Having noticed that Wimbledon is going on right now (even though I don’t actually follow it) I’m inspired to suggest “models bound in tennis outfits.”
Sans shoes & socks, of course 🙂 🙂 🙂 Or possibly with shoes, socks, and tops taken away before the bonds are applied.
It might be a storyline where tennis players are desirable pieces of merchandise for Honest Omar’s customers. Or it might be a storyline where all tennis players are slave women for some reason or another (“No free woman would wear such scandalous clothing in public. And no free women would put up with the rigors of training required to be a first-class women’s tennis player.”) So tennis coaches own slaves, or chains of slaves.
