Cinha Boa presents a raw, animalistic encounter as a new groom learns the ropes in a stable full of eager equines. The experienced stable hand, a rugged gay man, takes the initiate under his wing, teaching him the ways of pleasuring powerful beasts. The young groom hesitates at first, but his curiosity and desire grow as he watches the seasoned handler stroke and tease the massive, veined cocks of the stallions and mules.
