I’ve been with my girlfriend for 2 1/2 years, we got engaged last august on holiday and we are expecting our first child in May. My life was perfect until about two months ago, when I did a bad thing.
As my girlfriend didn’t want to go I invited her sister along to the office Christmas do. The evening was fab and the drinks were flowing big time, this is when the open flirting started. We all went clubbing but I only had eyes for her. We danced very close most of the night and at 3am we headed home, dropping her off first. She offered me a drink as a thank you for a good night.
As soon as we got in the door and away from the rest of the world the atmosphere changed, were all over each other in seconds. It wasn’t long before we were naked on the sofa having the most amazing sex. She then moved things to bedroom where we spent the rest of the night exploring each others bodies. It felt so right that I told her how I had always liked her, that she was so much better than her sister and that if there wasn’t a baby involved I would never go home. She said she felt the same but had kept quiet because of her boyfriend and her sister’s feelings.
We have met up over the weeks since, and the sex is just fabulous. I think I could really be in love with her. I’ve got my girlfriend who I love, and there is of course our baby but I’m in love with her sister. I need advice, what do I do?
