彼女がベッドにいる間に彼氏とセックスします

My date leaves me stranded so I go to my friend's house to fuck me but I find that he now has a girlfriend, I go to bed while she is in bed and he goes to shower but I sneak into the shower and we ride him right there, then I can't stand it and I go to the bed where the two of them are, And you want to see what happens in the end..?
