Don't try and struggle, those cuffs have you locked in place nicely. Hmmm, what's this? Your cock is almost ready for me. No? If you don't want me to, why is it hard? I'll wrap my mouth over it and make it unbearable stiff. Now it's ready. It belongs to me and I'll ride it if I want to until you cum inside me. Hah! That's a good boy, rest up, I'll be back later to use you again.
