New girl from the church turned 18 and I made her suck cock, she's learning well, her boyfriend doesn't know

She is a friend who has just turned 18 years old, we have known each other for a couple of years because we go to the same church, she already told me a long time ago that she liked me, I had to wait for it to be legal to finally be able to her properly, the wait was worth it, Now this girl is getting addicted to me, her boyfriend thinks she's in church.
