"Don't worry no one will be up here for a few hours."

"Are you sure about this?"

"Positive. Harry and Ron are out with Hermione and Neville said he was going to study in the library. He'll be there for hours."

"Oh, alright then," said Dean Thomas, "Just a quickie though."

"Alright fine," Seamus Finnegan said as he started to remove his clothes.

Dean gave one more tentative glance toward the door before he began to remove his clothes as well.

Once both boys were fully naked, they took their familiar positions; Dean was leaning over the side of the bed and Seamus was standing behind him. Seamus took the lube from the bedside table and began applying it on himself.

"Will you hurry up? I want to get this done before someone comes back," Dean said impatiently.

"Alright, fine." Seamus put the bottle down and grabbed Dean's hips.

Dean braced himself for Seamus's hard cock, grimacing in pain as he felt the head push past the tight ring of muscles in his arse. He bit his bottom lip to stop him crying out from the initial pain. Dean gasped in pain and gritted his teeth. He was eventually able to breathe out the words, "Did you even put lube on?"

"You said to hurry," he said with a small smirk, which quickly disappeared as Dean shoved himself back, taking Seamus to the hilt.

Once they had both relaxed, Seamus began to pound into the other boy's rear. His thrusts became faster and harder. Dean responded by shoving himself back onto Seamus's cock. This extra force drove Seamus deeper into Dean, causing him to hit his prostate with each thrust. This impact sent shivers up and down Dean's spine.

"Mmm, fuck yeah, Seamus!" Dean called out, his voice quivering with pleasure.

Seamus moved his hand from Dean's hip to his cock, stroking in time with his thrusts.

Dean exploded from the sensation. His come spilled all over Seamus' hand and the bed. Seamus gave one more thrust before he, too, came.

Seamus collapsed on top of Dean. The boys stayed in that position panting for a few minutes before Dean, having the air being forced out of his lungs and losing circulation, spoke, "Do you mind moving your fat arse?"

Seamus flashed him a pout. "It's not that fat," he said in indignation. He forced himself off of Dean before adding a hesitant, "is it?"

Dean rolled his eyes before they both picked up their wands and cast a cleaning charm on themselves and their area of crime. After a quick inspection the boys dressed themselves.

They both looked up as they heard the door open. Neville entered the room carrying a large load of books. He looked surprised when he noticed that he was not alone in the room, "What have you two been doing? You both look flushed."

Seamus and Dean looked at each other and let out a nervous laugh.

Neville also let out a nervous laugh, "Seamus –erm– would you mind if I tested this plant on you?"

"What is it?" Seamus said as he looked at the slimy green plant Neville pulled out of his pocket.

"It's Lipusweed. It's thought to aid in weight loss," he replied rather sheepishly. Dean let out a stifled laugh.

"My arse isn't that fat!"
