Tongue only, no hands

"Just the tongue should be sufficient I would think. You have 5 minues. Go." Suzanne states plainly. She clearly likes to keep a tight schedule for her employees and John knows to take her seriously. He looks at you pleadingly as you begin to give the huge cock a through tongue bath from root to tip.

"Oh come on, Suz! I won't be able to get off from something like this! Especially not that fast!" John exlaims, now gaining full hardness from your slow licking. He's at least enjoying your work, even if he's complaining. He tries to grab his cock to jerk it while you lick, but she stops him.

"Are you insulting this young lady's ability to get her own donation? No touching." She says, as John continues to whine. You make sure to get every inch slick and dripping with your saliva, not just concentrating on the head, infuriating him further. "4 minutes left!"

He begins to panic more upon hearing the time remaining, watching you work with a pained expression that cries for you to move faster. You relish slightly in your **** for the previous rough treatment, slowly circling the giant head with your tongue. He thrusts forward uselessly to try to get more stimulation, but only serves to throw off your rhythm.

"Come on, sweetie. You're going to have to do better than that if you want me to cum soon! My job is on the line here!" He yells at you in frustration. You enjoy having this much control over your own donations for once, carefully tracing the underside of the long shaft with small swirls as he groans further.

You decide to even work the balls a little, causing another noise of pleasure and irritation as you work your way underneath. You juggle the huge testes on your tongue with loud slurping sound until they are dripping wet. This is kinda fun!

"3 minutes."

He lets out nearly a cry of pain upon hearing the time again, and you decide to take slight mercy and at least concentrate on the more sensitive top so he has a slight chance to make it in time. Now fully and painfully hard, you lap at the edges of his flared, pulsating head like a kitten with milk. He clearly feels fantastic, but is nowhere near getting off any time soon.

"At least let her use her tits or something! This isn't fair!" John shouts at Suzanne, who seems to be stifiling laughter over his oral ****. You try not to laugh as well.

"That's up to her! Maybe you can ask nicely. Just 2 minutes left." She states with a smile.

He looks down at you pleadingly as you continue your long slow tongue job. You decide to take mercy on him since more than half of the time has elapsed already. You sit up slightly and wrap your tits around the thick shaft.

There's barely enough breast meat to cover the whole thing, but your extensive tongue bath has left it slick enough to slide between them easily. You work your spit soaked chest up and down the giant tool while continuing to lick at the head, pointed ominously at your mouth.

Unfortunately for John, your only real tit fuck experience is from your brother, and that's just him waking you up regularly by sitting on your chest and viciously humping them, pounding at your sleeping mouth until you wake up enough to open it for him. Then he just fucks your mouth until he cums and leaves without saying a word. You don't usually have to do it yourself.

Your inexperience shows clearly as you awkwardly slide up and down the pole while still trying to keep your tongue moving over the head. He somehow seems to be getting even less from this, mostly since you can't get a good rhythm going, practically leaving the most sensitive part untouched as you struggle with the shaft between your tits.

"One minute!" Miss Lovegood yells to practically the whole cafeteria. John looks extra worried and you start feeling bad about your subpar performance about to cost him his job. You decide to take pity and stuff the whole head in your mouth, despite it barely fitting. You managed it this morning.

After practically unhinging your jaw, you stuff the huge thing inside at great effort, leaving barely enough room to maneuver your tongue. The tight fit makes the movement more difficult, but the effort at least seems more appreciated.

"30 seconds!"

"Oh, screw it!" John exclaims, now figuring he was going to lose his job at this rate anyway, so he might as well do whatever he can to get off, even if it breaks the rules. He squeezes your tits harder around his cock with his thighs as he grabs the back of your head with both hands.

You have barely a moment to react with a small squeal before you start a squelching gag as John begins hammer fucking the entrance to your throat. There's no way the tremendous thing would bend enough to penetrate very far, but he feels like he's trying to break your neck shoving your face deeper between your tits to try.

Miss Lovegood begins a countdown of the remaining time as John uses more and more **** in the attempt to get down your throat from the bad angle. He jerks your head roughly by the hair while matching a thrust between your crushed tits with each pull of your neck.

You can do nothing but heave and struggle against his brutal ****, attempting a scream around his dick and into your chest. A waterfall of gagged up saliva provides better and better lubrication as he quickly approaches orgasm.

Her countdown begins to feel more like she is counting down to his orgasm as she nears zero, each thrust getting harder and deeper as she goes. Perfectly on cue your mouth and throat suddenly spill over with a sudden giant load. He's not deep enough to shoot it into your stomach as he had before, now showing you exactly the size of the doses provided by his huge balls as you desperately try to swallow.

John lets go of your pained tits with his thighs as Miss Lovegood lets out a small laugh of triumph. She holds her empty glass under your chin to catch the missed cum as it drips down while John continues to milk his orgasm with sharp yanks of your hair. You swallow as much as you can, but the overwhelming amount flooding your mouth causes you to lose move than half.

John releases your hair and you back up with a sharp intake of breath, a long thick strand of cum and spit still connecting you to the dripping cock. Suzanne sucks this up immediately, licking up as much of the missed medicine as she can before you can react.

"What do you say, Johnathan?" She coos at him.

"Thank you, Miss Lovegood." He says, defeated and hoping she leaves him alone. She looks at you like she expects you to say the same.

*Cough*"Thank you" *cough* "Miss Lovegood...." You manage after you catch your breath. She releases him to scurry away and finishes scooping the cum off your breasts into the glass. She looks at it like she expected more.

"Hmmm, how shall we get more then?"
