Last time

Weary, Sans leans on Red's shoulder. Smiling gently down on the smaller skeleton, Red quickly scoops Sans up and takes Sans to his room. Placing Sans in the bed, Red leaves the room for his own, glancing at the sleeping skeleton whom he has fallen for after so long of being lonely and without true companionship. "Goodnight my love" He mutters as he closes the door.

And now

With Sans

Sans lay in the bed, woken by a fuzzy itchy warmth that spread through his bones. Groaning, he fidgeted in the soft blankets of the large bed, trying to ease the itching now burn. "W-what's going on? Why do I feel like I'm burning from the inside out?" He groans, soul pulsing a bright blue light.

Hearing the sound of the door opening, Sans rolls over to see Red at the doorway. Somehow seeing the other being made his soul flutter and the burn to settle some. "Sans? I heard a noise in here and went to check on you. But I think I know what's wrong." He starts, making his way to the bed where Sans lay.

"Wha-what's going on Red? Why do I feel so like my bones are on fire?" Sans wines desperately, leaning into the others touch as Red caresses Sans' skull. "You're in heat, Sans." Red explains as Sans' eye lights shimmer in recognition of the term and its implications.

"W-what?" The smaller skeleton groans out. Nodding, Red collects the small skeleton into his arms as he sits down on the bed.

The two clack their teeth together in sort of a boney kiss, magic tongues of red and blue sliding around each other in an intricate dance. Their ecto-tounges intertwine as the kiss gets more heated and Red starts to get handstand. Sans moans as the Red caresses his shoulders down to his ribs, getting in between the bones and crevices.

Red takes his time caressing Sans, slowly making his way across Sans' chest through the dress the other hadn't changed out of yet.

" Red please, more" he begs, trying to wiggle out of the dress. Chuckling deeply, Red complies, all but ripping the dress off of his much smaller companion.

Making his way down Sans' ribs, Red slowly makes his way to Sans' pubic arch. Laying the smaller skeleton on his back, Red uses his younger to lick a solid strip up Sans' pubic inlet.

Sans arches up and moans lewdly at the attention, magic beginning to collect in his pelvis more, creating a blue glow to his bones. At this point there's a tell-tale red glow from Red's nightclothes.

Glancing down, Sans sees this and tries to sit up. Managing to do so enough to touch it, Sans' phalanges brush the clothed bulge. Red groans loudly as Sans' somehow skilled hands caress the bulge of his magical erection straining his pants.

'Oh boy if he keeps this up I'll blow before I can get it out of my pants. This can't be his first time' Red thinks to himself as he lifts Sans back into his lap, right in front of the huge erection straining the larger's red pajama pants.

At this point, Sans is lost to his first heat. Panting, Sans reaches for it and pulls at the waistband of the pajama pants. Complying to what his mate to be wants, Red pulls off his pants, leaving the both of them naked.

"Sans, are you ok with this?" Red asks cautiously, not wanting to hurt the other. Receiving an eager nod, Red proceeds to caress Sans' pubic arch. Sans lurches forward, the top of his pelvis brushing Red's ecto-genitalia.

Red groans as the contact sends sparks up his spine. A blue glowing ecto-vagina formed in a low popping noise, dripping obscenely with ecto-juices. Red has to stop himself from wreaking Sans immediately, remembering it's the patters first time at this.

"I have to prepare you first, ok?" Red asks, waiting until he got a sign of confirmation before taking his middle claw. Coating it in magic to avoid hurting him, Red slowly teases the outer labia and clitoris.

Sans' breathing goes more erratic if possible. "Nnng R-red. Please it burns." Sans groaned out after a minute of the slow teasing torture he was no doubt feeling at the slow pace.

Taking the hint, Red slowly inserts the first digit into the glowing magic cunny. Pausing to let Sans get used to the intrusion, Red slowly pumps his finger in and out; adding a finger as the conjured walls relax once they get used to the intrusions.

Sans moans breathlessly as each digit is added. Laying Sans down on his back so as to have more access, Red increases the tempo at which he pumps his phalanges into the writhing skeleton below him.

"R-red..." Sans manages through his gasping moans of ecstasy. "Red please, enough. Please s-stop t-teasing." He breathlessly stutters high pitched through keening moans.

It takes all Red has not to start pounding relentlessly into the right heat surrounding his magic-coated phalanges. "Are you absolutely sure Sans? I'm not exactly small." Red asks again. "F-for fucks sake Red just fuck me already!" Sans all-but-shouts, his left eye glowing blue fiercely with the intensity of his demand.

His left eye glowing faintly in response, Red removed his phalanges from the right heat they were buried in. Sans low keen from the loss is immediately interrupted by a loud moan as Red quickly replaces them with the head of his large erection.

Slowly trying to ease himself into the other, Red groans at the tightness of Sans' labia. He continues on slowly when, in a sudden show of strength, Sans flips the two of them over so that Red is laying and Sans is hovering on the end of his ecto-member.

"You were.....taking too.....long" Sans gasps as he holds himself on the end of Reds girth. Before Red can protest about not getting hurt, Sans slams himself down on the erection, almost screaming as he moaned loudly walls clenching almost painfully around Red's bright red member.

"Sans. This is why I was going slow." Red tried to admonish, but ultimately fails as he growls when Sans rocks himself on his member. "Fine. You want it rough, you got it rough." Red grits out before slamming the other back on the bed then ramming into him at top speed.

Sans reacts immediately, moaning loudly as he orgasms hard for the first time of the night. Blue ecto-release seeping out between Red's member and the lips of Sans' ecto-vagina. Grabbing Sans' legs and placing them over Red's hips, he thrusts ever deeper into his cunny, the walls gripping him as harsh as his thrusts.

It doesn't take long for Sans to come again, coating Red's member in his blue release, his walls squeezing Red's erection. Red pounds into the other through his own orgasm, hips stuttering as the blue walls clench his member in oversensitivity.

Taking one of Sans' legs and pulling it flush with his chest, Red pulls out and rolls Sans onto his side. Laying on his own side behind Sans, Red re-inserts himself in the quivering, dripping, over sensitive cunny with a low groan. Sans keening loudly as his oversensitive sex is stretched yet again by the large member. Sans has been beyond words for a while, only managing low keens and breathy moans as the pleasure overwhelms him.

Neither last long in this position. Orgasming at the same time, they change position again where Sans is leaning forward with his obscenely dripping ecto-pussy in the air while his front is pushed into the mattress. Gripping Sans' hip bones, Red sets a brutal pace.

Reaching around with one hand to rub Sans' clitoris, Red rams hard and deep into the conjured sex. Sans spasms as he comes from the stimulation, tightening tighter than ever. Groaning at the increased tightness, Red feels his own release approaching again.

Hips pumping erratically as he continues to rub at the nub or nerves, Red releases inside Sans making the other reach another intense orgasm.

Pulling out, Red catches his breath as Sans' even breathing signifies that he had passed out from all the exertion. As Red calms down from the pseudo-heat that Sans' triggered, he feels incredible guilt weigh down on him.

'Oh god what have I done? He'll never forgive me.' Red panics as he thinks of a way to fix it. Thinking quickly, Red casts a spell to make the whole ordeal seem like a vague dream. Sneaking out he makes it to his room and dozes off just as the sun rises in the sky.

Meanwhile Sans sleeps away, deep in sleep and unaware of everything around him.
