I introduced another Asian girl to my white guy friend because I wanted to stop having sex with him.

I've been having sex with this white guy friend and honestly it was all fun and dandy but I just wanted to move on, and the thing is, he never did anything wrong. He was handsome, tall and sweet and I know it was going to break his heart if I suddenly refused to see him. We are not in a committed relationship. It was solely sexual but still, I didn't want to hurt his feelings.
I've always been a very polite person and I always have a hard time saying no directly to someone. I had the option to simply ignore him, which is very rude of course and I never do this unless the person really pissed me off. And so I came up with another idea: I know this asian girlfriend of mine who has never been with white guys and I told her about this hot, attractive white guy who is the sweetest man in the world and initially she refused but I know her asian boyfriend just broke up with her and she was on rebound and so I kept egging her on, telling her how wonderful white guys are, how much better the sex is, how much more emotionally satisfied she would be.
Eventually she relented and she met with my white guy friend and we ended up having a threesome.
And of course my white guy didn't embarrass me during the threesome. The first thing he did was crawl under her skirt and eat her out. She was so shy she kept on pushing his head away but he made her feel so good she ended up cumming on his tongue, and after that he took out his big white cock and started pounding her. I watched both of them on the sideline, those two love birds fucking the brains out of each other and I masturbated myself and then afterward I joined the action by sucking on his cock. My girlfriend and I shared his cock between our mouths and gave him a blowjob sandwich.
After the sex I asked my asian friend how it was and she said his white cock was too big and the sex was too painful, and I told her that it's okay, I was just like her initially but she will get used to it eventually and will never be able to go back to anything smaller.
They officially started dating and are now obsessed with each other to the point they are considering getting married, and I started to see other guys so in the end it all worked out swell.
