Two guys watch as one guy gets down on his knees

It's a grassy outdoor scene, maybe a field or backyard. One guy is on his knees, face down, wearing a red and black harness, with a yellow blanket spread under him. Two other guys, both naked, stand over him. One is looking down at him, hands near his crotch. The other is also looking down, hands near his crotch too. They’re both barefoot. The guy on his knees is wearing a red and black harness and has a black strap around his waist. The grass is green and there are trees in the background. It’s daytime. The mood is casual, maybe a little intense. The guys aren’t talking, just standing there. The guy on his knees is not moving much, just staying down. The two standing guys are just watching him. No one is touching him yet. The scene feels like it’s about to happen, but nothing’s started yet. The guys are all young, maybe late teens or early 20s. The guy on his knees has dark hair, the two standing guys have lighter hair. The guy on his knees is wearing a red and black harness and has a black strap around his waist.
