[synopsis]
I grew up with a good friend of mine who was a good friend of mine. He married my best friend and has been married ever since.

One day, me, my best friend, and my girlfriend were supposed to have a drink at my house, but my best friend couldn’t make it due to some inconvenience, so my girlfriend and I ended up having a drink together.

While we were drinking together, I became aware of my girlfriend’s voluptuous body as a “woman" for the first time.

Her female friend notices this and teases her by showing off her body.

After a night of drinking, my girlfriend gets drunk and ends up in bed, but she’s staying at my house today.
I made that call to my girlfriend’s husband and went back to bed, where I found my girlfriend silently seducing me with her underwear exposed.

Both of our reasoning was blown away, and we began a night of sordid, beastly copulation.
