But bob knew one thing no other man knew. After years of sheep fucking, his body had understood how much work his dick had to overcome, so it made a second dick that came out of his anus, and that's why he could continue sheep fucking with his reserve dick.
Finally, the sheep had enough of it. The ship poisoned their own vaginas (or anuses, depending on which way Bob went) with cyanide, and so the next time Bob tried to penetrate that area, the poison would deliver the death blow to his dangalang.
