The Concierge

Beautiful blonde Regan works as an assistant concierge at a very upscale condo building in LA. In practice, that means she helps the rich people make appointments, carry stuff in and out, and waters their plants when they're away. Then one day she takes advantage of the penthouse being empty to have a shower in its luxurious bathroom. To her shock, the new tenant shows up. His name is Mark Stafford and he's a large, black, and very muscular, professional football player! And he's leaning against the bathroom counter, watching her, and asking why she's in his penthouse!Somehow she allows him to 'punish' her, rather than complain to her boss.
That turns into the most incredible, thrilling, scalding sex of her life, even if it does leave her bottom kind of sore. Stafford is soon teaching her how much he likes the game of domination and submission, and how much pleasure her mind and body can absorb from the hands and body of a skilled dominant. And then he hires her to work for him permanently - as his sex slave - so he can continue her lessons!
