I want to have s** with my girlfriend's sister.
I'm a lesbian who is in a loving and committed relationship with the love of my life. She is wonderful and we are completely in love. However, her younger sister (who is my age) is also a lesbian and I have had a problem since the beginning: I want to have s**, and maybe even a relationship with her sister. I feel like in another life her sister and I could be each other's true loves. I know this will never come to fruition, but I think about it sometimes and want to get it out on paper, at least to some lonely corner of the internet so I can maybe let it go a bit.
