Too late to stop

When Kostya's gf agreed to sleep with his mate to earn the money for a river excursion he thought he'd be able to take it not knowing that there's nothing more terrible for a stud than witnessing his dearest one smooch another fellow and stretch her vag to take his pecker. He wished to stop it, but it was too late and he had to just sit there holding her arm and see this insane man poke the enjoy of his life with that thick hard-on.
