Isn't it ladies' sauna today? Spontaneous group sex in the sauna

I was in the sauna with my girls and when it's that hot, I always get a bit horny straight away.... Too bad it was a ladies' sauna that day. At least that's what we thought, but then three guys really did cum! Were we mistaken or were they? I don't know, but if they're already there, they might as well make their cocks available to us!
