Nathan fails his math test, so Paul is enlisted to teach him a thing or two about numbers, counting each hard slap to the ass until Nathan's boy butt is almost blue. Trouble is with each spank, Nathan becomes more and more turned on and loses count. Dominant muscle stud Paul then forces Nathan to suck his cock just the way he likes it. Nathan takes more abuse to his burning boy cheeks in the form of swats with a belt on his already raw flesh.
The burn must be excruciating, but the horny twink is a trooper. Paul is especially merciless with this particular little bubble butt. Paul breaks from the ass abuse momentarily to tongue the poor boy's hole, preparing it for an incredibly hard fuck, the kind only naughty boys deserve. In true SpankThis fashion, Nathan gets his red and burning butt slammed by the brut disciplinarian and is left with his butt burning red, and a face full of cum.
