A sister’s personal time

Grace was sitting on the couch facing towards the television which was on. That would have been fine for Marcus any other time if it wasn’t for a few things. One the television was currently showing some random porn video but there wasn’t any sound playing. Two, Grace was nearly naked with her bikini top missing, her shorts pulled down just below her large fat ass and wearing some wireless headphones explaining the lack of noise. And three both of Grace’s hands were in between her legs clearly masturbating to said porn video.

Marcus felt his cock start to harden in his jeans from the sight alone making an obvious bulge. Just by looking at her it seemed that Grace has been masturbating for a long time due to the amount of sweat covering her body giving it a nice glow from the lights. No matter how much Marcus wanted to turn around, walk away, and act like he had returned home he couldn’t because his feet felt like they had metal rods going through his them rooting him to the spot.

Looking at Grace his eyes wonder over her beautiful and sexy body. Marcus watched the way her small tits would rise and fall from her heavy breathing. The way that her legs would move and flex around her hands as they moved in between her legs. How Grace would lick her own lips wetting them giving a nice shine to them. And hearing the sexy moans that escape from her mouth every now and then was just a bonus for Marcus at the moment.

After a short moment Grace started to move and for a second Marcus thought that he was about to be noticed. But it seemed she didn’t because all that she did was lift up her legs onto the couch after letting her shorts fall down to the floor and spread them to give herself more room to play with her pussy. With the extra room Grace was able to push her fingers deeper into her pussy and also to move her hips to add to the pleasurable sensation.

Soon it seemed that Grace was about to cum when she started to pick up more speed. Marcus could hear how wet Grace is as she tried to get her fingers deeper and deeper within her pussy which no doubt was creating a stain on the couch. Removing one of her hands she brought it to one of her breasts and started to knead them and lightly played with her nipples.

Suddenly throwing her head back Grace let out a loud moan as her body started to shake and flex from cumming. Watching her cum Marcus felt almost hypnotized at the sight. He was looking at a side of Grace that he doubts many has possibly seen or experienced. A moment later after riding out her orgasm Grace started to shift again but this time she started to stand up after removing the headphones off her head. Panic went through him but before he could do anything Grace finally noticed him standing there.
