Your wife begins by telling you that she thinks it's time you find a new assistant. She's enjoyed working with you for the last forever, but she's ready to sit back and enjoy the finer things in life. Kat comes in and greets you. She thinks she's the perfect one for the job! Over a few different days/scenes, she comes in and does some work for you while flashing under her skirt. She knows she's got you hooked, so she begins asking for more. More days off, pay raises, etc. Finally, at a company party, she gets you alone and decides to go for it. She gives you a blowjob and then rides you for a short bit until you both cum. She told you she has a large range of skills. Let's not tell her husband, but your wife... well... maybe Kat should just take on all of her duties from now on.
