Two people having sex on a mattress outside

Two people are having sex on a mattress that's laid out in the grass. The person on top is leaning over the other, who is lying on their back. The scene feels casual and spontaneous, like they just decided to do it right there. The lighting is natural, probably late afternoon or early evening. There’s no fancy setup — just the mattress and the grass around them. It’s not a big production, just two people getting it on outside. The vibe is relaxed, maybe a little messy, but real. No one’s watching, just them and the moment. You can tell they’re comfortable with each other, even if it’s not a planned event. The whole thing feels like a snapshot of a private, unplanned moment in someone’s day.
