She arched her back like a cat, her legs slightly apart, sticking out her butt. She had white fur handcuffs on her wrists. The chains hung down from above, leaving a wide gap between her thighs. She had a slightly uncertain but defiant expression, blushing slightly. The lighting was perfect. A young, thin student stood behind his 35-year-old lover. A short, clean-shaven, thin young man of about 19, with an erect penis, groped her breasts with one hand and stroked her pussy with his other hand.
