Stretch was somewhere in between awake and asleep when he felt Comic shift on his lap, moving closer to him. Their shared blunt was pressed against his lips, pleasure curling down his spine as he took a long drag from it.
He was feeling good, more relaxed than he'd been in a long time. He loved his brother (and Comic did too), but sometimes he just needed to take a break. He lazily wrapped his arms around Comic’s waist, accepting a few more drags before Comic finished it off.
He didn't know how long they sat there, a comfortable silence filling the room more than words ever could. His hand drifted a little lower, toying with the waistband of Comic’s shorts before slipping under it. His magic had already formed, the bright blue cock twitching a little as he palmed it.
“Hmm, what’re you doing there bud?” Comic muttered, tilting his head back to nip at the underside of Stretch’s jaw.
“Wanna do something fun?” Stretch asked, grinning at him.
While Comic didn't verbally respond, Stretch was pretty sure that leaning and shoving his tongue in his mouth was a go-ahead. He turned Comic around, a hand slipping under his sweater to grab his spine.
He idly stroked it as he freed his cock, enjoying the lustful expression on Comic’s face as he watched him.
Comic moved in closer, a smirk on his lips as he deliberately ground up against him. The friction of their cocks rubbing together was great, and Stretch wanted more. He quickly got Comic’s shorts out of the way, his long fingers easily curling around both of their cocks.
“Aah shit man, you're good at this.” Comic moaned, grabbing a fistful of Stretch’s hoodie to help balance as he rutted against him. He knew he was drooling a little, but he didn't care. It felt good, and Stretch didn't seem to mind.
They didn't really have a set rhythm, but Stretch calmly and deliberately rocked his hips up, half-stroking their cocks. Comic huffed, burying his face in Stretch’s neck. He kissed over his vertebrae, nuzzling him.
Stretch murmured soft praises to him. Despite his fatigue, it didn't take long until they were both worked up.
Comic came first, eyelights briefly flashing into hearts Stretch groaned, the feeling of Sans’ cum pushing him over the edge. He let out a shaky exhale, leaning in and kissing him as he caught his breath.

After some halfhearted attempts to clean up, they fell asleep on the couch, their limbs tangled together.
