Eames's hand continued it's motions, squeezing Arthur's cock every so often to interrupt the rhythm. His lips and tongue and teeth tracing the muscles of his neck, giving every rise and fall of skin the attention it needed. His free hand rested on Arthur's hips, holding him in place. He loved him like this, the open target of his advances, and having Ariadne helping...

It wasn't nearly as unwelcome as he had expected.

He glanced at Ariadne again and, with a twinkle in his eyes pulled Ariadne's lips away from Arthur's to kiss her himself. In the moment when he was pulling away he leaned into her ear and whispered something, smirking as he pulled away and returned to Arthur's neck.
