Input: Text: yesterday i showed my very elderly grandfather how to operate the smart tv in our living room. all i taught him was how to switch from cable to netflix.

fast forward 4 hours. it's about midnight and i start to crave some ritz crackers. i walk downstairs and into the kitchen which sits behind the living room. as i'm grabbing the crackers i overhear intense panting. like something out of a horror film. out of genuine concern i walk out of the kitchen to investigate and see my grandfather watching porn on our 60 inch tv. and it wasn't just some soft x-art video, it was fucking hardcore brazzers shit.

you'd think that the immediate response would be to turn away as fast as possible and run the fuck back upstairs, but there was something inexplicably profound about witnessing such an old man furiously throw his hand at his dick. my mind was fucking boggled. he is so damn old i didn't think that kate upton and a shot of viagra to the heart could produce an ounce of chub. as soon as i got back into my right mind i quickly realized that there was no escape. he didn't notice me walking down the stairs but the way the couch is angled, he would surely see me go back up. so out of pure fear that he would find out that i caught him viciously masturbating to hardcore porn on the fucking living room tv, i sat behind the couch and waited for him to finish. the sound of that dick to hand friction is forever ingrained into my memory.

needless to say, i can't look him in the eyes anymore without also seeing his semi-erect penis.
