It could be many things - If the pair are stopped for a broken tail light, and it turns out there is an arrest warrant out for one or the other, that would be unexpected.
Tying someone up in an awkward position (such as bent over a chair, or impaled on a dildo pole), then having them move from something may cause a broken bone. How do you explain that on a hospital injury report?
Twists are possible, but are all character and plot dependent.

Say the heroine(s) don't know a shit about BDSM; they always control every situation they are in, then suddenly, they have that control taken away from them, and they relunctantly come to enjoy and then crave it? Do you think that would that be a real juicer for the majority of the readers? For me, this would seem to be an expected ending and not a real surprise twist. Just asking...
