Mia whimpered, because yes she was focused on how good Tripp felt but he was also still inside her, and it felt really, really good every time he moved. She was getting a little desperate herself, and was just about resisting the urge to rock up against him.
George moaned as he pressed completely into Tripp, his hands gripping the other man's hip. "Mia, stay still, but spread your legs and tilt your hips up. I'll set the pace for all of us. Tripp, dear... just let us guide you."
He pulled back, taking Tripp with him for part of the way before pulling out a little more, and then pressed back in.
