FleshEater (1988)

Starts with four people chilling around a campfire in the woods — two white dudes with short hair, one blonde guy, and a slim girl with long wavy brown hair. They’re just sitting there, but the vibe is already flirty. Then it cuts to a basement where a redhead with long dark hair and a guy with short brown hair are getting into it. She goes straight for his dick, no teasing, just deep throat right away. Upstairs in the kitchen, two blondes — one with short hair, the other with long straight hair — are messing around near the counter. They’re kissing and touching, and one of them grabs a guitar like it’s part of the foreplay. Camera work is solid, lots of wide shots so you see everything, especially the oral part in the basement. No fancy editing, just raw stuff happening.
