It all began when we were younger and we used to play dressup for fun, take showers together and share room until high school… We were just two close siblings but I guess I liked it at the end.
I’m J, 18 and my sister is A, 19 for the record. I’m a lonely guy quite by choice, I don’t like going out or meeting with people I just stay home all day, but she goes out quite a lot, just stays home a couple of days a week in summer and its for two hours max, she is really popular in high school although she doesn’t do well at all she is just fun to be around.
Now, I have always had this incestual fantasies with my mother or my sister but they’re mostly uncontrollable, on dreams or riding a bike so I can’t hold my cum from my underwears friction and that kind of situations. But what I’ve done multiple times is taking their clothes and wore it, feeling incredibly sexy and turned on, but the week before the incident I had another incident of my own, I came wearing my sisters yoga pants, used ones right from the washing machine before it was turned on, but my dad set it up and turned it on while I was using them so I had no choice but to return them later with my cum all over them, really staining the black lycra, to try to avoid getting caught which I thought I did. Back to the week of the incident, I was doing the usual saturday masturbation ritual, wear my sisters thong and yoga pants, or panties and pantyhose whatever she wore that day, and jerk off, this time trying to avoid cumming in them again. Today she wore a grey CK thong and the same yoga pants as I came in last week, I found it so hot that she wore them, but when I was wearing the pack I confirmed suspicions I had while holding them; some parts were a bit wet. The thong felt wet on my crotch and balls, and the yoga pants all over my butt, but it just felt wet I couldn’t see nothing on them so I began humping my sisters pillow while looking at incest porn and smelling her juices. It was going just like another day until I hear a throat clearing, and I turn back to see my sister holding her phone to me:
-So I was right, you were stealing my clothes.
-What? You knew about it? Listen I can ex-
-Shut up dumbass and listen to me, I’m not really mad I already took revenge on you.
-What do you mean, you took pictures? What do you want me to do?
-Ooh yeah I took pictures, but also J honey can you tell me what is all over you hard willy and your bum?
-Y-your… juices…?
-You wish honey, I was at my boyfriends earlier and we played a lot, he came on my thong, on my butt… While wearing what you are wearing right now, isn’t it hot? And with the flash from my phone you can see all your ass is covered in shiny cum, so unless you return them right now and promise you will never steal my clothes again I won’t release these.
I took a look to the pictures and my thoughts started racing. My sister caught me in her clothes humping her pillow, she already knew for some time apparently, she had her boyfriend cum all over her stuff so I wore it and felt disgusted although it made me weak in my knees to be honest, and she was blackmailing me. I just couldn’t hold it. I came right there, some running down my shaft and some spraying through the yoga pants to her. I had to grab her shoulders to not fall, now my knees were trembling. I took a look up, and she was just smiling in awe, but not really laughing at me.
-Little brother, we are going to have some fun together and no one will know, unless you behave bad. Is that okay?
-Y-yes A, it is…
