You're Mine (BoyXBoy)

(Warning: sex, yaoi, BoyXBoy, twinset)
Youngmin had been spending a lot of time with Minwoo and Kwangmin was starting to get jealous. He had told Youngmin multiple times that he didn't like how much time he was spending with Minwoo and Youngmin said he'd stop but it never happened. This was the last straw and Kwangmin decided to do something about it this time.
