Iona Grace. Wow. This sparkly-eyed 19-year-old has flawless skin and some of the biggest, prettiest all-natural tits we've seen. Something in those eyes yearns to be taught, to be shown things about the world. Today, we teach a lesson about the Sybian, and what happens when you keep it running long after you orgasm. We place Iona on the Sybian and construct a metal device to hold her in place, no pushing up off the vibrator, no mercy. We chain her hands up behind her, stressing her arms in strappado. Big tits pretty much beg to be drooled on, so we tie a funnel gag tight in her mouth. Iona's tits being as magnificent as they are, laws of nature require us to flog and whip the shit out of those pink-tipped beauties. And whip we do. Then we clamp those rosey nipples and cane Iona's feet. The Sybian works it's special magic. Iona has a hard orgasm. And another. But after a while, Iona's pussy is red and raw from cumming, and the Sybian doesn't seem so wonderful anymore, does it, class?
