You Mistake The Brothers: Grayson

You've been dating Grayson for about a week now and haven't met his family. You admit it, you're a little nervous, but you're not gonna let your shyness get the best of you. It's the night of the dinner at Grayson's and you doll yourself up in a new semi formal dress, curl your hair, and do your makeup. Grayson comes to pick you up at around 6. When you get to his house, he introduces you to his mom, dad, and older sister, Cameron.
"Ethan's upstairs. Probably sleeping. I'll go fix my hair and get him down here." You nod and sit down at the kitchen island with Cameron while their parents made dinner. Your phone buzzes and you glance to see a text from Grayson.
Gray: ask where the bathroom is
You wonder why but put two and two together and contain a small smile.
"Uh where's the restroom?" You ask.
"Down the hall, third door on the right." Cameron said with a smile. You nod and head down the dark hallway into the bathroom you take a deep breath and place your hand on the doorknob. Quickly, the door opens and you catch a glimpse of him before the bathroom light (and only light in the entire hall) turns off and you're both standing in complete darkness. From the little you saw, he really did fix his hair. It looked completely different as matter of fact. Kinda messy but sexy. You make the first move and go for it. His lips feel different. Plumper. He doesn't move his and it's awkward. You pull back.
"Something wrong?" You ask feeling cautious like you messed up.
"Uh, nice to meet you too?" His voice. It was deeper. It was...NOT GRAYSON!
"Oh. My. Gosh." You whisper yell.
"I'm so-I didn't-I thought-" you try hard to explain yourself but the words don't fit together.
"It's fine. I won't tell if you don't." He said. I face-palmed myself and he walked down the hallway towards the kitchen. I stood for a second hating myself and walked back out into the kitchen. Everyone was sitting around the kitchen island including Grayson. I looked at him and smiled awkwardly and he gave me a look as if saying, "Where did you go?" I shrugged and glanced at Ethan who was on his phone scrolling through Instagram. 
After dinner, you, the twins, and Cameron go down to the basement for a movie and Grayson pulls you aside. 
"Ethan told me-"
"I'm so sorry-I-I didn't know." You quickly try to explain yourself and feel your cheeks get hot.
"Y/N, it's ok. I know you didn't mean it. It's not the first time." You exhale relieved he wasn't mad. 
"Just don't let it happen again." he chuckled and winked.
