"Hey." Nick turned and smiled at Greg out he walked out of the bedroom. Greg had the tendency to bear a resemblance to a little kid, especially in the morning. His hair, last cut unevenly by Greg himself, was plastered flat in some places but sticking straight up in others. His tan face was flushed with tints of red and when he tried to stop his yawn, his brown eyes squinted shut in concentration. It made him look incredibly adorable. Then Greg stretched his arms over his head, causing his t-shirt to ride up.

"Aren't you cold with just a t-shirt?" Nick asked curiously. Their air conditioner had been on full blast for the past few days and their townhouse was practically a freezer.

Greg's arms came back down to his side to find Nick's arms coming from behind him to wrap around his waist.

"A bit, I was going to grab a sweatshirt." Greg smiled and leaned into Nick's embrace.

"You mean my sweatshirt?" Nick teased, a smirk playing on his lips. With their house an icebox, Greg had taken to wearing Nick's A&M sweatshirt.

Greg tried ignoring his rising blush by responding "You let me wear it. In fact, you insisted I wear it. Especially when I'm around that guy subbing for Cath this week."

"I like when you wear my college sweatshirt. I think it's cute. And I need to mark my territory." Nick turned Greg around so they were facing each other.

"Mark your territory?" Greg grinned and leaned in to kiss Nick.

"You heard me, that guy's been eyeing you. He also asked Sara if you were seeing anyone." Nick pulled away from the kiss to breathe in Greg's scent.

"She told me." Greg smirked. He kissed Nick again. "She told him that I had an incredibly jealous boyfriend."

Nick kept a hold onto Greg as he moved them both over to sit on the couch.

"Well, your boyfriend is incredibly jealous." Nick absentmindedly spiking Greg's matted down hair.

"Well, if I could wear your sweatshirt in this heat I would." Greg gestured to thermostat on the wall which noted the outside temperature as 104 degrees. "Sadly, that's not humanly possible."

"Mmm, don't worry. I have an A&M t-shirt." Nick murmured.
