This cop is in a bad mood. She had to chase this guy all over the place before she got him cuffed. She brings him into the interrogation room and un-cuffs him so she can search him for evidence. As she checks his pockets she thinks she feels something out of the ordinary. She takes off the perps pants to thoroughly check his clothing. She informs him that she needs a DNA sample for the DA. She puts on some exam gloves and begins the extraction process. She is very experienced in art of gathering sperm samples. She is better at it than the hookers she regularly busts. The perp has a nice cock so she decides to have a little fun while she is doing it. She pulls out her tits and rubs a little oil on them to speed up the extraction process. She climbs up and sits on the perp for better leverage. After a lot of stroking and some sucking the officer gets her sample. He's busted!
