Stretch had never heard of a monster dusting from cumming too many times before, but then he didn’t think it was something that would ever come up in polite conversation.

With the way Blue was pounding him relentlessly against the shower wall, he was starting to seriously consider whether this was going to be the end of him.

He had initially thought nothing of it when Blue had asked him to join him in the shower after he came home from training. It wasn’t one of their usual activities but Blue was filthy from all his hard work. Stretch guessed his brother wanted to have fun, but have all of their mess cleaned away at the same time. It made sense and Stretch was more than up for it- stripping out of his clothing before he’d even got to the bathroom.

The shower started innocently enough, even if Blue was a little more handsy than usual. Stretch took his time in washing the dirt and sweat off his brother’s perfect body, something they both enjoyed immensely if the appreciative groans from Blue were anything to go by. Stretch could spend hours washing Blue’s sculpted form, and he revealed in getting to explore the full ecto-body Blue still has summoned. It was only when the musky smell of spices wasn’t washing away that he started to suspect something was different.

Originally Stretch had attributed the smell to his brother having an impromptu cooking lesson with Alphys. But the smell wasn’t disappearing with everything else. In fact it seemed to be getting stronger, lulling him into a false sense of security. Stretch had done some investigating of his own, running his hands around his brothers perfect ass until he came into contact with his cock. His hard, throbbing cock that was already leaking pre-cum. Stretch had exactly one second to react before Blue flipped their positions and threw him against the shower wall.

Which was how Stretch still found himself an hour later; his long legs shakily wrapped around his brother’s hips as he held onto his shoulders in an effort to stay upright. Blue’s strength was impressive for his stature on a normal day, but his heat-aided fever meant he was able to hold up Stretch with minimal effort. Which meant all his energy was poured into pounding him to within an inch of his life. Stretch’s pussy felt sore and puffy, but the running water soothed his extremities and the pain mixed with pleasure scratched and itch he didn’t know he had. But he had lost count of how many times Blue had made him cum, and his brother showed no signs of wanting to stop. His eyelights were hazy, and his possessive growls were enough to push Stretch to the edge again. But he needed to get Blue to stop, or at least slow down, if he wanted to be able to survive the rest of his brother’s heat.

“please bro- i’m ahh- i’m hhhaaaa” Stretch couldn’t even get his words out, tears falling down his face as his babbled from the overstimulation.

“Paaaapyyy” Blue’s sing song voice cut through the relative silence, as if what he was doing was the most normal thing in the world “You’re Being So So Good, You Can Manage A Little Longer Right?”

“i don’t- oh shit- i dont think i can ahhh”

“Oh?” Blue stopped his thrusts almost completely to push Stretch up against the wall enough to free one of the hands he’d been using as leverage. He immediately brought the hand between them- seeking out the hardened nub at the top of Stretch’s pussy. Blue’s smirk grew wider once he found the sensitive bundle of nerves and began circling it with a feather light touch.

“oh fuck, fuck, fuck! blue please!” Stretch’s tune changed pretty quickly, but the juxtaposition between being fucked so hard and the now silky touches were too much for his brain to comprehend. He could feel his inner walls starting to spasm around Blue, drawing his cock in deeper. But his brother was keeping him on the edge on purpose, the heat bringing out his rarely seen cruel streak.

“Please?” Blue pulled his cock almost all the way out of Stretch before sheathing himself again slowly until he bottomed out. He punctuated his words with a loud moan, as they both began to shake from the effort of keeping upright. “Please What?”

Stretch’s eyes were fixed on Blue’s face as he saw his brother try to hold back from his own climax as well. Blue was panting, moans spilling out of his mouth as he held them both on the edge of a powerful climax. Stretch felt his bones start to shake, in awe of his brother’s restraint even though he was in heat. He didn’t want to hold back any longer, not when he knew how much Blue was going to make them both scream. He wasn’t sure if it was the effects of his brother’s heat, but he needed Blue’s hot cum inside him right now.
