In their shared bedroom, the two innocent teens blush as they whisper their curiosity about the taboo. The older sister, bold yet inexperienced, suggests they explore together. They tentatively touch each other, their breaths quickening, when a knock at the door reveals a mysterious man. He listens, then offers to initiate them. With a wicked grin, he spreads their legs, first tasting their young pussies, then sliding his thick cock into each, back and forth, as they moan and cling to each other in their first DP.
