Katerina Hartlova, a busty blonde, visits her gynecologist for a routine check-up, only to find herself in for a surprise. The nurse, eyeing Katerina's ample assets, suggests an enema to "loosen things up." Katerina, hesitant at first, agrees. The nurse, armed with a large-bore nozzle, inserts it into Katerina's tight ass, causing her to gasp. The warm water flows in, stretching her anal walls. Katerina's pussy begins to tingle, her nipples hardening. The doctor enters, his eyes widening at the sight of Katerina's big tits heaving with each breath. He takes over, sliding a speculum into her vagina, watching it open like a flower. Katerina, now aroused, rubs her clit, her body writhing as she orgasms, her asshole puckering around the nozzle.
