In the dimly lit, graffiti-covered alley behind the metro station, two strangers meet by chance. Their eyes meet, and without a word, they understand each other's intentions. One is a seasoned ass master, the other a curious, eager novice. The experienced one takes the lead, pushing the newbie against the wall and roughly groping their ass through their jeans. The novice moans softly, encouraging the ass master to continue. Clothes are shed, revealing smooth, toned bodies glistening with sweat. The ass master spreads the novice's cheeks, revealing their tight, pink hole. They spit on it, using their fingers to work it in, stretching and preparing it for what's to come. The novice gasps, their body tensing as the ass master's thick, hard cock pushes inside. The alley echoes with the sound of flesh slapping against flesh, their moans and grunts of pleasure.
