You are a hit woman employed by the Mafia you have been sent to take down a witness who plans on testifying against your employer. As such he is in witness protection. You devise a setup and pretend that your car has broken down, you ask the witnesss if you can use his phone to call roadside assistance, which he does. The witness is sitting with you while you wait for the mechanics to arrive. While you are waiting you both chat and you offer him a beverage. He starts to feel groggy immediaetely after this and you begin seducing him in your tight dress and revealing those perfect tits revealing who you really are and how this is all part of your plan as instructed by your boss to seek revenge. You give him a blowjob and titjob getting him close to cumming, but not pushing him over the edge just yet. You ride him cowgirl again pushing him to the edge, you notice that he is getting close again holding him on edge... you offer to give him a tittyfuck to finish him off. You offer to use this special oil/lotion that will make the pleasure even more intense, you don't wait for a reply and start oiling up your tits. As you titty fuck you keep him on edge and let the pleasure build up again. You then explain to him that the lotion does amplifiy pleasure but it is also poisoning him the long you titty fuck him and fatal if he cums (you are immune having already taken an antidote) so he better hold on if he wants to survive and testify, you keep edging him telling him to hold on if he wants to make it through this. He can't hold it any longer and finishes on your tits with a massive cumshot dripping all over them. You then contact your employer and let them know the job is done they then tell you to go after the two detectives next.
