To be honest the Avengers Tower was probably the safest place for them to do anything in the hallway but Steve didn't want his first time with Sean to be like that. Not that part of it didn't have some sort of forbidden thrill but he wanted them to be able to focus on each other, to take their time. Or at least rush through everything in private.

Steve tried not to grind too much against Sean's leg but it was hard not to, the friction so absolutely perfect. And it was probably best that Sean was opening the door because Steve was too distracted by the feel of Sean's erection against him, how is body felt pressed so close. Once the door opened behind him Steve stepped back quickly, pulling Sean with him before turning to press the other man against the wall and kicking the door closed in one motion.

Now in private his hands slid up under Sean's shirt, fingers trailing along the skin and muscle there, taking in the novelty and the excitement of it all.
