A young Russian man died after betting two women that he could have non-stop sex with them both for twelve hours and winning the bet, a Russian daily reported Tuesday.

Sergey Tuganov, 28, dropped dead minutes after winning $4,300, the amount of the bet, Komsomolskaya Pravda reports.

The women told Moscow police that before starting the sex marathon, Tuganov swallowed a whole bottle of Viagra pills to ensure his victory.

“We got scared and called emergency services, but it was too late, there was nothing they could do,” said one of them, referred to as Alina.

Medics said the man most likely died because of the quantity of stimulating pills he had ingested.
