He started serving them a couple months ago. It began naturally enough. He had them over to his place for a drink. He obviously served them and worked to make them feel welcome. Thing of it was, it continued for the rest of the evening. "Can we just pretend we're at your place and ask your for refills?" he was asked when they went out. His personality was that of a pleaser so happily agreed.
A couple days later they were at the beach and it continued. That night, they fucked him for the first time. After all three of them got off and they were all leaving his place, the one holding his hand said, "Next time we're at the beach, wear a speedo. That's how a good boy dresses." Instinctively he responded, "Yes Sir."
Later tonight, they're going to cage him and make him a proper faggot. He knows it too. He's excited as they are going to finally make him live like he should. It will help him focus on his responsibilities. Three men have lots of needs and it's his role to ensure they are met.
