彼女が私を見守っているのは、私が彼女の友人と浮気しているときです

I thought my girlfriend was away, but she came back and spied on me as I was fucking her best friend. I did not know she was watching us as I kissed her friend, she sucked my cock, and I fucked her till I came in here. My girlfriend played with her pussy as she spied on us.
