Oral Practice

Crystal looks at you unsure but nods yes slowly.

"I knew you would, you are always so ready to learn and share," you say as she looks over at your exposed cock hanging out. It was not very hard at the moment and fortunately you are a grower not a shower as she is about to find out.

"It's not as big as the girls say they are" she says reaching out and touching it very gentle as if she is afraid she will break it with just a simple touch.

You just smile as she opens her mouth and puts the head between her lips closing them around it and sucking slightly. Your cock grows slowly inside her mouth moving into her warmth thickening as you just hold her head keeping her tight enough to feel it swell inside her mouth.

You do not pump or cause her to fear it as it grows thicker slowly and to help it grow you reach down and unbutton her blouse and rub her pert A sized breast through her clean cotton bra cup.

It only takes a few more moments for her to realize not all cocks start off as big as they can get as she is pushing on your thighs trying to release your cock from her mouth, her lips stretching open as she breathes in air but it is blocked off as your cock bends down inside her throat.

Feeling her nipple push at the bra cup you trace it and she moans and then gags as your now full sized cock grows past her throat and burrows deeper down inside it.

Finally you slide back, her gagging and saliva dripping off your cock as she stares at its girth and length with wide teary eyes.

"That is huge" she says looking at it in both fear and fascination.

"Again" you say pushing the head at her mouth and she opens her lips wide and allows you to push it inside her face, her tongue a bed for it to lie on as it is pushed deeper and deeper until the head of your cock is rubbing the roof of her mouth just before it bends down again into her throat and once more you hold her there firmly not humping her mouth but once more rubbing her pert breast through her bra cup.

Crystal jerks against you as she gags and you let her breathe again as you pull out of her mouth, the spittle falling down her chin this time.

She looks at you, confused at first and then it is as if she understands until she sucks you off she cannot leave. With her knew understanding she grips your thick shaft and holds you firmly as she pushes her own head down onto your thick purple cock head and then sucks it in deeper and deeper forcing her own face down as she twists and turns on it trying to get it all the way inside her throat.

Sliding your hand down you push your fingers into the cup of her bra and feel her hard nipple pulling and pushing it against her soft flesh until she once more is gagging and backing away from your turgid hardness.

"I am impressed" you tell her "that you are able to put it all the way down your throat with practice I am sure she will be able to take it all every time."

Now she is determined and she thrusts her head down gagging each time your cock impales itself deeply into her mouth before she closes her lips on your shaft sucking and forcing it deep as you continue to tweak her nipple again and again.

Reaching up with your free hand you pull her face tightly against you as she jerks and spasms on your shaft until you let her go and she looks up at you with tears in her eyes.

"That is probably enough, don't you think" you ask her?

She looks ashamed and you feel for her so you decide to smack it on her face until she opens her mouth again and then you show her how to hold and stroke your cock wile sucking on the head comfortably.

She is smacking and sucking and licking now as she strokes until the final bell sounds and my cock erupts filling her mouth with my thick flow of cum.

She spits and wipes her mouth backing away. Then stands buttoning her blouse.

"See you later Crystal" you promise as she runs from the room for her next class which you are sure she will be late for.
