My Boyfriend wants to share me?

[aisha_sugarlips]

Last week he showed me a porn video and ever since he has been mentioning me to indulge in the act. He wants to share me with his gym buddies. He said he has already spoken to them and they are fine with it. He is waiting for my answer. The say he showed me the video, I jokingly agreed, but now I am scared. That would be just me and 6 guys including my boyfriend. All of them are extremely built and tall. What should I do? Please help me.
