Hali and Riley are both stripped down to their tank top and sexy thongs. Both girls are doggy style on all fours and have their bare asses pressed against the others. Both Hali and Riley think THEIR ass is stronger and sexier than the others and they are going to put their asses to the ultimate test to prove it! They bump asses starting out slow then get faster and harder so we can see the waves off their skin with each bump! They try to push their opponent off the yoga mat by grinding, wiggling, and pressing their ass as hard as they can into the other girls. Who will win this butt battle?
