Professor Davis, a stern-looking middle-aged man, stands at the front of the classroom, his monotone voice droning on about the Roman Empire. Liz and Demi, two identical twins with long blonde hair and big, round tits, sit in the front row, their eyes glazing over as they listen to the professor's lecture. But as the minutes tick by, their minds begin to wander, their thoughts turning to more carnal pleasures. They exchange a glance, then a smile, and before long, their hands are wandering, their bodies pressing together. They strip off their tops, their tits bouncing free, and begin to suck and lick each other, their moans filling the classroom. Oliver, seemingly oblivious, continues his lecture, but as the girls move to the floor, spreading their legs to reveal their wet, hungry pussies, even he can't help but steal a glance.
