Sister Rodeo

When you are having sex with a woman doggystyle, you gently slide your thumb into her anus, then say, “I fucked your sister last night.” You then hold on for as long as possible.

Josh was having sex with Brandy, he broke the news of his last week’s infidelity with her sister Britt and had a sister rodeo.
