A dream and some relationship talk.

Alan was sawing his engorged member into the nubile girl writhing below him. Her screams and moans filled the air as she met his every thrust with her hips. Her face was contorted in pleasure, her hands roamed his chest. She looked up at him. He could see the exotic face of his feline lover Luna, piercing lust in her eyes. She bit her lip, whimpered and mewled. A moment later, her features blurred, and they changed. He suddenly saw a new face: pale green eyes, a corner of the mouth raised in a smirk. It was Catrina. ‘Make love to me, little brother,’ she moaned between his thrusts.

Alan startled from his slumber, cold sweat on his brow. A slender arm was draped over his chest and he could feel the even breath of his lover on his neck. He looked down at his companion. It was Luna—not his sister, god-forbid. It was just a nightmare. Her face was so utterly tranquil it pained him that he had to wake her.
 They were both still naked, he could not even remember how many times they had sex that night—Luna didn’t lie when she said they had to make the most of it. His shaft was painfully hard—did the dream really affect him that much? He gently nudged Luna’s arm, trying to coax her from slumber. She stirred but only murmured something indecipherable. He tried again with more vigour and her eyes opened a sliver.
 ‘Morning, Luna. Time to get up,’ he whispered to her.
 A broad smile formed on her lips, ‘Hey, Al. Can’t we stay here longer? You’re such a comfy pillow.’ She snuggled even closer to him.
 ‘I’d love to, but we have to get going again soon,’ he chuckled, ‘Probably could to with a bath after last night.’
 ‘Yeah, you’re filthy,’ she laughed.
 ‘Before that though,’ he sighed, ‘There’s something else we should talk about.’
 ‘O, what would that be?’ she asked.
 ‘Us, Luna. I’d like to know were we stand,’ he told her, ‘I—I’m kind of new to this whole relationship business. And, well, I like you and we had sex and—’
 She stopped his rambling with her finger to his lips. ‘I get it. This is all a bit much for you, huh? What do you want us to be, Al? A couple? Lovers? Friends who have sex?’ He wanted to say something before she shushed him again. ‘Before you answer, there’s something you need to know,’ she took a deep breath, ‘Catrina and I are lovers.’
 His eyes bulged at the revelation, ‘C—Cat and you? I mean, you’re both women. And—O, no. Doesn’t that mean you’re cheating on my sister?!’
 Luna rolled her eyes, ‘Well, yes and no. She has sex with other people all the time. And I do too occasionally,’ she winked at him, ‘But those are just physical relationships, they’re just more elaborate masturbation if you think about it.’ She frowned, ‘I do feel a little guilty about this, though. It’s not just sex with you, Alan.’
 Alan was quiet for a moment, he felt conflicted. He didn’t regret what they had done but he hadn’t known about Luna’s relationship with his sister at that time. ‘Right, look. I really enjoyed what we did, and I’d love to do it again, obviously. But I think maybe we should not do this again until we had a chance to discuss it all with Cat, alright? I owe it to her not to have an affair with her lover behind her back,’ he sighed.
 Luna looked deeply into his eyes and could only see sincerity there. She cupped his cheek and said, ‘She really doesn’t deserve a brother like you, Alan. I’m not sure I want to wait that long, but I’ll respect your wishes—under one condition.’
 Alan raised an eyebrow, ‘That would be?’
 ‘We still get to cuddle,’ she grinned.
 ‘How can I say no to that?’ he agreed.

They got themselves ready to continue the journey and soon the coach set off from the roadside brothel again.
