You make Johanna tip you with her throat

"Take off your jumper and deep throat me," you instruct the unfortunate lesbian.

"Yes, Professor," she replies, successfully masking any hint of distress at her coming fate. She tries to get off the table and immediately stifles a scream as her burning bottom rubs on the tabletop. You help her out, putting your hands under her armpits and lifting her up in one motion, setting her safely on the ground. She thanks you and pulls her top over her head to reveal a tight, toned abdomen and a pair of very pretty little titties. While she neatly stacks her clothes on the table and smooths her long hair back into place, you wonder briefly whether her blush earlier was in part due to being so much less well endowed than her colleague, then your lust drives all other thoughts from your head, so you drop your trousers and sit back down in your chair, your prick jutting upwards obscenely.

The Asian youngster kneels gracefully at your feet, opens her mouth as wide as she can and sticks out her tongue to guide your cock head inside, immediately closing her lips tight around your clammy shaft and starting to suck. She slides up and down a couple of times, her cheeks hollowing, then pushes forwards, trying to take you right down her gullet. She gags and retches slightly when you hit the back of her throat, but she forces herself to continue, swallowing repeatedly in an effort to progress. Realizing that she seems to be having trouble, you decide to help her out and put your hand on the back of her head. It only takes a small amount of pressure to finish the job and soon her lips are secure around the base of your prick.

You keep your hand in place, not holding her down by ****, but letting her know that you want her to remain with her nose pressed into your pubic hair a little longer, savouring her increasingly **** heaving and gagging. She resolutely stays down, struggling against every reflex of her own body to comply with your demands, until you release her and she rears back with relief, your dick, now slick with her spit, popping out of her throat, the tip remaining in her mouth. She gasps and then repeats her previous action.

This time, she manages to envelop you totally, with difficulty but without assistance, then starts to slide up and down, slowly at first and then gaining speed, looking up into your eyes in an attempt to gauge your response. She never tries to use her hands for extra stimulation, either having been trained that way or guessing that it would displease you.

As she gags and fights for breath, her head bobbing on your pulsating member, your passion rises, increasing in intensity. Grunting in lust, you grab her by the hair and slam her face down on your prick over and over. Finally, she manages to suck you to fulfilment and moans with relief as you fill her throat with your spunk. She doesn't rest however, continuing to squeeze your manhood with her plundered gullet until she has milked out every drop.

Although her performance was not entirely flawless, you can't deny that it was a truly great blowjob, especially considering your student's sexual orientation.
