One of the "Fear Factor" contestants who drank donkey semen is finally breaking her silence -- claiming her spunk-chugging experience "was the hardest 15 minutes of my life."

Twins Brynne and Claire Odioso -- who competed on the episode -- called in to the Cowhead Show in Tampa today, describing the donkey splooge-o-rama in graphic detail.

According to Brynne, the twins got to choose who downed the semen and who drank the donkey urine -- Claire pulled the short straw.

According to Claire, producers left the semen sitting out all day in the hot sun -- and by the time she got to drinking it, it was boiling hot ... which made the smell unbearable.

Claire said it was extremely bitter going down ... "with hints of hay" -- and she vomited several times before successfully drinking the entire glass.

As for how the donkey stuff compares to the human variety -- Claire added, "It's a lot thicker."

Not that she knows from experience or anything.
