When Regulus woke up he was tucked into the bed rather than hanging off of the side and Remus was nowhere to be found. He saw a letter on the pillow next to him, it read:

Dear Regulus,
I had to hurry back so that Sirius and the others wouldn't get suspicious. I'll meet you in the shack again tonight at the same time so we can talk rather than just doing it. I really like you and want to make this work. See you soon. Love you lots from Remus.

Regulus went back to read the line 'love you lots' again, it made his heart flutter and he felt happy. He moved so he was lying on his back with his limbs spread out around him so he could take up as much space as possible. After a couple of minutes of lying peacefully he felt the covers move slightly at the bottom, he looked down to see someone under them with him, they'd climbed up from the foot of the bed. He felt warm hands slide under him so they were caressing his bottom while a soft tong licked the nib of his penis repeatedly and made it erect. He wondered why Remus was back there already, it wasn't the time they were supposed to be meeting. But Regulus was happy all the same; happy that he was spending more time with the boy he loved. It was different this time, instead of being fast from the beginning it was slow and steady, building up in speed. He held onto the bed and let whimpers of pleasure escape his lips. The tong didn't wrap around this time, it licked up and down in time with the movement of the head. He also got there a lot faster. He was unable to speak and warn Remus like he did before so he just came.

The mouth let go, Regulus climbed under the dark sheets with him. He couldn't see anything so he had to feel his way down Remus's body. He slid down underneath him until he found Remus's crotch. Once again he already had a throbbing erection because the head he had just given Regulus had turned him on. Remus was already naked so Regulus decided to give Remus what he'd just gotten. He slid his mouth over it and began moving back and forth, he could hear Remus trying not to make much noise but he still let out little whimpers now and then. He wrapped his hands around Remus's waist so he could steady himself. Remus came and with almost no time to think Remus dragged him up so he could see a slight black outline of Remus's head looking down at him. Remus grabbed Regulus's legs and threw them upwards. He slid under and penetrated Regulus once again. With his hands on Regulus's waist he held on tight so he could move Regulus back and forth. This time Remus hadn't said a word and neither had Regulus. Regulus felt strange, wondering if he'd upset Remus and that's why he wasn't saying anything apart from the grunts and moans as he came so close to climax. Regulus held onto the bed and moved himself in a way he thought would make Remus happy, he made the movements long and slow to prolong the moment, Remus was groaning with pleasure even more. Suddenly Regulus decided to move fast, Remus came for the second time and they both sat there trying to catch their breath.

Remus finally removed himself and lay down so that he was hugging Regulus tightly. Regulus returned their embrace and was surprised by how thin Remus was, he was sure he remembered Remus being rather muscular before. He took his head out of Remus's chest and went to kiss him. They were both hot and sweaty so the hug became slightly uncomfortable. A bit of hair fell in Regulus's face, it wasn't his hair. It was very long and greasy. Regulus knew something wasn't right so he pulled his arms free of the hug and pulled away the covers so he could see Remus.

The person holding him, the person kissing him, the person he was lying naked with, the person who he had just had sex with was not Remus.

"SEVERUS!" Regulus screamed at the top of his lungs, the shock was unbearable. Tears began falling down his cheeks; he buried his head in his pillow and mumbled some nonsense.

"What's wrong?" Severus asked the now crying Regulus. Regulus froze and slowly lifted his head out of the pillow.

"What's wrong? What's wrong?" he sounded calm but there was obvious rage in his watering eyes "what's wrong is the fact that i just slept with you thinking that you were Remus! This means that I've cheated on him! So we're gonna have to break up! It's all your fault!" Regulus climbed on top of Severus and pathetically hit him repeatedly, his strength gone from all of the crying. In the end he just gave up and lay down on Severus with his head buried into Severus's chest where he cried even more. "Why did you do that anyway?" his voice was quiet and he didn't look at Severus when he spoke. "Did you know it was me?"

"I knew it was you but I didn't know about you and Remus and I thought you knew it was me and that's why you joined in rather than pushing me away" Severus's eye's watered slightly too but he didn't cry properly, it was just a couple tears that rolled down his face. He tried to keep it together for Regulus so that he could be the upset one. "I'm sorry"

"I'm sorry" they both lay there, crying and apologising.
