Brother in-law on my taste buds

I’ve been living with my twin sister since June. I lost my job and her husband hired me so we all work from their house. I have my own room away from them and all to many of their children, which is very peaceful. But a couple night a week my sister’s husband come to my room to collect rent. He has a beautiful cock that I’d love to have inside me, but I hate condoms and he always makes a kid when he cums. So I let him fill my throat whenever he wants, my sister doesn’t suck dick. Her loss is my gain.
