They were as identical in their mid twenties as they had been at birth; apart from one tiny detail. Ruth had a small dark birthmark high on one temple. It was the size of a pea and looked like someone had poked her with a whiteboard marker. She usually teased a wave of hair forward to cover it. Rita was unblemished. OK, maybe there were a few other even smaller differences, but they were barely discenible.
Ruth was single and had a boyfriend. She still lived with her parents. She worked in a factory, had lots girlfriends and always joked that God had marked her forehead so people could tell her apart from her twin sister. Rita was married to Jim and they were planning on starting a family next year. She was was a secretary at the same factory as Ruth, who was her best friend as well as her sister.
"Has he tried it yet?" asked Ruth.
"No, I can't persuade him. Jim's a great husband but thinks anal sex is dirty and refuses to try it. You're lucky your boyfriend is more adventurous."
"It's true Todd is the biggest dick and the best sex I've ever had. I'm moving in with him soon. He wants anal all the time and I love it!"
"Hmm, maybe I should take a lover; just the once - to see what anal is like before Jim and I begin making babies."
"Jim, remember I told you Hartleys would reward us for the best sales push ever?" said Rita. "Well they're even recognising the contribution from the factory floor this year."
"I do." replied Jim. "What's the prize then?"
"They're taking us all to London, to see Moulin Rouge."
"Great, when are you going?"
"Next Friday." she replied. "They're laying on half a dozen coaches and we're driving there straight from work."
