When Kenzie Reeves shows up to Markus Dupree's pharmacy to pick up her Libido Limiter medication, a delay in processing her order has Kenzie fighting against her own overwhelming desire to masturbate because she has such an appetite for cock. After trying to aggressively seduce a fellow store patron, Kenzie starts to rub her pussy with whatever is on hand - literally. After Kenzie busts a -pressure monitor with a leg-shaking orgasm, Markus realizes that the best way to manage Kenzie's gargantuan libido is the direct application of his hard cock in her tight ass for some rough and raunchy anal action. Who says doctors should have all the fun in porn?
