A famous photographer who once worked with my wife invites us to a busy shoot, but the male nude model never arrives. My wife's careless suggestion makes me the last-minute replacement, and I strip as instructed. Pressed against a busty former pinup model, I cannot hide my erection. She whispers that she has to make it go down before anyone notices, then services me during every five-minute break—even while my wife watches the monitor. Seduced by her sweet voice, I spend the entire day sneaking rushed sex and take ten creampies in this secret reverse-cuckold affair.
