Caught my 18 y.o sister masturbating

Note : This story is completely fictional!

I'm a 20 years old guy and I have to say that my sister Jen is one Hell of a hottie. She's 18 years old but has a great body, a perfect ass, a cute face and a shaved pussy. Her bra size is 34 C and her tits are perfect not too big not too small. I have a pretty good relationship with my sister, I watch out for her and make sure she's always ok.

Anyways, 2 weeks ago, I arrived from work earlier and felt like listening to some good old Metallica songs but the CD is in my sister's room. Since she's not there, I decided to enter to get the CD. After 10 minutes of looking around, I found what I was looking for but I also saw porn mags under her bed. Intrigued, I looked at the magazines for a while. Time goes by and suddenly I hear the entrance door opening. At 4:00 p.m. it can only be my sister arriving from school since our parents only arrive at 6:30 p.m.

I stress out, not knowing what to do (because if my sister catches me in her room when she's not there, there might be heel to pay) I throw the magazine back under her bed and hide in her closet. She arrives in her room (I'm sweating bullets) takes off her coat puts her purse down and puts on a CD. I can still see whats going on through the closet door. Jen was wearing a white shirt and a black skirt. She also had her long black boots that gave her a slutty appearance. She untied her hair and sat down on her bed. I was on the verge of dying because of how hot it was in her closet and because I didn't want to get caught. What i saw next, was absolute beauty, the best thing I saw in my life. Now remember when I said my sister was one Hell of a hottie... well here goes.

She pulls out a porn magazine from under her bed and starts looking at it. She starts touching herself, rubbing her arms and her legs. She unzipped her long boots and started caressing her feet. She takes off her shirt to reveal a beautiful black bra under before taking off her skirt. My 18 years old sister, there in front of me, in her bra and panties looking like a freaking godess. She starts rubbing her pussy and her tits and finally takes her bra and panties off. She had the best looking body ever and she just continues to finger herself in front of me. My dick is hard like stone and all I want to do is jerk off but since the closet is way to small for me to masturbate, I have to endure watching my 18 y.o sister masturbating without having the chance to masturbate to such a nice view.

She pulls out a vibrator from her drawer and just sticks it in her pussy and continues masturbating. She sticks her toy in her pussy and then sucks on it with her mouth and takes care on licking all of her pussy juice off the vibrator. She likes it so much that she sticks a couple of fingers in her pussy and licks them after. Then she turns around with her back presented to me and she bends over and sticks her vibrator in her ass and continues pleasuring herself, she moans and moans and sticks her fingers up her ass and I'm about to get out the closet cause I can't take it anymore and suddenly...

The phone rings, jen leaves her room to answer and hey !! here's my chance to leave. I get out the closet, (at this point my cock is 10 inches long after what I saw) I'm almost out of her room and she comes right back in still talking to her friend on the phone. She puts the phone down (here I am looking really intelligent in her room while my boner is 10 inches long) and asks me what I'm doing in her room (she's pissed). I don't know what to say so she asks me if I saw her session of pleasure and i still don't answer at this point she knows I've seen EVERYTHING! and instead of beating the living daylights out of me she smiled. She told me it actually turned her on that I was watching(by the way she is still naked). She grabbed my cock and started rubbing it (now I'm turned on but it's still my sister) I ask her what she's doing and answers that our parents only arrive in 2 hours and we still had time for a little fun.

She took off my pants and my shirt and started sucking my huge cock. Her mouth felt like heaven. She pushed me on her bed and just continued sucking me for the next 15 minutes. She then told me that she wanted to masturbate so I could watch her every move. So there I was, looking at my sis with a vibrator in her pussy and 3 fingers in her ass. When I was tired of looking, I pulled the vibrator out of her and licked her vagina that tasted so sweet. Sticking my fingers up her ass and sucking her clit. I fucked my sister into sheer extasy fucking her pussy with my huge dick. I even fucked her ass. In the end, I cummed all over her awesome boobs and she licked every trace of sperm on her body.

So now, even if I have a girlfriend and she has a boyfriend, we know the best SEX! is with each other and we still fuck our brains out from time to time.
