Through the walls

I guess it is safe to say that Amy was not satisfied with our encounter on the porch either because it was five minutes of trying to drift of to sleep that I heard the unmistakably sounds of sex coming thorough the wall. Our bedroom back directly up against my brother's, with the headboard of our bed pushed against the same wall.

It wasn't the first time I'd heard the sounds of their late night passion, but on this particular night it seemed to be a little extra loud. I had a feeling Amy was putting on a show, knowing I would be able to hear everything.

"That's right baby, you like how my lips feel?" I heard her saying, then her words became garbled and I was pretty sure she had her mouth full.

"Oh fuck, Amy," my brother moaned.

I looked over at Kate, who was fast asleep. Not wanting to wake her, I slid my hand down inside my boxers and started playing with myself.

"You like that?" Amy asked. "I wish you would put it in me." Mumbled response. "I don't give a fuck what the doctor said, momma needs to get laid." More mumbles. "Well if you aren't gonna fuck it, you'd better eat it. You eat me and you can come in my mouth."

I could hear their bed moving as they changed position, and I could picture her getting on her back, legs spread.

"Oh fuck yes, I've been needing this," Amy moaned.

I thought about what we had just been doing on the porch and the fact that my brother was now just feet away eating her wet pussy. I couldn't take it any more. I needed to cum in a bad way, but should I wake up Kate or handle things myself?
