A physics student had a rather different way of earning money over the summer after he was invited to star in a porn film while on holiday.
Luke-Kristopher Davis, a 21-year-old student at Swansea University, was approached by a porn director and offered the chance to make an erotic film.

The Oxford-born student was holidaying in Barcelona when he decided to take up porn film director Erika Lust on her offer, and ended up making two films.
"When it came to the performance [Erika] was very impressed and wanted me to work there for a long time," Davis told Wales Online.
Davis, who also tutors A-level students, added: "I had to think about whether the risk was worth it because when you go into that industry there is a risk that your reputation will be affected.
"But the science industry and physicians are relaxed. They only care if you are doing science well. They do not really care about your past.
The student previously told HuffPost UK: "I think these experiences may carry some risk for future employment, I took this into account the moment I was asked to perform. However, I believe the experience and contacts I've made outweigh the risk. If my plans for future hold ground, I don't think this experience will even matter."
Davis now has his own profile on porn site XConfessions, which reads: "The charming England native also dances and attends university when he is not wow-ing us with his great smile."
