Jerking It While My Sister In Law Is Masturbating In The Shower

my sister in law lives with us. recently i found that sometimes she showers early in the morning and i overheard, what can only be described as pussy slapping coming from her bathroom.

this happened a couple of times, and each time i got really hard hearing it. finally one morning i couldn’t take it any more and i stood outside her door and listened as she got in the shower. she definitely takes way longer during one of these sessions vs a normal shower she takes.

i could tell that she didnt have the water spraying on her, but i could hear her making some soft moaning, then she just went at it full on slapping, im not sure if shes using a dildo or her fingers but she is really giving that pussy a beating.

she would go for a good few slaps, then stop. then she would start again.

each time she did, i was stroking my cock like crazy

dry stroking was fine but i was really feeling nasty so i just spit on my hand for lube and went at it again. trying not to cum each time, finally i couldn’t hold it and ran into the kitchen to release my load into the sink. it shot so hard and felt so good.

after that happened, i couldn’t get the thought out of my mind. when she leaves the house i go into her panties drawer and grab a pair of panties, then i stroke my cock until i get a little pre-cum and soak the pussy area, rub it in good.

i get some of her dirty panties and go into her bathroom, wrap them around my cock and jerk off until i cum. i always rub a little cum on them before i return them to her dirty clothes basket.

i dont want her to find out, i just want to cum on her shit and think about it. im fucked up i know, but whatever.
