This happened a few years ago, so this is technically my ex, names have been changed, etc. We were 24 and 22 at the time.
So one weekend my girlfriend Melody and I went with her family to her grandfathers cabin in the mountains. This place was a quintessential old fashioned, good country time with guns to shoot, lakes to swim and fish, deer roaming around.
The cabin was small however, and with her parents, aunts, and grandfather all there, it left little time or space for privacy.
