Betty's uniform-clad booty bounces as she eagerly sucks her patient's cock, her blonde hair bobbing up and down. She takes his thick shaft deep into her mouth, feeling it hit the back of her throat as she gags slightly. Betty's expert tongue swirls around his sensitive tip, making him moan in pleasure. She cups his heavy balls, massaging them gently as she picks up the pace, her tits pressing against his legs. Betty's eyes water as she struggles to take his entire length, but she's determined to make him cum. She can feel his cock pulsing, and she knows he's close. Betty pulls back, letting his hot, sticky cum coat her lips and chin, before licking it off seductively.
