Occasional? I'd suggest you see it on all porn sites now and a lot worse! This content in magaluf is extremely tame compared to what can be found on any site online, as for escorts / prostitutes (whatever tag you give them) they see multiple clients in a day... meaning they engaged in multiple acts of oral sex, ok its not simultaneously!
Wouldn't it be better for main stream media to tackle the issue of prostitution? say, legalizing it and getting women out of grubby, illegal brothels? away from pimps and keeping them safe? Or making the porn industry regulated, dictating that all performers be made wear condoms? Aren't they far more pressing issues than one drunk girl being taken advantage of?
You address the issue then, why did this happen in a normal bar / club? Ideally it shouldn't be happening, but in these type of resorts abroad it does...I recall stories like this every summer now for the last few years or more. All since the break out of "Ibiza Uncovered" on Sky. Remember those two women who had slept with 30 blokes each, they we're made "mini celebs", they had their 5mins of fame. Around that time a group my mates and I went over to Corfu and there was outrage because some girl blew off 3 guys while they stood on the bar...that was literally in front of kids. That was about ten years back roughly, a curfew was put in place then after that. That same holiday in the town we we're in a girl was video'd banging two guys on the beach and everyone cheering them on... I've seen and heard tonnes of similar stories tbh!
If the owners want sex in their establishment they should just open up a swingers joint, logic would suggest that wouldn't line their grubby little pockets though and they go for a bar instead and run these "competitions" instead.
Magaluf isn't really for families, I'd not bring my family near it. I know what goes on there, if I was 18-25 again that'd probably suit me more...but adults with kids? stay far away!
