My step-sister Cara and I love to wrestle in our undies. We love to rub our butts together so you can see just how strong our asses and thighs have been getting. We have a couple rounds to show you who has the stronger butt!!!! We have a round of standing and shoving our butts together, a round where we shove each other side to side with our butts, squat position and shoving, and last we get on our hands and knees and push the other out of the wrestling ring with our asses! We can get a bit competitive ;)
