For an Asian woman, the woman is very juicy and ripe. With all the diminutiveness of her build, her ass and legs look great in the cradle position! And besides experienced, funny and without complexes. Who would have refused to have fun with her? What's interesting, the man was never shown, unless you count the close-ups of his dick! So what's the basis for assuming it's the son?
When a chick has a deep throat and a great pussy, that's the key to great sex! I know it, 'cause I've had sex like that from a girl.)
