Your wife's kidnappers sent you this photo
They just kidnapped your wife and are demanding a ransom. But to show you that they really have it, they just sent you some photos of her, practically naked, tied and gagged. These photos leave no ambiguity about their intentions if the ransom is not delivered quickly. Your poor wife, usually so modest and prudish, risks discovering sexual practices that she has always refused you... So why rush to pay, perhaps you will soon receive other, more horny photos...
