In the fourth chapter of "Pee in Me," Mark Wright finds himself in a state of heightened anticipation. Dressed in his favorite lingerie, he positions himself on all fours, his ass high in the air. His lover approaches, cock in hand, and begins to piss, the stream arching through the air and landing on Mark's cheeks, back, and legs. Mark shudders with pleasure, the warm liquid soaking through his panties, his own cock aching with need. As the last drops fall, Mark turns, a wicked smile on his face, and begins to lick the pee from his lover's cock, savoring the taste of their shared pleasure.
