He let Saber take over

"But Dr. Valentine also said I should stay in character as long as I'm undisturbed." John remembered his therapist's words. "And Saber didn't feel ashamed of walking around like this." John's expression became more pleased and his voice got a little higher. "Saber felt good about people liking how good she is looking. Saber has such a sexy body and it would be a shame not to show it." John's mindset and voice had changed into the ones he had just a few minutes ago. He took of the jacket and looked down on his fit body. "If I was a boy I would also check myself out." He reached to his back and undid the zipper of the top. He let it fall to the ground. "Just look at these two girls." He faced down on his two big breasts and gently run his hands over their soft skin. "They are perfect for a body like mine."
