Lightning Skin
The air was abruptly pulled from your lungs as Otto lifted you from his lap and slammed you onto the dark wood of his desk, hands roaming all over your body. Your trousers and pants were deposited onto the floor with a swish of fabric, his head suddenly between your legs, nipping and biting at the now exposed flesh as he fumbled with the fastenings of his trousers.
Gasping as Otto licked a stripe up between your folds, his tongue swirling over your clit with a soft moan, you squirmed on the desk, hands clawing at his auburn hair in ecstasy.
“Hh, O-Otto, fuck,” he grinned up at you, satisfied with the effect his tongue was having, “don’t stop, don’t-”
One hand found your thigh, holding you in place as he pressed a kiss to your swollen clit before his tongue flicked over the sensitive nub, extracting more moans and cries from your tired lungs. Like a man starving, Otto groaned into you as he ran a hand over his cock, struggling slightly with the condom until he was certain it was on safely. His fingers once again dipped into your cunt, scissoring inside you while you bucked and moaned on his desk, conscious that his papers were now strewn carelessly all over the floor. A particularly rough twist had you crying out, begging for his cock inside you while the scientist held you down and pumped his fingers in and out of your aching cunt.
Evidently proud of his work, Otto loomed over you with a smile, his thumb still circling your clit gently.
“You look so beautiful like this, darling,” he shifted so that he was positioned at your entrance, “so eager for my touch, yakiri, you are perfect.”
Propping yourself up on your elbows, you tangled your hands into his hair and pressed a kiss to his lips.
“You still talk too much,” you kissed a line down to his neck, marking him just like he had bitten bruises all over your body, “sir.” He smiled at that.
Arching his back slightly, he rested his forehead against your own, his curly hair brushing over your face.
“Darling,” he whispered, “do you still want this, do you want me?”
His eyes were so soft, almost begging, and you wished you could hold this image in your head forever.
“Of course, Otto, I want you.”
Hands gentle on your hips, your professor slid into you with a moan, the soft burn of being stretched open made you whine and grip at his arms, back arching as your head fell back onto the desk. He was big - huge - and you were only just prepared for how full you felt. He wasn’t even fully inside you yet, and you were already gasping for air, fingers digging into his forearms in ecstasy.
“Are-are you ok?” he huffed, stilling inside you.
Barely able to form coherent sentences, you managed a muffled “yes” and then let out a strangled cry as he bottomed out and then stalled, taking a moment for the both of you to get accustomed to the new sensation of being utterly interlocked.
Taking a moment to survey the sight beneath him, Otto lifted your hips so your legs were wrapped around him, every slight movement extracting gasps from your aching lungs.
“Sh-shit! Otto, fuck, I-” you trailed off as he grinned down at you, his hands ghosting over your own, pulling your arms over your head to pin you down on the desk, his body holding you in place.
“Yes, yakiri?” There was a new, sinister edge to his voice, to the way he loomed over your prone figure, an element of darkness in the raw power he now held over you.
You groaned as he shifted again, rolling his hips against your pelvis, testing the waters.
“I-uh, I…” speechless, you gazed up at your professor, who seemed like a man transformed from the sweet man who had let you off being late a mere few hours ago.
“That’s what I thought, darling.”
With a creak of wood, he began slowly, earnestly, to fuck you. You felt as if you were on fire, your body so tuned into his own, nerves alight with white hot fire everywhere his skin touched yours. His lips were lightning on your neck, one hand pinning your wrists to the desk, the other clutching at your thigh with desperate abandon and a strength you didn’t know he possessed. The noises leaving his mouth were heavenly, the panting and groaning as you clenched your legs around his waist made your lungs constrict at the effect you were having on this man.
But you couldn’t focus on anything for too long, as Otto’s mouth began to trace down your body to your chest, a cruel smile traced on his face as he bit your nipple gently, soothing it with his tongue swiping over your skin. At the same time, his free hand slipped between your bodies to apply extra pressure to your clit, sending sparks of delicious pleasure spiralling up your spine.
“Otto!” there was no escape from the feelings rippling through your body, and you could feel that coil of heat in your belly fast approaching its climax, “F-fuck, sir, I’m close - I, professor!”
“That’s it, darling, let me hear you,” he growled, teeth ivory against the soft flesh of your breast, “come for me, (Y/N), you feel so fucking good, come for me.”
The strain in his voice was evidence of how close he was too, neither of you able to last long with all the foreplay, and the burning in your navel made it clear that you were going to break first.
“Please, please don’t stop,” you gasped, “Otto, sir, I’m so close, I -”
The stretching burn of being filled by your professor, his hand so gentle between your legs, mouth soft on your breast, his panting moans and the way he shuddered against your body - it was incredible. With an almost animalistic cry of ecstasy, you gave yourself over to the fire in your stomach and came harder than you ever had before, muscles aching in pleasure with the effort.
It was all too much, and you shook free of his grip. Sitting up on the desk, legs hooked around him, you buried your face in his chest as he continued to fuck you, paying no heed to the overstimulation. Otto groaned, his head sinking to rest on your shoulder as you came around his cock, picking up the pace, chasing his own high as rapturous spasms rippled into his body.
“Mhf, fuck, yakiri, so good..” he trailed off, lost in your body.
“Sir?”
“Yes, darling.”
“May I, um, can I -” you swallowed, “can I ride you?”
Surprise etched into his face, he looked at you, “Of course, (Y/N).” he smiled. “But I’m not sure how long I can last..”
“I don’t care, sir, it doesn’t matter.”
With a grin, he lifted you from the desk and sunk into his chair, the sudden change of position making you both groan in pleasure, Otto now much deeper inside you. Tentatively, you rolled your hips, extracting a moan from the older man, along with a nod for you to continue. Resting your hands on his shoulders, you positioned your knees at either side of his thighs and began to slide up and down his length, the motion making the chair creak slightly beneath your combined weight. Eyes fluttering closed in pleasure, Otto gritted his teeth and gripped your waist tightly, trying to maintain his composure as you bounced yourself on his cock.
His head fell forward into your chest, and you trailed one hand through his hair, pulling slightly to be rewarded with a gasp of pain, his nails digging into your sides, pulling you closer to him.
“Yakiri…” he moaned, “don’t stop..”
Pulling his head back, you kissed him, teeth tugging at his lower lip, emboldened by the effect you were having on him. As if to remind you who was in control, his hand crept up to your neck, squeezing slightly as he deepened the kiss and thrust up into you.
Wrapping his free arm around your waist, Otto groaned into your mouth as he felt his climax approaching, unable to control himself with you on his lap. A particularly rough thrust made you moan in sudden pleasure, the familiar heat pooling in your belly once more as your professor pulled you even closer to him, skin afire where your bodies met.
“Otto, I think -” he kissed you once more, “I’m gonna come a-again.”
“I’m close too, darling,” you could feel him shuddering beneath you, “you just feel so damn good, I-I can’t -”
You silenced him with another kiss, focusing all your efforts on the man beneath you, increasing the pace until you were both gasping for air.
“F-fuck-”
“Otto-”
Unable to take the constant pressure on your clit, and the incomparable feeling of being entirely filled by Otto’s cock, you came with a shout, arching your back and forcing yourself even lower onto his cock, going limp on his lap.
“Yes, fuck, (Y/N), so fucking good -”
With an unholy noise of pleasure, Otto thrust up into you one last time as he came, his cock twitching when he finally stilled inside you, panting with effort.
For a moment, the two of you just sat there, stunned.
“Otto?”
“Yes, darling?”
“That.. was amazing.”
“I’m so glad, yakiri, you did so well.”
