A Russian man collapsed and died after a 12-hour orgy.

Sergey Tuganov made a $4,300 bet with two women that he could last a 12 hour sex marathon with them both.

The mechanic swallowed dozens of Viagra pills in the course of the session to ensure he would win. However, minutes after the 12 hours were up and he was declared the victor, the 28-year-old had a heart attack, collapsed and died.

One of the women, who only gave her name as Alina, told Moscow police: “We called emergency services but it was too late, there was nothing they could do.”

Medics said he most likely died from the quantity of viagra he had ingested.
