Obviously Stiles is not a needy boyfriend. He's not possessive, he's not demanding, and he's not needy. But there are just some little decisions in life that Derek just can't make on his own. It's just courtesy that he ask for Stiles' opinion. Because they are partners now. They live together, they eat together, they sleep together. So when Derek goes and does this behind Stiles' back... Stiles just...

"What the fuck happened to your FACE?!" he says soon as he comes home from work and finds Derek cooking in nothing but a towel. At first he's distracted by the still damp chest hair and the towel being held up by an erection but when he reaches Derek's face he can't even hold himself together. What would drive Derek to act out such a horrendous sin?

"What?" Derek's smile slowly disappears as he looks at Stiles in concern.

"Derek, you literally just gave me a heart attack, and I don't know how to react."

Derek leaves his place by the stove and walks up, arms going awkwardly limp as if they're so used to wrapping themselves around Stiles that they don't know what to do in that moment. "Can I get a kiss first and then we can fight about whatever it is you wanna fight about?"

"Heck no! Not with a face like that. Honestly, Derek, why would you do this to me? I thought you loved me." Stiles huffs a fake cry and stomps his way out of the kitchen and into their bedroom, diving head first into their bed like a kid.

"Okay then, I guess I'll just put some clothes on."

"No wait," Stiles reaches out but Derek dodges him as he walks by, heading to their closet. Stiles watches intently as Derek let's the towel fall to the floor and flexes his ass cheeks a couple of times while looking for something to wear. Stiles can't have that, so he rolls onto his back and strips out of his shirt and pants. He's naked - he was going commando because they're on somewhat of a year round honeymoon so they're having sex like all the time and he just can't be bothered with the hassle that is underwear - and sprawled out across their bed when he calls out, "Deeeereeeeeek!"

"Hmmm?"

"C'mere and sex me up, you clean shaven beast, you!"

Derek laughs as he jumps onto bed and hovers over Stiles, waiting for him to make the next move.

Stiles dares to look at the offence that is his face. "Gah! It looks like a naked bear!"

Derek pretends to look offended, "It looks nice!"

"Oh god, what... I can't even..." Stiles hesitantly brings his hand up to Derek's face, testing the waters. Derek leans in to it before Stiles can back out and- Derek shaved his face, and this is real life, and okay, what the fuck? He sighs and grabs at his hand with his other free one, theatrically crying, "It burns!"

"Shut up. It's not like I haven't shaved before."

"No! you always just trim your beard and make it look nice and sexy. You never get rid of it!"

"Relax, it'll grow back."

"Okay, I guess we're breaking up until it does then." Stiles knows he's being a drama queen, but he also knows the more he puts up a fight, the harder Derek will fuck him later. He tries to squirm away but before he can make it two inches away, Derek pushes against his chest and pins him to the bed. Now that Stiles is looking, he notices that the absence of the beard makes way for more intense expressions on Derek's face. Was he always this animated?

"No, we're not." Derek's voice is doing that growl-y thing again and Stiles can so dig this.
