He would learn, he was a fairly quick learner and so after a moment, his hand gripped around the base and gave Stiles' one quick stroke before tracing his tongue over the slit and drawing it into his mouth. He kept his tongue pressed against the underside, enveloping it with the rest of his mouth as he closed around it, drawing it back as far as he could manage which was about a couple fingers short of the base.
