If your erection lasts longer than...

"Three hours," your aunt said, looking up at the clock on the wall then down to your cock in the air. "You've been hard for three hours." She was standing in front of you in the kitchen with her hands on her hips. You were perched on a stool by the kitchen counter and pantsless. The erection filling the space between you and your aunt was pink and bulging. You had tried lying down, taking a shower, lying down again with an icepack in a towel held against your crotch, but the swelling would not go down.

"We should go to the emergency room or something," your aunt suggested, her voice laced with worry though she couldn't take her eyes off of your valiant manhood.

"I don't think a regular hospital will know how to deal with this," you told her. "It was an experimental **** that I took." There was the tearing sound of velcro as you removed the advanced sphygmomanometer from your arm. "Everything else is normal though," you said, showing your aunt the screen on the blood pressure monitor which was displaying a perfectly acceptable reading. She had to take your word for it. "Brynn said I should wait it out and keep an eye on my BP," you finished. Your buxom colleague seemed strangely pleased hearing about your side effects when you had called her about it half an hour ago. At least this was one of the side effects she knew about.

"Does it hurt?" asked your aunt softly. Despite the assurances that you were okay she was still wringing her hands. Offering a shrug you looked down at yourself.

"Not really. It's a little uncomfortable but I wouldn't say painful," you said. You wiggled your hips, which in turn made your cock sway, your hanging balls following in slow motion after a delay. This was meant to be funny, to show your aunt that you were okay and that she shouldn't worry, but the face she pulled was humorless. "Don't worry, Aunt Les. I'll be fine," you said, trying to comfort your aunt while you had a throbbing hard on.

"It looks painful," your aunt kept on. "All red and swollen like that." You had to agree with her there. Your veins were quite pronounced, bulging from how tight the skin was on your extended shaft. "I don't want you to be in pain," she added. Your aunt stepped closer to you, her sway slightly seductive, and only then did you realise what seeing your persistent erection was doing to your aunt's cum cravings. Almost like she was caught in a trance she reached out with her hands and grasped onto your cock. It caused a shudder to run through both your bodies. You groaned as she firmed her grip and you couldn't hide the fact that the sounds you were making weren't only caused by pleasurable sensations. There was a vague discomfort, bordering on soreness, but your aunt's soft warm fingers were mostly cancelling that out. "It does hurt doesn't it?" she asked, gently stroking you as she observed your twitchy expression.

"It's really... not that bad..." you told her, breath catching, the mixture of pain and pleasure as your aunt squeezed at you raising your blood pressure a little.

"But it could get worse," continued your aunt, now kneeling in front of the stool while still slowly jerking your cock. "Maybe we can relieve some of the pressure if you cum," she said, licking her lips. Fucking hell that expression of warm desire on her face made her the most gorgeous woman in the world. One of her hands slipped down to feel your scrotum and you sighed, the brushing caress of her fingers there completely pleasurable. "Can you cum?" she asked... her tone of voice just shy of a beg. You weren't sure. The **** was meant to increase the volume of your individual loads, but did it in turn also increase your rate of recovery? Your balls did have that familiar feeling of weight to them again... but it was hard to know if that wasn't caused by the general heavy feeling you had in the whole groin area after sporting a full erection for three hours.

"I think so," you breathed then closed your eyes. You didn't want your aunt to stop. She probably wouldn't have either way. The woman leaned forward and planted her soft lips against your stiff shaft, kissing it gently, lovingly. You had to open your eyes again and watch this and felt your heart ache seeing how she nuzzled your crotch.

"Poor baby," she cooed, either at you or your swelled cock but you didn't really care to clarify. "Aunt Les will take care of you." She did so by smothering your cock with kisses, moaning as she tasted every engorged inch of you again. Her breath and wet lips did feel soothing to your hot cock, but you were noticing a growing tenderness from the base of your piece now. You could ignore it for the moment though, your aunt's sweet voice a melodious balm. "Tell me where it hurts, baby," she sighed, looking up at you as she lapped at your testicles. "Aunt Les will make it better." There was a faint sensation you had, a premonition maybe, that you should try to cum as fast as possible, despite wanting to watch your aunt worship your cock for hours.

"The head," you directed her, your own ears getting hot as you saw your aunt nod obediently. "And use your tongue just... on the underside of it..." She looked at where you had described, her hand sliding up your rod then pressing a thumb to that perfect spot, the frenulum.

"Right here?" she confirmed, her gaze locked. With her gently rubbing her thumb up and down on the sensitive area you could only nod in response, teeth gritted. There was a dull pain slowly seeping up from the core of you erection now, there was no denying that any longer, but it still wasn't bad enough to make you want her to stop. In fact it became easy to put it out of your mind and just focus on the pleasurable sensations your aunt's gentle strokes were giving you, especially as she opened her mouth to enclose her lips completely around your plump and purple mushroom head.

"Oh fuck... yeah...yeahhh..." you grunted as her tongue began to flick your frenulum, her drool spilling over her bottom lip. She tilted her head slightly to get a better angle and your knees went weak. It was lucky you were seated. She was massaging you expertly with her tongue now and didn't forget to keep stroking the base of your cock while fondling your scrotum. She was doing everything so right you knew you wouldn't last much longer. And you were certain there was a big load coming. Her tongue rolled over the spot like magic, your breath and heartrate increasing, your cock feeling like it was getting even harder. "Aunt Les!" you called, your sensations coalescing as your being vibrated. "I'm cumming! Fuck! AAAHHHHHHHHH...AARHHHHH!" It was a yell, the cum erupting through your stodgy length too intense to keep your voice down. Pleasure flooded through your bulging genitals, sweeping away any pain or discomfort you were feeling before. Now you could only feel the tightness of your aunt's lips around your cock as you quickly filled her mouth. She was gulping quickly, almost chugging your pulsing flow, all this practice your aunt was getting starting to pay off. She was moaning as she milked you with her mouth and her hand, pumping your cock for all that you were worth. You were worth more than she could contain again, and she had to detach for a moment but she got lower and tilted her head back to catch what she couldn't swallow onto her face instead. She was closing and opening her mouth as she took down gulps of cum and air desperately, your hot jizz still spilling over her nose and her cheeks and her lips.

When she put the pulsating head of your cock back into her mouth you groaned. She sucked for more and got it, and you were still trying to catch your breath as that initial burst of vivid pleasure started to swirl down in intensity. You didn't stop cumming, your balls lurching as you gave your aunt more, and that warm feeling of wonderfulness began to fade and the soreness that you had been able to ignore before started to hum through the haze. Your ravenous aunt slurped your run off, her grip tightening as she squeezed more ready seed from you and the pain started to bloom, washed over by residual ripples of pleasure but returning stronger after each pulse.

"Stop stop..." you groaned, throat feeling dry, your aunt's attention now a little too much. She didn't seem to hear you though and just moaned as she felt more of your cum slide down her throat. "Aunt Les... please stop... please..." you whimpered, putting a hand on her head. Finally that cut through to your aunt and she released you, reeling back slightly as if she had regained her senses after zoning out.. You looked at each other, your face with a smile hanging off your painful grimace, hers looking soft and satisfied, drenched in your excessive load. Your cock was still hard.

"Oh John," sighed your aunt, noticing this and getting to her feet. "Oh no, it didn't work..."She looked to have sobered up a bit seeing that your 'condition' hadn't improved. The crease in her brow was still visible beneath your thick and gooey load. You inhaled deeply then exhaled all at once, the breath making you feel slightly better for a moment before that dull ache in your diamond hard and now redder cock returned. This might be a problem.
