Impatience part I

‘... and so in 2005 with a study in simian behavior involving common marmosets and cottontop tamarins, animals of both species were faced with a self-control paradigm in which individuals chose between taking an immediate small reward and waiting a variable amount of time for a large reward. Under these conditions...’

Selanine’s scarlet eyes glazed over, her already limited focus slipping from the lector’s PowerPoint presentation. The equine had seated herself among the back pews in the auditorium, hoping to avoid being questioned during the lecture. Leave that to the poindexters, she’d thought. She was slumped forward over the desk, her prodigious tits pillowing as she rested, chin in hand. More than once, this behavior had attracted her attention - several guys in her class stole glances (and to be fair, she’d bedded a few of them too for the fun of it) but something else entirely consumed her attention now.

Several times during the lecture, her hand had wandered to the pocket where she kept a small golden ring, topped with a fiery opal. Recently, it had been gifted by her current lover and close friend: Kyera. The skerpent had captured Selanine’s attention, so much so as to make Sel put her cross-country tour on hold and sign up for a semester at the community college, just for an excuse to stick around - not that Sel would ever admit that was the case.
The ring, Kyera had demonstrated, was magical. It was imbued with some of the draconic magic inherent to Kyera’s species, and it gifted the wearer with transformative abilities. Naturally, Selanine’s first instinct had been to use these powers for sex - which had only made her insatiable appetite grow. 
The guys bored her - none of them could really stimulate Sel (her equine endowments meant that their pricks were all but lost in the spacious folds of her vag) and few of the girls could accommodate Sel’s girth. Kyera however, was a herm like Selanine. Gifted with both lovely, large breasts; a strong and warm cunt; and a huge, thick cock that rivalled Sel’s own.
‘Rgh... snap out of it...’ Sel muttered to herself, shaking her head sharply. Thinking of Kyera had brought the familiar tingle of arousal, making Sel’s pants tighten and moistened her nethers. She noticed that the ring was now on the desk, a slender yet strong finger pushing it about absentmindedly, resting within its periphery.

‘The ring will crank up your lust and your sex-drive, Sel,’ Kyera had warned when she handed it over, ‘It will take getting used to, and if you don’t practice under supervision, you might find yourself in over your head. The ring also came from my essence so...’ the skerpent had blushed at this point, ‘it also holds my attraction to you... that’s how I managed to key it to only you but... this means that it wants to turn you on... and it doesn’t care about when or where. It is always horny... and it wants to do the same to you.’

‘Always horny huh... I can relate, little buddy...’ Selanine muttered under her breath, continuing to toy with the jewel, before snorting a laugh: ‘how the hell can a ring “want” anything...’

‘Is something funny, Miss Aries?’ the lector asked. Selanine looked up from her reverie and noticed that the auditorium was silent, most eyes on her.
‘N-no professorn Berzin,’ she responded quickly, looking flustered. With an indignant nod, he returned to his presentation and Sel lapsed back into her own thoughts.

Sel wouldn’t see Kyera until that evening (she’d manage to wrangle sleeping in the skerpent’s dorm room for the past month, rather than find her own lodgings - still it was an equitable agreement. Kyera shopped, Sel cooked, they both fucked. It worked well.) She couldn’t chase that curvaceous, alluring image from her mind though. Naked and inviting, beckoning Sel to a titillating experience. She could almost smell the skerpent’s sweet, musky scent, the warmth of her soft, fine-scaled hide. Selanine bit her lip. The tightness in her groin was growing again, the ache spreading throughout her body as she continued to fantasize. Sel could feel her nipples, stiff and engorged; so painfully sensitive, straining against her skull-emblazoned t-shirt.
An errant part of her mind pulled the brakes, reminding the equine herm that strong as her sex-drive was, Behavioral Psych 101 had never been this arousing. 

That was when she noticed that the ring was now securely on her right-hand middle finger.

“How...” she wondered quietly, before a wave of arousal blanketed her, erupting from her groin and surging up her spine, drawing a shudder and a small gasp as it over-sensitized her skin momentarily. It was becoming harder to think straight and not undress her classmates in her mind, thinking about bending them over the pews; ramming her long, fat dick into one while another played with her swollen balls. Tit-fucking one while sucking off another... the whole auditorium descending into an glorious orgy.
The searing, unbridled need coalesced just below her navel as Selanine felt her length straining, struggling to swell beyond the confines of her jeans. That singular point, an event-horizon of breathless desire travelled slowly up the length of her trapped shaft, gaining speed as it plunged forward.
Selanine gripped the pew in a white-knuckled grip with one hand as she came, the other flying to her mouth to contain the groan trying to force itself from her throat. Her member throbbed, pumping spurt after spurt of warm, wet spunk into her pants; Her wide hips twitched, trying to buck in the seat. The agony of the moment dragged on - Sel so utterly focused on keeping a low profile that she lost track of the passing moments and seconds.
When it finally ceased, she shakily glanced about. One of the guys was looking at her questioningly; she gave him a quick shrug and a grimace intended to be a grin.
Desperately, she tried to pry the ring from her finger, but the small golden jewel, warm to the touch, wouldn’t budge.
“Fuck,” Sel thought, “I need to find Kyera... now! I can’t stay here...”
‘Professor, I’ve gotta excuse myself,’ Sel announced, getting to her feet. A mutter went through the class as more than a few glanced towards the disturbance. There was a noticeable, dark and very wet stain on Sel’s leg. Move over, as she stood she could feel the moist fabric rub against her dick which was not only still rock-hard (and clearly visible and outlined against her pants leg) but it as though it was actually growing tighter; swelling larger and harder yet. A dim corner of her mind noticed that her shirt seemed tighter as well, but the only thing in Selanine’s mind was finding Kyera. Half of her mind wanted help, the other just wanted to fuck - but with that, she hurried from the auditorium.
