Suddenly, one of the sisters said "Hey, it's pretty damn hot in here! We've been in these clothes long enough!" And then she nonchalantly started undressing.
Other sisters and your girlfriend soon started undressing as well, while explaining " Oh... That's right! I forgot to tell you that me and my sisters always walk nude in our home. 
We just feel more comfy like this, so I hope that you won't mind~?". After all of the girls fully undressed, you noticed that the damp, musky smell present in the air instantly quadrupled, 
almost making your eyes water.
