My F22 boyfriend's dad cums inside of me every time he fucks me raw

And he fucks me raw all the time. My boyfriend's daddy might as well be my second boyfriend from all the times he gets to pound my pussy and fill me up whenever he wants. He fucks me so much more often than my own boyfriend and I have no regrets because it's too fucking amazing!
We first started having sex around December of last year when my boyfriend started working late shifts.
I live with him and his dad so all of a sudden I'd be home alone with his dad and we got closer as a result. It was normal at first, but quickly turned flirtatious when he'd compliment my looks and outfits and I'd do the same for him. We'd hang out and watch tv and movies together. Eventually l'd wear more revealing outfits and he started to hug me tighter and then spank me, which got me wet instantly.
One night we're watching a movie and the sexual tension was too strong. Before I knew it, we were making out and getting hot and heavy. We stopped and agreed to keep it a secret from my boyfriend.
That night he gave me the best sex ever as we kept it going until he finally pulled my panties to the side and fucked me as he picked me up and pounded me on the wall.
He took me to my boyfriend's room and fucked me doggystyle on his bed as he spanked me and pulled my hair. From then on, we started an amazing sexual relationship as we fucked multiple times every week and even started to go out and fuck in his car and sometimes hotels.
It's been such a hot risk to be enjoying daddy's dick and sometimes after he cums deep inside me, I ride my boyfriend's cock and just enjoy the absolute euphoria of mixing their cum together. I love being a daddy's girl.
