I never felt sexually attracted to my sister growing up. She is only 1 year older. When were young i have memories of her telling me to lay down, she would them unzip my pants, pull down my underwear and squeeze my penis/testicles. She called it playing doctor. I remember liking it back then but i realized when i think about these events in the present i get extremely aroused. I think this is because she kinda introduced me to sexual feelings in a way, so i associate them with her.
I cannot hide though that i still find her to be very sexually attractive (she has firm breasts and very full ass that makes makes me super hard). Also, the way she dresses makes it seem like she wants everyone to look and her breasts and notice her ass. For example, she will wear spandex all the time its pretty much like staring at her bare ass. You can see the color of her thong and if she doesnt wear any, you can literally see both of her vagina lips in the front.
As for her shirts, she always shows off as much of her boobs as she can without exposing her nipple. I feel like I see her nude breasts everyday just by the way she dresses. Sometimes she doesnt wear a bra with some of her tank tops and you can see her boobs move whenever she walks. Her nipples also usually show. I try not to look at them all the time but they are a natural C cup and very perky.

I can not help but be aroused. I obviously never wanted her to know that she turned me on and can make me hard as a rock in seconds.. she did find out though, which was the most embarrassing day of my life. I literally got a 100% full erection sitting next to her at the beach. The only choice i had was to tuck in in my wasteline.
There was really nothing i could do at that point but look down and pretend it wasnt happening. She did see it after a few mins, she joked and asked if i needed to apply more sunscreen. We both laughed just out of emberassment i guess. This was a very exciting experience for me, my dick was so hard and she saw it! I think she also assumed that she caused it since she was wearing a strapless top and she was leaning back where you could see a tiny bit of her nipples.

Many of my friends over the years have also been sexually attracted to my sister (they would talk and joke directly to me about her breasts, ass, pussy, etc all the time).. Hearing my friends talk about my sisters pussy was very exciting for me in a way. i would daydream about my friends fucking the shit our of her, which i really wanted to happen. It made me think of the way her tits would bounce when she gets fucked.

Two of my really good friends eneded up actually fucking my sister and i she didnt know that i knew. My friends were shocked that i wasnt mad but i just told them to fuck her as hard as possible. They both said the my sis was good at giving blowjobs. The fact that she put my frineds penises in her mouth makes me feel so happy. They even said that she licked thier balls.. Her lips are perfect for wrapping around cock and it gives me a boner thinking of her pussy getting fucked hard.. now i daydream all the time about my sister getting railed in the ass while her perky tits are bouncing and she is rubbing her clit. Her breasts are perfect, every time i see her in a bikini i get aroused immediatley and i have to push it down my erection.

My last sexual encounter happend with her a few years ago when we vacationed in miami. Me and her shared a bed and my parents shared the other. Earlier in the day i had caught a glimpse of her naked boob because a wave knocked her strapless top off one of her boobs.

Already horny from that, i wanted to cum that night. I waited for when i thought she was asleep. Then i pulled my patns down under the covers and started stroking me cock inches from my sis. She was facing away from me with her butt sticking out towards me. She was wearing royal blue sweats with no thong or panties. I remember the amazing feeling of pressing fully erect dick against her butt cheeks.

At this point i felt like she was asleep so i very lightly reached around from under her tshirt and exposed her titz which was easy because she wasnt wearing a bra. I almost came as soon is i tocuhed her tits because i was still keeping my dick lodged between her cheeks.

Then i got the great idea to just slide the sweats downa few inches. Ill never forget the feeling of my hard cock directly touching my sisters round exposed butt cheeks. I used the light on my phone to look at her naked ass. I saw her pussy too because of the way her butt was. I recall shoving my penis in between her cheeks which felt amazing. My balls were flush against her anus which felt awwsome. So i came on the very top of her crack and let my cum drip down her crack. Some did actually reach her asshole and her pussy.
