#1, rated M: Engineer, Spy.
There is no room for words in the short space between them, but the Engineer tries to fit them in anyway, mouth pressed to the Spy's skin, lips betraying feelings best kept secret but which force themselves past his tongue and teeth. His efforts are met with hisses, with a hand on the back of his neck tugging him closer, with hips rubbing against his. Warm skin, slick with sweat, slides together; quiet slaps echo throughout the room with movement; sheets rustle; the mattress creaks. Spy's grip is as sharp as his groan when he finishes, pulling Engineer with him.
