My sister was just as bad… We are now in this together.
I was 16, my sister some years younger (around 12).
We mostly ignored each other and existed in different circles.
One night, I was with my girlfriend, she was giving me one amazing blow job, and I had no idea my sister was watching from the dark stairwell.
My girlfriend pulled away just as I erupted cum all over her face and tits….she had some amazing tits, btw…
I had previously eaten her pussy, and she went into the bathroom to clean up.
While she was in there, I heard something from the stairwell; it was my sister, sneaking back down to her room.
I pulled my pants back on and decided not to do anything about it right now, but I’d talk to her later to see what her price was for her silence.
My girlfriend left, with a kiss and I went down to my room.
On my way down the hall, I noticed her door was slightly ajar, and my sister was on her bed, buck-ass naked.
She was rubbing her pussy, masturbating.
So I sat out in the hall, watching her in the dark.
When she finished, I entered my room.
A few days later, I didn’t have to work, so my parents wanted me to watch the kids.
The boys were watching some dumb show and I was sitting on the couch, next to my sister…
She was in a nightgown, and sat facing me, with her back on the arm of the chair…
She wasn’t wearing any underwear and was showing me her pussy.
I kept looking over, and when she’d notice, she’d spread her legs apart, showing me her cunt.
I was hard as a rock, and through my PJ bottoms, you could see it… A massive tent had formed, with nothing to hide it. So I just sat there, pretending not to notice my raging hard-on.
My sister, however, had noticed, and stretched out her leg and “touched” it with her foot…
I didn’t mind, really, and I leaned back, exposing the whole area to her, letting her “explore” my dick with her feet.
She changed positions after a minute, and sat next to me, like right up next to me, forcing me to put my arm around her.
She then slid her hand, ever so slowly, across my lap, and then up my shaft…
She wrapped her hand around it, through my PJs, and held on to it. I kind of pretended not to notice, but I slowly slid my hand across her lap, and between her legs, and she spread her legs to give me access…
So, there we were, her hand on my dick, my hand on her pussy.
The show was getting close to being over, and it would be bedtime.
So, with the end credits, I told the boys to go to bed, and my sister, too…
On my way down, her door was ajar again and she was sitting on her bed. As I started to walk by, she said something to me, so I pushed the door open and asked what she wanted.
She slid her nightgown up a bit, and then sat cross-legged, exposing her slit to me, so I went in and closed the door…
When I got close, I still had my raging hard-on, and it was poking out to her face. She was looking right at it and said that she’d seen me and my girlfriend the other night.
I asked what she had seen, and she’d seen everything.
She had watched me eat my girlfriend’s pussy, she’d watched me get a blow-job.
I said, “and”? Like “what do you want” and she said she liked me touching her earlier, and wanted to see my dick.
So I unbuttoned the fly in my PJs, and told her I’d only show her if she could keep it a secret…
She begged and promised she would, so I pulled my modest 6 inch long, 1 inch thick dick out from its hiding place… She stared at it and then asked if she could touch it…
I said ok, and she touched it with her fingers, rubbed it with her hands, and grabbed it, like she really had seen my girlfriend do…
I had to stop her, or I’d bury her in cum, so I said, “my turn”.
She stopped, stood up on her bed, and pulled off her nightgown. She stood there, nude, with her budding tits, and hairless slit.
I told her to lay on her back and spread her legs, and she did.
I then nelt down next to her bed and spread her pussy lips to expose her clit and cunt.
I asked if she has fingered herself, or put anything in her hole, and she said yes.
I started to rip my thumb on her nub, and she started to breath fast and shudder. It was totally awesome!
I rubbed her pussy, put the tip of my finger in her, and began probing her depths… I got my whole finger in, and figured she’d already broken her hymen.
So I fingered her with one hand, and played with her clit with the other.
It didn’t take very long at all and she climaxed.
Nothing at all like what my girlfriend did… My sister went completely ridged, trapping my finger inside her, and not breathing for almost half a minute!
When she started to move again, I extracted my now sopping wet finger. Which I then licked clean.
She laid there, and I stood up, and she sat up, I still had my now painful erection sticking out of my PJs…
She grabbed it and and I had to adjust her grip, it almost hurt, but I guided her to a fabulous hand job…
It was only about 5 strokes, and I unloaded an absolute bucket of cum onto my sister’s chest, bed, legs, and some hot her chin, and loads of it dribbled down and over her pussy.
She kept stroking, I kept cumming…
Until I could feel my balls run dry, which felt very weird, and had to stop her.
I told her to go wash up, because mom and dad would be home soon, and she shouldn’t be covered in cum when they get here.
She did, in the downstairs bathroom, and went to bed…
Whelp, now I’m a perv.
