mate she must have been on an off day. i've had the pleasure a few times and while she's not as good as ivanna she looks and fucks great. does a very slow and sensual bj and has a lovely arse IMO. not sure why she was like that with you. she recognises me when i go in so i might be one of the lucky ones but im sorry to hear you had a bad experience of her.
I wouldn't say it was a bad experience, it's just one that's unlikely to be repeated in the future. I did enjoy myself and as I said it is a harsh neutral but still, I didn't find anything to be that great, except possibly her looks.
It's probably more horses for courses than anything else. Having said that, I agree that her arse is lovely and her BJ technique is good (as I said). Has she provided you with prolonged and enthusiastic FK or DFK? If so, was it first visit? I should point out that I wasn't expecting this but I was still hoping for it, which is probably quite stupid in a parlour, especially one like Cosmo (not that I think it's that bad). Still, DFK is almost par for the course at a place like Sheridan's (which is also cheaper and includes OWO in the basic price).
Moving on from her, do you know when Ivanna usually works? I'd probably like to see her again (although her enthusiasm is hardly top notch either but it is a bit better). Also, do you know when Zoe works (if she's still working)? Her service is pretty poor but she is fit as fuck (IMO).
