"...sort of equipment!"

"O... Okay..." Sarah says, licking her lips nervously while watching your hands reach down and slowly start unbuckling your belt.

Your cock feels harder than ever as it strains against it's confinement, and you grunt in relief while finally releasing the pressure by unbuttoning your pants and pulling down the zipper. Looking right at Sarah's beautiful face, you can clearly see the look of shock and amazement in her bulging eyes as you slowly fish up your incredible hardon from your boxers!

"Ohmygod...!" You hear her whisper to herself as you give your fat eight incher a few strokes with your hand. She keeps staring for quite some time, before reluctantly lifting her gaze from your crotch, looking into your eyes while her cheeks start to blossom scarlet red.

"A... Are you su... sure you'll get a better reading wi... with that...?" She wonders, just barely managing to get a little of that pretended innocent tone into her voice.

"Yeah, definitely!" You tell her reassuringly. "It's a lot better for readings like this. Much more sensitive!"

"O... Okay..." She nods acceptingly, daring another glance at your impressive equipment while nervously biting her lip. "It's just that... it's... a little b... big..."

"Oh... Well, I'm fully confident in your abilities, Sarah!" You tell her, caressing her blushing cheek and luring a little giggle from her as you use the same words as she did herself not too long ago.

"Well, thank you, Dr.Doe." She says, most of that mischievousness having returned to her big brown eyes as she looks up into yours. "I'll give it a try at least!"

Smiling at her in astonishment, you catch a pillow from the couch and place it on the floor right before her feet, then hold her hand to help her keep the balance while she's kneeling down upon it. Your cock twitches in anticipation as her head comes in level with your hips, making the young beauty giggle a little while staring fascinatedly at it from her new position.

"Now you simply do just like you did last time..." You instruct her, looking down at her sweet face as she slowly part her delicious lips and once again stick the tip of her tongue out for you! Even though you're more than eager to continue right away, you hold yourself back for a few moments, sharing a long, questioning look with Sarah until she slowly nods her head, signalling that she's ready, and even willing...!

Nodding back, you slowly step forward and, as gently as possible, place the tip of your big, purple and swollen cock-head to the girl's soft tongue! You rest there for a few seconds while still looking deep into Sarah's eyes, both of you breathing heavily in excitement, and just enjoy the feeling of her hot breath caressing your throbbing member.

Having waited for this moment for far too long allready, you slowly start to press forward, watching Sarah's luscious lips spread wider to accept your girth. The feeling is incredible as she wraps those lovely lips around your shaft, and you have to fight hard to remain in control of your own body! The last thing you want right now is to come too early!

The girl does seem to have a little problem handling the sheer amount of meat entering her little mouth, and you feel her teeth scratch your sensitive skin as you press on, but she handles it well and you watch in amazement as the entire head of your thick member disappears between her wonderful lips! Slowly pushing onwards, you feed her almost half of your long shaft before she seems to reach her limit.

At this point she reaches up and gently wraps her hand around your massive member, mostly, you guess, just to keep you from trying to go further than she can handle. Accepting, you hold completely still while feeling her lips clamp down even tighter around your cock and her tongue press against it's underside as she gently starts to suck on you! Still looking up at you, with her lovely doe eyes, she then starts to make small movements forth and back, massaging almost every bit of the four inches of cock inside her mouth!

This goes on for more than a full minute, and you're quite surprised that you manage to hold yourself back from climaxing for all this time! Her sharp teeth and quite inexperienced techniques play a big part to this, but you've no reason to complain since you can remain focused on the action without having to think about something else to keep from cumming!

Then she suddenly pulls back, letting your cock spring free with an audible plopping sound. Thin strings of saliva and pre-cum keep connecting you to her lips for a few seconds while you're both gasping for air, before they break and is left hanging from her lips and chin.

"You okay...?" You ask her when you've managed to catch your breath. You hadn't realised you'd been holding it for almost the whole time!

"Y... Yeah!" She replies, as much out of breath as yourself, giving you a mischievous smile while cleaning her lips with her tongue. "And you...? Have you got a reading yet?"

"Not quite." You tell her after only a few seconds of confusement before you remember the playing-the-doctor game. "I'm afraid you broke off just a little too early!"

"So we'll have to start over from the beginning then?" She wonders, trying to sound disappointed even though her big grin and glimmering eyes tell you quite another story!

"I'm afraid so..." You answer her with an apologizing smile.

"Okay... And how should I know when it's done?" She queries while leaning closer, her lips brushing against your slippery cock-head!

"You'll... notice..." You tell her, reaching down to caress the back of her head while a deep groan escapes your lips.

"Oh?!" Sarah giggles, letting her tongue caress the underside of your throbbing member. "And you're sure I'm doing it right? Sometimes I'm afraid my teeth could damage the equipment..."

"You're doing just fine!" You assure her, but then notice the serious look in her eyes. "I mean... You're doing great, but I guess you could be a little more careful with those teeth..."

"And...?" She wonders, pulling back a little while looking up at you with her big doe eyes.

Well... If she really wants to get a lesson in giving head, you can't really deny her one, can you? So... What do you think she needs to get better at?
