I can't believe I'm thinking about making a move on my sister's super cute friend who she's really close with. If she found out, it would be the end of me... But this 'forbidden' feeling is incredibly exciting! I feel bad for my friend, knowing it's wrong to think this way about my sister, but for some reason, I can't help but get so turned on that my panties are soaked with love juices... I just can't resist this sinful erection situation! I'm going to let it all out until I climax!!
