Rumlow had never done this before, though he had been on the receiving end of a few from the women he was dating at the time. It didn't seem difficult of a task. Just suck and bob and try not to choke by going too low too fast or something.

Steve apparently didn't mind his boldness, which was a good sign. He latched his mouth around the head and sucked, wrinkling his nose at the taste of pre-cum and the texture. It was... interesting, but he diligently ran his tongue over the smooth skin and accidentally teased the slit between sucking in his cheeks.
