There's a ton of scenes, you can tell the timid strap-on stuff apart from the harder ones though. It's not really the girls fault or anything; they would be twice as good if the strap-on dildo's wern't like jello and they never seem to "strap-on" tight enough to the girl, can't keep a good rhythm going.
From what i've seen most of the girls on US can use them real well, hot. Sasha Grey and Amber Rayne too actually.
