Black Widow's are better

After having a good feel of both you make a decision. "Natasha's are better." You tell the girls.
"What?" Mary-Jane seems offended even though she was arguing for Natasha's. "Okay okay, but I have the better ass right?" Mary-Jane turns around, puts her hands on the wall and sticks her butt out. Black Widow tuts but then does the same. Both of them have very tight, round asses. You give them both a squeeze. Mary-Jane's has a little more to grab hold of. Then you give them both a smack. Black Widow clearly has a firmer ass. "Well...?" Mary-Jane questions.
