All the office girls fancy salesman Mark and today Lissa is going to seduce him. She drags him into the stairwell telling him how sexy she thinks he is and rubbing the front of his trousers to get him horny. She then strips him naked right there and then before dropping to her knees and giving him a blowjob. Unknown to Mark she has arranged for the other girls to watch it all and they sneak in and watch from above his head taking photos and videos of him naked on their phones. As Lissa wanks and sucks his cock he loses control and cums all over her face making the watching girls cry out in excitement. Mark turns round in horror and is not happy they have naked photos of him but the girls run off with their blackmail material safe for whenever they need it.
