Visiting Your Best Friend

When you're bored on a Saturday night, you spontaneously decide to visit your best friend Lea, who's at home alone with her new boyfriend Mike, planning a cozy evening together. There’s a lot of hugging and talking between the three of you, and later, some cuddling—until Lea and Mike start having sex right there on the couch with you sitting next to them. You can watch as they stroke each other, undress, and lie right beside you on the sofa. What are you wearing, and how will you react?
