Very nice video. Yes she moves about a bit but keeps her butt up for the most part, she doesn't really cry out and only kicks a leg up once. Is she lying directly on top of a stuffed animal? (the blue and white thing).
Yep, it's a tawse. Though in the right hands it can be some much worse than a belt. The girl is clenching her cheeks too much that's why you have to fig them first. Nice little ass though, very lovely and made for a good whipping.
