Alone and horny, a curious solo player explores the limits of his pleasure, delving into the taboo world of urethral sounding. With a massive, veiny cock in hand, he teases his piss slit, feeling the sensations intensify as he pushes a thick metal rod into his urethra. He groans in ecstasy, stroking his engorged member, before unleashing a torrent of cum, mixing his seed with his own piss in a depraved display of self-indulgence.
