She’s laying out on the grass, sun on her back, no shirt on

It’s a sunny day, grass under them, a colorful towel spread out. One person is lying face down, back exposed, sun warming their skin. The other is on their stomach, crotch up near the first person’s butt. No shirts, no pants, just skin and sun. They’re not moving much, just kind of there, maybe getting ready to do something or just enjoying the heat. The vibe is chill, relaxed, no rush. You can see the grass blades, the towel’s stripes, the way the sun hits their skin. It’s not a big deal, just two people hanging out, sun on their backs, no clothes on, nothing fancy. Just real, quiet, and warm.
