a figure of eight, before she opens wide to seemingly try to suck the whole of the blonde's sex into her mouth while probing deep inside. Each progression serves to heighten your guest's arousal and when the quick clit-licking resumes, she can't suppress a whimper of desire. She shudders and a rosy glow suffuses her angelic face and a chest heaving with deep breaths. You realize that Frenchwoman does not easily blush from embarrassment, although since the two of you have become involved, she's experienced plenty of that, but arousal is a different matter. She closes her eyes and moans involuntarily, while Jie switches to swirls again, slightly less slow this time, but equally sensuous.

Léa's hands jerk by her sides, as though seeking something to grab onto and she thrusts her chest out, throwing her head back and panting passionately. You'd love to stroke her shapely tits and roll her stiff nipples between your fingers and can't help think she'd probably enjoy it too, although she wouldn't thank you for making it even harder to control her climax. The Asian student at her feet doesn't maintain the cycle of techniques predictably, sometimes doubling back or adding in something completely different, making it even harder to hold back and the lectrice is scrunching her eyes shut and whimpering through tightly compressed lips when Jie spins around to face her, never losing contact between mouth and cunt.

Now with her face upright, your grad-student uses the different angle to great effect, looking up towards the face of the woman riding hers, trying to gauge the best way to **** her to the brink of orgasm. It doesn't take long to achieve, as Léa's thighs clamp on Jie's cheeks and her knees buckle, relying upon the younger woman for support. Her hands shake whilst her arms move jerkily, as though she can't decide whether to push the other woman away or grind her to her crotch. She's spared the decision, however, since Jie's not going anywhere.

You watch the drips of perspiration running down your guest's torso while she moans in frustration and need, feet twisting on the floor as she writhes against the girl kneeling at her feet, the scent of her passion pungent and unmistakable even over the aroma of the meal nearing readiness in the kitchen nearby. Suddenly, her eyes shoot open, along with her mouth and her breath catches in her throat. For what seems like an eternity, she shudders at the very edge of climax, a low whine emanating from deep within her chest and panic rising on her face, then, just when you're sure she must break contact with the skilled nymph squeezed between her thighs or succumb, the Asian girl withdraws her tongue and uses it to speak instead of impart exquisite pleasure.

"I'm sorry, Mademoiselle, but I need to serve the dinner now."

"Oh, yes, uh, of course, Jie," the lectrice gasps in ill-concealed relief, trying unsuccessfully to get herself back under control. Eventually, she uses her hands on the top of the student's head to push herself upright, although she's still a bit shaky and presses her palms to her cheeks in an effort to calm her raging libido. Jie doesn't exactly help when she darts in again, to lick the two thick streams of juices from the blonde's thighs, then quickly rises and departs with a curtsey.

When her panting slows and she can finally speak coherently, Léa smiles at you and you hand her back her wine while she whispers so that Jie can't hear: "Well, Jaques, that was considerably more intense than I expected."

"Most enjoyable to watch, though," you respond and Léa, taking a deep drink, almost splutters in surprise, but you're sure you catch a look of appreciation from the lovely young woman standing naked and overstimulated in your hallway.

Before things can go any further, Jie returns, having cleaned her face of Léa's intimate fluids in the meantime.
