Sexy Ava Nyx has been spanked OTK, then had to bend over for a harsh spanking with a thick yardstick, and her spandex-clad bottom is very, very sore.

Now she just lie in her tummy and get a seat-sizzling 36 swats with a stinging leather crop. The super-thin, stretched-tight red spandex pants prove a wonderful visual, but very little protection for Ava's poor, sore bottom.

Every 12 swats, Ava rubs her burning buns.

Next, the wooden paddle!!
