"We use the light system. Green is go, yellow means give me a minute and red is a hard stop. Safeword is pineapples and us, Sapnap and I are sir or daddy, not Quackity or Sapnap. Got it?" Quackity explained, eyes flicking between Sapnap and Karl.
"Yes sir."
Sapnap pulled out a smaller length of rope as he began to secure the blonde's wrists together too.
"Too tight?" Karl shook his head. "No, I'm ok, sir." Sapnap smiled at that and kissed his forehead.
"Good boy, let me know if that changes ok?" The submissive nodded, slipping into the very familiar headspace that he loved. "Yes sir"
Quackity picked up the abandoned Monster can that Karl had dropped, still covered in lube as he moved how to press it to Karl's hole.
"Ready?" Karl nodded and breathed out softly, "Yeah. Go for it." Quackity began slowly pushing in the lubed up Monster can and the response was instantaneous.
Karl began squirming immediately, his back arching as he felt himself being stretched so impossibly wide all the while the metal and lube were both cold, quickly being warmed up the further he pushed in.
"Sir, take it out, it's too much!" Karl begged, his eyes filling with tears as he tugged at the ropes roughly, honestly impressed at how good Sapnap was at tying proper knots.
"Colour?" The response was instant. "Green." So Quackity kept pushing. The tears in Karl's eyes fell as he felt the begs for Quackity to stop tearing from his throat.
"Look at you puppy, crying like a little bitch in heat because of a can. What? You can't take it? Too bad, color out or Quackity's gonna fucking break you."
Karl's eyes rolled back at the words, nodding quickly.
"Green sir, fuck, I'm so green" he gasped, his back arching as the can pressed into his prostate, rubbing the bundle of nerves in between his walls and the can. Daring to make eye contact with either of the two.
The brunette chuckled, pulling the can out slowly before he pushed it back in. "Fucking slut. Now be a good puppy and keep making those pretty noises for us." Quackity said as he continued slowly fucking him.
"I couldn't, ah fuck, I couldn't stop thinking about it," Karl whimpered, "When you said it the other day. Needed to be full."
Karl let his head drop backwards, a groan escaping his lips.
"Yeah? How full are you now then, baby?"
The brunette punctuated his words with a hard thrust, hitting the blonde's prostate dead on. The blonde couldn't speak and he could barely breathe.
