"I can't!" Irina was really at her limit, because she was so focused she didn't realize that Ryan just wanted to see her bubbly bottom cheeks from behind.
"Alright then, hold your position and now shake your waist."
"Ah?" Irina was shocked at his words.
"Honey, this is to train your waist and thigh muscles. Later you will feel the benefits when it's finished." Ryan said in a convincing tone.
"Okay." Even though her current position was embarrassing, Irina endured the shame for the sake of her ideal body and did it according to Ryan's direction.
Ryan watched the round cheeks shaking violently!
"Yes, that's the way! Great!" Ryan's praise was neither clearly directed at Irina's efforts or shaking ass. But it was clear that the guy gave a score of 100 for that soft ass.
After a while, Irina got tired and stopped. Ryan immediately looked away, "Alright for the next time we train your back muscles, we will try a backbend."
