<human>: This actually happened a month ago.
My ex and I have been on and off for quite a while now. The other day we were at my friend's house when she fell asleep. So my ex and I thought we would go into the guest bedroom and start to... Ya know, do stuff. 

So we get into the bedroom and it is in pristine condition... The bed has a dozen different frilly pillows on it and the bed is very well made.... So we start kissing on the bed. And he is on top of me kissing me when all of the sudden right underneath my head I hear, 

"Ummmm.... Guys?"

My ex jumps off of me and I throw myself off of the heap of pillows just as my friend's younger brother bolts out from under the pillows... Stands by the bed for a second looking at us both and then runs up stairs.
My ex and I awkwardly stare at each other with our jaws dropped for a moment and then we go out into the living room.

Can you condense the text into three sentences or less?
<bot>: My ex and I were making out on a bed with pillows. A little boy chose under the pillows as his hiding spot in hide-and-go-seek.
