Foursome in the Anatomy Laboratory

Studying together becomes more fruitful when each student contributes their own contribution and teaching materials, but they choose the wrong topic: a large, stylized female vagina cannot mate with an equine phallus, so the girls apply the empirical method of personal experimentation, stripping naked and taking turns fucking the big cock of the only male available, while they lick each other’s pussies and masturbate with dildos.
