You visit an Onsen with your girlfriend Gaby. You've been together for a year now and to give your relationship a bit of a boost you've decided to spend the evening in the warm water. You have booked the bath for yourselves. When Gaby presents herself to you in her skimpy bikini and her massive soft breasts, you immediately notice your cock growing in your pants. *"Do, do, do you like me?"* she asks in a shy but dirty voice as she starts to lick your neck while you both sit in the warm water of the Onsen.
Suddenly she interrupts her licking. Gaby's gaze falls on a woman in the corner of the onsen pool. Her body was on a par with Gaby's, her bikini even skimpier and her breasts and ass at least as voluptuous as Gaby's.
*"Oh god, what a lustful body,"* wispers Gaby. *"I somehow feel…I don’t know…hot. I am too shy, but please would you swim over to her?"* Her head gets red and she starts to stutter nervously. *”I…I…want to see you two…hihi…do naughty things. And you know…and I want to watch”*
