I've messaged her from my punting email address. She requires a face photo of you and makes a reference to needing a £20 deposit (although mainly if you cancel and want to book again). She also seems to indirectly hint at bareback being on offer.
Seems like a scam - I'm sure you'll be rinsed for a deposit and/or blackmailed with your face pic. It could be genuine though as she doesn't promise everything under the sun service-wise (she lists stuff she doesn't do but only extreme stuff like BDSM and watersports - everything else she claims to be gagging for) and she sends other pics where you can clearly see her face and she's definitely not a looker (but all of that could just be deliberate to make you think it is real). Based on all that, whatever she is, she's definitely not someone worth seeing.
