My sister has a beautiful ass, no, a super beautiful ass! It's a godly ass! And yet, when I see it in front of me every day, I get a boner! And it's a thong! I couldn't hold back any longer, so I pulled down my sister's panties and inserted myself raw from behind! At first, she was reluctant, but she felt so much from my hard thrusts that she had multiple explosive orgasms! When I see a godly ass like that, it doesn't matter if we're brother and sister! I want to fondle it! I want to fuck it! That's what a man really wants.
