Do as she says

You do as she says and unload into her asshole. You hold in for a second as you both moan, then slip back out. Mary-Jane stays bent over for a minute to recover. "I think I win." she says.
"Yeah I agree." Natasha adds, feeling horny after watching the show.
"Yeah, Mary-Jane has the better ass." You confirm.
"Yay!" Mary-Jane celebrates as she straightens up. "I better get back to my husband! He'll be waiting for me!" She quickly washes herself off then runs out the shower leaving you and a horny Black Widow all alone.
