Totally normal straight behavior between two straight as an arrow regular dudes. Engaging in deep hot bareback sex blasting geysers of warm jiz all over each other whilst in deep embrace with ample open mouth kissing is simply a normal activity straight guys do together that is no different than playing a game of basketball or what have you.
I was SUPER STRAIGHT until i got drunk at a buddies house one night. Night was over, his bf and him got in a fight and he left. He jumped in the shower it was only me and him in the house. Well i pass out drunk and when i wake up hes touching me inside my shorts. I act asleep but my dick gets hard and gives me away. He whispers to me its ok you can play asleep. He got between my legs on the couch and pulled down my shorts a bit and put his head under ghe covers and started licking me up and down.
This scene is a fave but they are not straight. It's lacking apprehension of any kind and they have a connection. MAYBE they are great actors OR they could be bi but NOT straight.
