barretthunter has a *ton* of stories (200+ including stories and serials), all of which feature big bottomed spankees. His stories tend to be a bit on the more intense side, often involving undeserved spankings, and nonconsensual sex, but if you like or can tolerate those, many of them are great reads.
It's not explicitly spelled out, but some of Gloup's stories seem to suggest that the spankee has big butts, though he doesn't quite make it as explicit as barretthunter (a lot of his bottom descriptions emphasize how round the bottom is, with occasional mentions of protruding derriers). Though a lot of his stuff also involves mistaken age, so those spankees are obviously going to be smaller.
A few stories that come to mind that make me think the spankee has a big butt are: Dungeons and Dragons and Red Bottoms, The Full Waxing, Gaming Addiction, and Hell on Halloween. Though again, Gloup isn't as blatant about it as barretthunter, not sure they'll meet your criteria. |
