Cool topic, For me most have been mentioned – needles bloodplay etc – no way and gas masks yuck – I dont get it? Also really dont like schoolgirl stuff even when the model is obviously not a school girl
One I dont think has been specifically mentioned is men groping a tied up girl – in a “happy to be tied up scenario” it is OK I guess but Its just to close to nastyness otherwise – I just dont want to see it.
On a similar yet opposing vein; tickling – a total turn off for me another one I just dont get
