Shiro, you horndog you! (Oneshot)

((SMUT)) So basically, Shiro gets horny when him and Lance hand wrestle. Because who doesn't get horny af after a good hand wrestle amirite?. Lance says that the loser has to do anything the winner says. You know where that goes. Shiro takes full advantage of this and smut happens, as well as fluff, cuzz who doesn't love a good fluff.
