I.H.
Lust moaned ecstatically as he caught sight of Horror's dick, letting his swollen folds graze against the tip of the hard cock and drawing a shiver from himself.

Lust sunk himself down on Horror's huge girth with a squishing sound, his mouth parting in a gasp as his wavering eyelights blew even wider. "So b-big.. Mnnh.." He began to ride Horror slowly into the bed.

G.P.
He took a deep breath as he held him. "You're so tight, Ero~" He cooed, panting out happily as the other went down on his massive cock. He wanted to move but he was so sore already, staying still as the other rode him slowly. He brought him into a kiss.

I.H.
The slick sounds of their magic slapping together filled the room as Lust rode Horror into the bed, speeding up the pace gradually. His hazy, blown eyelights were trained on the point where Horror's magic entered into him.

"H-Horror.." He moaned, eyelights flickering inconsistently as he continued to move himself up and down on Horror's pulsing magic. It felt so good.. Like it was curing him, taking away all his pain.

He came around Horror with a muffled cry before he caught his breath and continued on with the pace again.

G.P.
He came too, but not as much as the last two times. His pelvis burned; he needed to find something for his pet. Something to help his behavior for sex.. Shifting, he got an idea, summoning a red cock in his hand. It had a slit in the bottom of it.

"Ero, I have to at least be able to walk the next day, and I'm already sore~ Here~ I'll give you this, so you can help yourself anytime." He murmured, getting up slowly. He shook himself slightly before teleporting away; he had to leave. His phone rang, telling him that another few bodies had dropped in Snowdin forest.

I.H.
Lust shivered against the bedspread, red and purple cum trickling slowly out of his pussy. He sighed, staring at the empty spot where Horror had been before turning to the toy with a dejected huff.

Toys would not help heats.. They may temporarily relieve it, but heats were for breeding; they could not be quenched unless the seed of another was inside him.

Fortunately, he estimated that his heat would end soon, probably the next day. He was already feeling sluggish from the amount of Horror's seed he had taken, a satisfied fuzziness overtaking him.

He sighed, going back to sleep. By next morning, his heat would most likely be gone..

G.P.
Horror finished his work around the Underground by the break of 6 AM. He was dead tired, having a large slab of 'steak' cut out for his pet. He was thinking of cooking it and serving it up for breakfast.

Sugar had returned once more, terrified of his brother being around, but thankful he wasn't sneaking up on him. He found Lust and the smell of filth on him, a red object near him. Sugar didn't understand, walking closer. He nudged the other softly, seeing the bite marks and other scars.

Did his brother like this monster? He paused; well, of course Horror did. It was pretty obvious. He will go make them spaghetti..
