My bf caught me sending pictures and punished my ass

I was horny exchanging messages and pictures with a boy I met. My boyfriend saw me and was furious. He wanted to punish me, made me suck his cock hard, ordered me to stick my finger in my ass, I confess I was scared but seeing him like that made me much hornier. So he fucked my ass hard, it started hurting, but the pleasure was much greater and when I realized I was already on his dick. I got a wonderful punishment and my boyfriend was pissed that I liked it.
