"Is that why you made love to him in front of me?"
"Nobody forced you to watch, Sebastian." She said.
"That's right. Who's the peeping tom now?" Alex said.
Sebastian went silent. He wasn't exactly proud of the moments he had spent watching them.
"What is he talking about, Alex?"
He ignored her. "Feels pretty bad, huh? Doesn't it? Well I owed you that one little brother. You spent a whole month lying to me and even worse, lying to Melanie. Then you impersonated me while you fucked her and I had to watch you do it. That was just payback. Now get out of here. Melanie has made her decision and we will expect you to stand by your word."
Melanie pushed him away from her. "Payback? What the hell is going on here? I thought we were making love. Sebastian and I didn't make love."
"You don't have to lie to me Melanie. It's okay. I've already forgiven you--"
"You forgive me?" She backed further away from him.
Sebastian began to smirk in the shadows.
"There's nothing to forgive. Sure we kissed--"
"It was more than that." Sebastian said.
"He tricked me." Melanie said. "He put his hands on me, we kissed, but we never made love."
Alex glared at his little brother. "You goddamn asshole. You wanted me to believe you had her! What the hell is going through that crazy head of yours?"
Sebastian backed away.
"I came back to find you, Melanie. It was after I ran away the first time, but I found you here, with him, together. I thought you had chosen him." He looked down to the sand, his face covered in moonlight and shadow. "And he wanted me to believe that. He wanted me to give up on you."
Melanie flung her arms around him. The smirk left Sebastian's face. His damn brother was proving harder than usual to separate from his girl.
"Jesus Christ." He said. "You guys can have each other. But if you think I'm going to pay for it, then you can forget about it."
Alex pressed his lips passionately to Melanie's. When they finished kissing, he turned his head around to his brother.
"Are you still here?" He said.
"Yeah. Inconvenient, isn't it?"
Alex glared at him. "It's like this, little brother. You do whatever the hell you want, but if you have any feelings at all for Melanie, other than wanting to bone her, if you ever want to see her again or have a relationship with me, your twin brother, then you better had stick by your word. If you don't? What the hell, we'll get by; don't you worry about us. We have each other and that's all that counts. You can cuddle up in bed at night with your corporate earnings statement."
