Either I'm in Him or He's in Me -Our Offensive and Defensive Battle!-

Aki and Hayato have been friends since they were kids, and compete against each other in sports, studies, and anything else imaginable. Aki's also always interrupting Hayato's dating life, and it really annoys me! But then, one day, Aki suddenly pushes Hayato down and asks him if he wants to be with him. Aki's kisses and touch are so gentle and feel so good, and he feels himself getting excited... Wait, why is Hayato feeling flustered over his rival!? Hayato wants to take the lead, but Aki won't let him... Are they gonna have an offensive and defensive battle in bed?
