Men's friendship is strong! But my best friend's cute girlfriend is the one who asked me out, so I can't help it! I was worried about my best friend, but I got into the mood. The excitement of secretly playing with each other's private parts, the guilt of pretending to my best friend that nothing happened, and the tension of not wanting to be found out made me many times more excited than regular sex, and it was so crazy that she was trying so hard to hold back her desperate voice!
