Steve knew what he had and he knew it could be uncomfortable, downright painful if you weren't careful. It was easier now that lube was readily available, a little more complicated back in the 40's when lotion didn't quite cut it. But it was better now and Steve could make sure it was better for him, especially because they were in their own bed, not stealing a moment somewhere, anywhere they could.
It wasn't like he'd got it intending to use it here with him, sure a guy could hope, but it had just seemed like a safe idea to stock up on condoms and lube, just in case. "It's not work," Steve assured him as he leaned down to kiss the center of his chest where the reactor had once lived.
He kissed down, mouthing at the head of his cock but not lingering because what he wanted was to get his tongue in alongside his fingers. Steve's cheeks flushed at his own eagerness, but that wasn't about to stop him getting what he wanted. His hole was tight and Steve lapped at it gently, groaning at how he felt around his fingers.
