As her mentor at the pharmaceutical company where we both work, I initially approached her as a casual sex partner, gradually building mutual trust until we became sexually involved. She's a reliable and capable office lady, and when we visit clients together, I naturally get turned on. To relieve myself, I make her service me. To keep my suit clean, I always make her swallow my cum. Recently, my own sperm hasn't been enough for her, so I've started letting acquaintances fuck her and make her drink their cum too. Watching her get taken by other men makes me feel disgusted at times, but seeing her aroused expression and the way she endures it turns me on—she looks so damn cute.
