[ A, S, F] Clary x Jace x Simon What If The Threesome Actually Happen

Not Proofread

Based on the Mortal Instruments: City of Bones the movie. This is the alternative version of what happened when Simon found Jace and Clary outside of Clary's room together. Was Jace joking about having a threesome?

Clary and Jace was casually making out in front of Clary bedroom after giving her, her birthday gift. When Simon suddenly open Clary's bedroom door and seeing Clary and Jace stand too close to each other.

"Simon, I thought you were..." Clary started

"Asleep"? finished Simon

"Yes, I was." replied Simon

"Um, we were just" Clary said

"Next time, it might be a nice idea to mention that you already have a man in your bed, so we can avoid such uncomfortable situations." said Jace

"You invited him to bed" shout Simon

"I know, it's ridiculous. We would never have all fit," replied Jace

"I didn't invite him into bed. We were just kissing." finished Clary

"But on the topic this threesome are you like joking or are you foreal legit about doing it?" asked  Simon

Clary and Jace looked at Simon like he has grown two heads.

"Simon are you even being serious right now, like are you really trying to have a threesome while my mother is still missing and you are healing from your injury as well." said Clary

"Are you in the right head space to make that of decision" continues Clary.

"I'm very serious right now Clary, I was literally kidnapped by vampires and if this the life that I'm going to live at least let me now die a virgin." Said Simon

" Okay, since you are so serious I'm down to do this threesome for the little virgin nerd to die happy". Jace replied

"You guys are serious both crazy right now but whatever let get this over with and let not speak about this after this is done". Finished Clary

Inside Clary bedroom

All three them were sitting on Clary bed awkward waiting for someone to make the first move in this this threesome. If felt like forever waiting so Clary took the initiative to make the first move since the guys wanted to have this threesome so bad but don't have the balls to start it.

Clary stand up from the bed and pull her shirt over her head before climbing back into the bed kissing Jace right on the lips. Simon and Jace sit on the bed looking shocked at what Clary was doing but started to get hard in their pants.

Jace was shocked at first when Clary kiss him but after a second he took over and try to win dominance over Clary and slip his tongue down Clary throat. After a while Clary pull away from Jace and move over to her best friend Simon and starting kissing him at the same time removing his glasses and shirt from his body going down and kissing on the neck leaving hickey.

While kissing Simon, Clary felt Jace kissing her neck and back making her feel very hot. Pulling back from Simon she lay back on the bed and just let both Simon and Jace took over.

Jace stand up from the bed and removing all of his clothes from body and climbing on the bed on top of Clary kissing all over her body from head to toe. Undoing Clary pants and pulling them down and kissing back up to her neck.

Simon also removed his clothes as well and went to kiss Clary on the lips and have another heat make out session. Things between the three got heat very fast the only thing that you can heard in he room is heavy breathing and skin slapping against each other.

Once everything was over the three of them laying on the bed laugh about what just happen between the three of them. They all think this was a very fun experience to try and maybe they will think about doing this again maybe in the future.

The end
