An Energetic Karen and Noa - Part 5

After having him remove his trousers, noa stands in front of him and knees him in the balls while karen stands behind him and kicks him in the balls from behind. they keep doing this in turn until one of noa's knees cause a critical hit which causes him to scream and roll on the bed in pain. noa asks if he's hurt (in japanese) and he checks himself and checks his cock and balls are fine. they have him turn around to face karen who now knees him in the balls while noa kicks him. noa holds one foot against his back to keep him moving while kicking the other foot into his balls from behind. they speed up their kicks and knees towards the end.
