In Book 4 of the Sexy Giant series our hero Jack Scoggins decides he's through being the sex toy of the giantess Mistress Sylvie. He goes on a sex strike, but Sylvie retaliates by putting him in a chastity device, then driving him mad with sexual desire for her and her giantess girlfriends. Jack is stuck in Sylvie's girdle and he's an unwilling participant in a sex orgy that involves a roomful of horny, drunken giantesses. It's a sexy, funny tale that has Jack smiling at the end.
