testing your limits.

you start by massaging her log of a cock, even semi-aroused it's over a foot longth and it only continues to swell. You lick the thick precum coating her, you enjoy the salty cream like essence of it. Your mouth begins to painfully stretch around her as she grows hard. She bodily lifts you up, never letting your mouth come free of her member.

"Here we go!" She gently sets you down on a low work bench that allows her to easily thrust into you while standing. You shudder as she begins pushing her massive length down your throat, you struggle to breath through your nose as she chuckles girlishly.

"Goddess I missed seeing a throat get reshaped by my cock! Good thing you don't have a choker!" She laughs and pushes more into you. It feels she is reaching into your soul as you can only twitch in response to her swollen testicles gradually moving towards your face as you lie on your back. You snort and cough on her cock when she finally hilts into your gaping maw, her balls firmly planted on your face, forcing you to take deep breaths of her musk. Soon the room fills with the wet sounds of her vigorous thrusting into your mouth. Her 18" log pumping more if her thick pre along your passage, the taste if her soaking through your thoughts as your hips, unconsciously, buck and strain.

You try to suckle more on the massive tool spearing you as she coos.

"If you keep up your work in my class I might just have to reward you more often, ugh, perhaps we can make a model teacher's assistant out of you." Her sentence punctuated by deeps plunges. Your head begins to spin, from lack of air or her intoxicating cock drool you aren't sure. One of your hands finds your own cock and to your muzzy headed surprise it is limp.

"Oh yes, I forgot to mention, that relaxer also stops erections, only way you get to release is from alternative stimulation." She chuckles as she begins to piston her wide hips faster.

Your hands move to grip her supple flesh as her lunges become **** to build to the climax.

"That's a good boy, I'm gonna take. Good. Care. Of. You!" Each word followed by her slamming against your face. You feel the tell tale clench and swelling along her length before a torrent of warmth floods your stomach. Her cum flooding your mouth. You hazily try to gulp as swallow as much as you can while she slowly pulls out of you until you lie, bloated and delirious, nursing her cockhead for more of her creamy cum.

She smiles sweetly at your prone form.

Your entire body tingles and you lie, sated and boneless, as a few more spurts seep into your mouth.

"Not a drop wasted, either you are quite attentive..." she leans down and gently rocks her tip against your tongue.

"Or you are an insatiable cumslut." You groan as your belly painfully sloshes, full of her orgasm.

"Well, that was quite enjoyable." She finals pulls free of your vacuum sealed lips.
