My wife spent about 18 months in her late twenties backpacking across Australia - mostly staying in hostels, making cash from bartending and waitressing, and sleeping around.

She had a fling with a miner in one of the towns she lived in for a few months. He would head off to work for a 10ish days at a time then come home every 2nd weekend or so and they would hook up

During one of his visits they went to a pub to meet up with another couple. They all decided to head back to his place for a few more drinks in his hot tub

After a few more G&Ts the fellas drunkenly convinced the girls to put on a bit of a show. My wife and the other girl stripped down and made out while the guys watched. The boys eventually stripped down as well and the four of them spent the next hour or so making out naked in the hot tub before retiring to their respective rooms to fuck
