My cousin, well not really my cousin, Rhonda and her boyfriend were boarding at my house a few years back. I didn't mind since I was away and came home every second weekend. I used to admire Rhonda's full figured body. She had this ass that would jiggle like jelly and she always walked around with a nightgown on, showing off her perky tits and jiggly fully round ass.
My house walls are thin and one night I heard some soft moaning coming from Rhonda's room. Luckily, for me, I had found a pair of Rhonda's silk panties the night before and the scent of her pussy drove me to an instant whacking session. That was one of the few times I came so much that I actually amazed myself.
Anyway, I could tell Rhonda's pussy was getting rammed as I heard the bedsprings squeaking, slowly at first, then faster. I wasn't missing a beat while jerking. There in the very dim light, I imagined Rhonda's thick legs spread wide and her boyfriend's ass sinking balls deep into her pussy. I wished it was me sinking into that soft quicksand. I stroked to the time of Rhonda getting the full downward shaft in her. Then all three of us must of come at the same time because Rhonda cried out and her boyfriend let out a gasp. I had to use my hand to catch my cum before it hit the floor.
Needless to say, I am still a big fan of sound voyeurism, big asses like Rhonda's and of course masturbating. Let's keep it up!
