Szwagierka pyta mnie, czy ma lepszy tyłek niż jej siostra i tańczy dla mnie, więc mogę ją lepiej zobaczyć i przelecieć

My sister-in-law is always competitive with my wife, but this time she has reached the extreme that she asks me which ass is better, hers or her sister's, and to show that hers is better, she shakes it and lets me fuck her so I know that her ass is the best
