I'm going to wake my sleeping friend and make her get out of my bed when my so comes home.
Why be so rude to your friend?
I don't care what she wants, I'll fucking do this because I don't want to get busted by my so.
She shouldn't be hiding from your partner. That just makes you look guilty of cheating on your partner with your friend.
So, what if I am cheating on her, but I am still going to hide it.
Hiding this girl that you are having sex with is just wrong because you are not being faithful to your so. Stop your cheating or end the relationship, but don't be dishonest.
