Finally, what he'd been waiting for the entire time. Tony's hands grasped her waist as she sank down on top of his cock, groaning as she took every inch of him and slid back up, licking his lips at the beautiful sight. He watched Kirk move into place right behind Remy, waiting anxiously for when he could get in on this so while the man positioned himself, he sat up just a little to kiss her and occupy her while he did so.
Behind her, Kirk stroked his cock and lubed it up nicely before he pressed the head against her, slowly working it inside of her, relieved when he'd pushed past the ring of muscle and breached her. He gave her a little time to adjust before trying to work a little more in until he was almost completely buried in her. God, she was still so tight, and he thought he might lose it just then before he was pulling out and thrusting back inside of her.
Below, Tony watched Kirk's rhythm and started his own, timing his thrusts so that as Kirk was pulling out, he was going in. One hand braced on her hip, the other cupped her breast, kneading it mercilessly before he moved to bite and suck at her neck.
