Alice endures for Sir.
Alice is a special sort of creature. Being naked in front of the camera is embarrassing for her. He makes her strip for him. She overcomes her humiliation for his pleasure. She tries to hide her face. The embarrassment turns her on. She rubs herself.
He wraps her in leather so tight she has trouble breathing. She endures for his amusement. He hooks her ass with metal while she blackens his boots. She does a good job and is given the reward of an orgasm. It’s not easy for her. She has to expose herself to do it. As she rubs her clit for him she cries sweet tears of humiliation.
Suffering for his amusement is a mixed treat for Alice. She loves the pain, she loves the pleasure she sees in his eyes, but she must endure a lot for him. He spreads her legs in an impossible split. She’s so exposed. Then he hurts her.
