Dating twins didn't know at first
I started dating a girl, i say date, it was fucking really, basically i called at hers or she called at mine, always quite late so we had sex and fell asleep. I didn't realise she was a twin until she confessed that her sister had taken her place when she was busy one time, and then they kept it up, switching places. I thought she had an insatiable sexual appetite, turns out i was fucking twins and didn't know it.
When they told me, a number of odd things made sense suddenly. I pushed my luck and asked for a threesome, which i was shocked to get a 'yes' in response. Omg that was amazing. We talked after and decided it could be an ongoing thing. We are now in a three way relationship and share a flat. It's tiring but I'm very happy.
