I'd love to have my sister-in-law do this to me - while her husband, my brother, watched it all happening .... along with all the girls I fucked in high school and college watching as my sister entertained my ass and my cock for all to see.
She isn't wearing a wedding ring. If i was him I'd be proposing to her right after she made me cum. She is definitely wife material if she is willing to lick and probe his asshole while milking his cock and balls
