Seen your son cumming?

I walked in on my son fucking his sister doggie style she could not see me but he did and contiude to fuck her till he pulled out and blow his load over her ass looked at me and smiled I just nodded and smiled back

Yes. Behind out house is a structure. Im not sure what to call it. Its used for storage and projects. Its open in front like a garage. Its a big and has a couple of small rooms and a restroom. Its really big. We even have parties or bbqs back there. Anyways I figured out my son used to have a small area he mastrubated in. I accidentally heard him. Later I tried to see if there was any way I could spy on him and I found two different places where I would have good views, if he was facing the right way. Now if I know he's going back there I will follow so I can watch. Yes something is wrong with me, but watching him gets me very horny. I am to nervous to rub my pussy while I spy on him jerking off, but yes, to answer your question, yes.

Hard to see when it was in me, but certainly felt it.

Yes I have. He has a big cock, igger than mine

No, but I have felt him hard
