Bloodluxt - Two Girls

Three friends, two of them huge bodybuilders who claim to be the strongest guys in the place and who mock the third for being someone who was skinny and weak.
One night when they meet, one of the bodybuilders tells how he met a girl at the gym, whose muscles and strength rivaled his like no one else had before. Now the girl in question and a friend of hers arrive at the house where the three friends are gathered to spend a night that, without a doubt, they will never forget.
