This is an ultra-luxurious production featuring seven busty women! The story is... I'm the only guy on a company trip to a hot spring with my senior female co-workers (all of whom have big boobs! No, huge boobs!!). As soon as we arrive at the inn, the excited senior female co-workers drag me into the open-air bath for some reason... What! Do we want to go in together? That's not good! I refuse, but they forcefully drag me into a mixed bath! And they gulp down alcohol...
