Potentially the Bilbao area should be good for punting. There are quite a few places listed on Wikisex, but I found things a bit tricky for several reasons, one being that most places don't seem to open until after 5 pm. Another was that the outcall escort scene does not have an informative online presence, at least in English. So here is what I did find out.
Went to CLUB DOÑA URRACA but it was closed. This was a bit of a let down as it was supposed to be the best brothel in the centre of town. Anyway, walked on round to HOTEL COSTA PELICANO, Calle Matxin 2-4. Walked past the guy at Reception straight on to the bar. The set up reminded me of Airport Girls in Berlin, but the place was cleaner and not sa smoke-filled. I got a bottle of water (cost 7 euro!) and a girl started talking to me. She did a bit of the "let's go and fuck now baby" routine which I find a bit irritating. Still, I kept my head and said that I would be taking my time and was in no rush. She seemed to think that was fair enough. Then I wandered towards a girl I did find attractive, but was stopped along the way by Ailine, a Romanian with nice knockers and a pleasant manner. After a few minutes I thought the chemistry worked so I paid a few euro for a towel and up we went to a room. The price was 150 euro for an hour with 20 extra for kissing. Pleasant bird, would have given OWO, but I asked for with. I ate her out for a good while, pounded her for a short while in Mish and then finished with a hand job. I should have come over her tits, but was enjoying the kissing. An OK punt, no complaints.
Ailine told me that she used to work at CLUB DOÑA URRACA, but that it was closed by the police. So Pelicano was a good alternative. Like all these places, take your time when you get in. I didn't make it to Valle de Trapaga outside the city due to work committments. Overall, I would like to go back to Bilbao and check out the other places.
