Caught But Didnt Stop

So i live in a house where my living room is out to my back garden, and there are alot of houses around. the house right behind my backyard, has a giant window from their bedroom, right to my yard. wich means they can see directly from their bedroom to my garden, and also my livingroom.
i often masterrbate in my living room because its my house and i dont really care if they can see, but today was different.
i have never actually seen them in their bedroom since they always has their Drabes infront of the window. i go to my living room and begin masterbating. after 5 minutes of wanking i noticed some movement from the window. it turns out the woman living there was ''making'' the bed, with only a bra on. normally i would have wanked even harder, but there was something different about this. i kept masterbating, but i stared at ''her''. i hoped she would look and see me. i think i have a little voyeur fetish but i dont know.
i have thought about having a threesome before, but that dosent count. But masterbating while somebody looks or the other way around turns me on alot.
should i do something about it. Keep masterbating, Ask her, Stop masterbating, stand naked with a sign that says: Wanna Fuck ?
