I wake up in bed and I realize I'm tied up. Hand and feet in chains, I don't know what happened but this already make me HORNY. I try to free myself and at first I can't. I try again and I put all STRENGHT into it. In the menatime I see that as I STRUGGLE, my MUSCLES CONTRACT and GROW... BICEPS, QUADS, even my ABS are so contracted and this turns me crazy!
