<human>: Last night, I decided to stay in my room and let the night drone on while playing a mobile game. Throwaway for safety.

Just a bit of context: our home's first floor is basically a small studio, with a dormer-like, attic-like space (is it accurate to call it a loft? IDK) as a second floor where I (and my younger sister who's in college) sleep.

As it was getting quite late, my father shut off all the lights and went to bed. At around maybe 1 AM, I heard sounds of people moving about on the bed downstairs. Initial thought: well, maybe they couldn't find that snug position/spot.

A few minutes later, the movements got a little more intense. There were the occasional gasps and moans, too. 

Then it dawned on me... *my parents were fucking.*

I had to cover my ears with a huge-ass pillow just to tune them out. At first muffling the sound seemed to work, but not when the bed frame started squeaking from their movements and when they started moaning. 

I don't know how long that lasted, but I know for a fact that I won't sleep late for a few weeks.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Stayed up late playing a mobile game, heard the parents' entire fuck session, had to cover ears with a pillow 'til the deed was done.
