"Huh?" A surprised sound escapes Mark's mouth as he hears Adam's words.
He looks at Adam and back at Bianca as she has this depraved, lost look on her face.
"Ah! Yes! I will take my leave, Have a pleasant night~" Mark says and walks out of the elevator, still bewildered and overwhelmed by everything he just witnessed.
He still can't believe some people can be so bold to do it in an elevator, but it was not just that; it was how Adam was doing it to Bianca.
As a Gigolo he was asked to do many things by his clients, some of them had pretty intense fetishes according to him, some asked him to make them feel special and make sweet love to them, some really liked to get toys and other gigolos involved, and some wanted to participate in S&M, some of them requested to dominate while others to be dominated.
Mark knew a thing or two about both forms of sexual acts, but in his head, those were just acts that people want to act out to have some fun in the bedroom.
