cum for me, Merlin," I whispered into her ear. "Please."
"Yes, cum for us, Merlin," said Serena, kneeling beside her. "He's fucking your cunt, cum."
"oh my god, oh my god, I'm coming, yes, yes, yes!"
Her orgasm broke, and I felt her muscles tighten around me. I stopped, knowing that if I carried on much longer, I would be in danger of coming myself. And the night was too young for that.
Merlin shuddered and shivered beneath me, and I kissed her sweaty brow tenderly.
"Thank you," she said. "Thank you. I needed that."
"Well, what about me?" wailed Serena from behind me. I laughed; I couldn't help it. Merlin laughed too, and then gasped as a secondary wave of smaller orgasms seemed to pass through her.
"All right, Serena," she said. "You can have him now."
I pulled myself gently out of her. My cock glistened in the firelight with her juices. Liana's eyes gleamed.
"Just a sec, Serena," she said. "Let me get him ready for you."
