Sushii and Kitty are both working out doing sit-ups and after seeing the ones belly, Kitty takes over. Kitty ties Sushii up, arms stretched above her head. She kisses Su's belly a bit before fingering her belly button and kneading her belly. Kitty gets really excited and great joy from loving and punishing Sushii.

She kisses Su's belly a bit before fingering her belly button and kneading her belly. Kitty gets really excited and great joy from loving and punishing Sushii. Kitty switches from standing in front of Sushii and standing behind her. Su is turned on by the play and Kitty loves bringing her to the edge. But she isn't satisfied. So midway through Kitty takes Sushii down and puts her into an over the knee back breaker hold, really stretching Sushii out. Sushii cries in pain from the stretch and Kitty pushes her to the edge. Kitty then starts fingering Su's belly button deep again the roughly kneading her belly. Sushii is still hurting but is beginning to enjoy it. Kitty kisses sushii's belly button a bit too. Eventually Kitty really stretches Su out and the fingering becomes so intense that Sushii orgasms. Kitty let's her slave go free and Sushii grabs her, kissing her passionately.

NOTE:
So kneading especially is grabbing and squeezing the belly. Like digging their hand into the belly. Kinda like how a cook works with bread dough. Some people call this light belly clawing.
