Kel is pinned very effectively in place by steel clamped down tight over her tits. She still can’t help trying to pull away when I hit her breasts, belly, and thighs though, and those pulls *hurt*. The vibrator humming away does provide a bit of distraction because I’m not an awful person.
(Don’t miss at about 3:30 when she yanks back in response to a hard stroke across her belly. If you listen very closely, you can *hear* the pull she gives her own tits.)
