Isosceles Threesome

A threesome involving two identical twins, so you have two identical sides of the triangle.

I just had the best night of my life. The Karlsson twins got drunk and I slept with both of them. I know you're not supposed to be able to tell them apart in an isosceles threesome, but I swear Astrid is better in bed than Elsa.
