The special guest is muzan because he's hawt (THREEWAY WITH ONE OF THE OTHER UPPERMOONS BEING A PEEKING TOM BTW LOLLLL)
Muzan just stood in the doorway and looked you both up and down, he looked kind of intrigued and the point was proven by a few simple words "whatever you two are doing I'd like to see more so do carry on".
Muzan watched as you pretended he wasn't there, Douma shoved his cock back into you, making you moan his name. The wet and sloppy sounds that came from the skin to skin contact were echoey as you felt another release coming, you'd let him know you were cumming again and he stopped.
Douma was going to overstimulate you by controlling when and where you cummed, when you remembered Muzan was still standing there you coaxed him over giving him a look of envious deprivation.
He could tell what you wanted and so he walked over to the bed and gave Douma a stare (😶) and so that was it.
Muzan moved to a comfortable position so that Douma could fuck your pussy and muzan had you sitting on his cock, muzan started the first blow and began moving at a slow and steady(wins the race kinda thing)pace, while Douma eased himself into your wet sloppy cunt.
Muzan was starting to get rougher and Douma got the jigg and so he got faster, your eyes rolled to the back of your head from the stimulation of two cocks filling you up, no less that of your superior's.(I'm 12 btw guys 😶/j I'm actually 13 lul)
Tongue lolling out to the side your senses faded away as muzan reached infront and played with your clit rubbing circles to edge you closer just so he could overstimulate you.
Douma thrust into your pussy as the wet sloppy sounds of your bodies came together in a beautiful symphony, as soon as you came your senses were messed up and so both the demon king and upper ranked demons thrusts became sloppy and they released their hot load inside of your dripping holes.
They pulled out and gave you a rest "we're not done yet you slick slut"muzan seethed into your ear as he gave you a small peck on the cheek.
"Oh dear it seems we have a peeping tom hmm?" Douma lolled out the words in a hazey tone.
As Douma walked past the door frame, you finally got a clear shot of who was watching.
AKAZA?!
waking up in Douma-san's bed you got up, drunk from the other night you fell flat on your face weak kneed. Needless to say you would never ask Douma, Akaza and Muzan to shove their cocks in you both together ever again.
You could have sworn they made you cum atleast 13 times while them on the other hand probably only 5 which was believed to cease since they were demons and you a mere slave for their kind.
