The married woman resists the gym trainer’s sexual-harassment lessons, saying she is a wife. Muscle pistons give her orgasms she never had with her husband. The back piston especially makes her spasm, sweat and squirt as her uterus is pumped. Semen that is not her husband’s is poured into her. Drowning in pleasure she still goes to the gym today to be taken, while her anxious husband waits. She even lies that it is his birthday so she can receive protein ejaculation after hours.
