(Yet again: WHY IS THERE SO LITTLE PICTURES?! Anyway I got an idea, I saw a lot of people doing something like: Cross loses a bet and has to wear a dress. And then I thought why not switch roles a little and have someone lose a bet to Cross? [Don't worry he's still a button] So here we are! Also a little heads up this is the first time I'm writing a threesome so it might not be good. This is lime.)

Killer's POV:

'I can't believe I agreed to that bet.' I thought as I tried to figure out how the fuck do I put on this dress.

'Ughh this is so humiliating.' I finally got the dress on me.

''Don't forget to summon your body Killer!'' I hear Cross yell through the door.
''There is no way in hell I'm doing that!'' I shout back.
''Come on Killer Cross won fair and square you have to. Just get it over with.'' Nightmare said. Wait he already changed?

You're probably confused. Okay let me explain. Me and my boyfriends had a bet and whoever lost had to wear a dress with full body summoned. What did we bet on? Doesn't matter, what matters is that me and Nightmare lost. And now we have to do it.

With a heavy sigh I summon my female ecto body and get out of the room I was changing in, to the living room. I was meeted with Nightmare wearing his dress and Cross squealing on how good he looked.

''We look ridiculous.'' I said as Cross started to squeal at me to.
''Bitch, speak for yourself I look fabulous.'' Nightmare said flipping his nonexistent hair.
''YOU BOTH LOOK SUPER CUTE!'' Cross shouted.
''Not as cute as you.~'' Nightmare and I said in union. Which made Cross blush.

Me and Nightmare made an eye contact kinda speaking without words soon coming to agreement. We both smirked as we started to make our way towards Cross.

''Hey Cross, you know what?~'' I started as I lifted his chin to look at me.
''W-what?'' he asked his face purple.
''We both agree that you always look very cute but~...'' Nightmare said hugging Cross from behind.
''We're not sure when would you look the cutest.~'' I finished hugging Cross in a way that his face was in my breasts.

''Completely flustered like right now or~...'' Nightmare started licking Cross' neck after he said that.
''Or moaning mess under us.~'' I finished as I rub his spine. Cross was already moaning and having a hard time putting words together but he finally managed to say something.

''I g-guess you'll ahh have t-to find ohh out.'' He said through the moans.
''Gladly'' we both smirked as we said that.
''Though I suggest we take it somewhere more private.~'' Nightmare purred.
''Couldn't agree more.'' I said and we teleported to Nightmare's bedroom. 'Cross won't be able to walk for a week after this.'

(Idk if it's good or not. But I hope you enjoyed. Bye~)
