My boyfriend told me I can fuck a black guy

F20, my boyfriend is white and we have been together for a long time and recently iv been getting really horny thhinking about taking a big black cock up my ass. I got a anal plug that says bbc only on it and I wear it at night while he’s gone and I talk to black guys to make me cum it felt so dirty bc he didn’t know I was doing that, but last night I told him about this and it really turned him on so I told him that I want to fuck a black guy for real and he said it would be so hot if they could stretch out my tight little ass hole more than he can and make me be bbc owned
