Saw Selena the other day and I have to concur with the OP.
Good comms, text send you more or less to her front door and then you call for the flat number. Convenient for the tube and, while on a main street, no-one pays any attention to you.
Once inside, Selena's immaculately groomed, friendly and offers shower with a clean (but small) towel and the usual array of shower gels. Unusually the shower regulator works fine and it's easy to get as hot or cool a shower as you wish.
Upon re-entering the room I got my one and only disappointment of the encounter - she was waiting naked on the bed for me. I like to unwrap my presents slowly but how was she to know... Anyway, slim, tanned, small perfectly-formed tits, very nice arse. Note she has an unobtrusive tattoo on her side and a big one on her back, in case anyone finds tatts a turn-off.
I opted for an hour of lazy foreplay, much like the OP, culminating with a few minutes' cowgirl. I couldn't really fault any part of her technique: she doesn't use her hands overmuch on the BJ and is quite happy to let them be gently brushed away if I felt there was too much hand action; she's very attuned to your needs so position changes happen naturally and gracefully; who knows whether these girls ever really get into it - I assume not - but there was never a sense that any of it was a chore (and there were at least two 10-minute OWO sessions).
All in all, an excellent punt and at £80 good value.
