my younger sister 18f watched me cum and became curious.

​

before all of this happened me and my sister have had some run ins. she has accidentally walked in on me and i had seen a lot of her because she used to fall asleep in my room or in the living room and always wore skimpy clothes. but i digress.

i walked into my room one day and started watching tv and quickly put on some porn. i took out my dick and had a long session of stroking my dick.

i got up and cleaned myself off and when i come back in i heard a noise coming from the pile of blankets on my bed.

my little sister was planning on scaring me but instead she watched me playing with myself.

a couple days pass and just the fact that she seen that was getting to me, it honestly just made me turned on that she seen. then one night as we were watching a movie she brought up how she seen me looking at naked women and she watched me jerk off.

i asked her why she just watched instead of closing her eyes or letting me know she was there, and i jokingly asked if she liked it and she said it made her curios.

i asked her if she wanted to see what i was watching and she agreed. so we started watching porn together and i explained all of it to her. after awhile she kept looking down at my pants which hid a big bulge in it and i rested my hand on my crotch and slowly started playing with myself.

after awhile she started making noises and i realized she was playing with herself under the blanket. i put my arm around her and she moved in closer now starring at my crotch and i unzipped my pants and pulled them down. my dick was now in her face. she put her hand on it and didnt seem to know what to do so i helped wrap her hand around it and moved her hand for her for awhile.

she was smiling as so happy. she kissed it and again i helped her out and grabbed her head and held her mouth open and just slowly fucked her mouth while she was laying on my stomach.

i busted in her mouth and she was disgusted, she spat it all out and asked why i did that.

she got up to go to the bathroom and i could see her shorts were soaked.

she came back and fell asleep next to me. we have been having fun with each other for quite awhile now.
