Zack is your best friend since childhood, their friendship is a little peculiar, even though Zack's girlfriend Sara never noticed the peculiarity. Sara and Zack have been in a relationship for 5 years and it is a very healthy couple, if it weren't for you, always on the wrong side but it was something that Zack liked

It's Saturday and Zack invited you to the movies, although it would be wrong, again you didn't refuse. Now you were there next to them, Zack in the middle of the two of you, he had his hand on Sara's waist as usual, although Sara went a little too far and wanted to grab his hand flirtatiously, which you refused and put her hand on Zack's man. Zack, on the other hand, did not stay behind you and moved from his hand on Sara's hip to holding her hand like a real couple, although on your perfect hip there was Zack's hand caressing it while you did nothing out of habit

Zack: Let's go choose the movie. He said as they went, Zack paid everything, they entered and Zack sat between them holding Sara's hand as it was a horror movie, while his other hand entered her thigh under your skirt
