I arrive at the European Exchange Student dorm late one Saturday night. All of the other girls are out on the town on dates or at the movies together. Only Russian sisters Di and Margarita have stayed behind this night to get my help learning English. They look similar, with long dark hair and thin frames. Their tits are medium sized with nipples that poke out of their t-shirts. Their butts look so cute in their matching cut-off blue jean shorts. We move into their shared bedroom and I take a seat at one of their desks, while the girls recline on their shared bed. No need for a textbook to teach them the words I want them to know most. So I begin . . . .
