The uncontrollable urge

I'd do it using my hot older sister's half-bras, bikinis, thong panties, anything she wore that I found sexy on her, which was everything. Anytime she saw or caught me, she'd watch and say "You better be thinking about ME", or "I love that I get you so hard for ME". Got to a point where I wouldn't even sneak or try to hide it, and would let her know, I have your tiny, black thong or bikini bottoms if you want them. She knew what I was doing with them, and, to her and her only. We were on the road one day and she halfway joked about "loving knowing she gets me to explode" and told me to not stop doing it.

I used to masturbate for my older sister she loved looking at my uncut cock and she would pull on my balls as I jacked off

I always liked for my mother to catch me jacking off, which was quite often, I think she kinda liked catching me..

Wow that is so awesome and interesting that you are fucking your sister and she is sucking your cock, so I am doing my sister for years now and baby I really love it and can't wait to fuck her hairy pussy tonight when she gets home from the bar. She is so horny and I love to fuck her ass she pushed her ass back on my cock and started screaming harder harder and push your cock deep into my ass and cum, wow that is making me horny and my cock is getting hard yeah baby

My sister and I masturbated in front of each other all the time growing up. She loved seeing me play with my cock and I loved seeing her finger herself and rub her clit

Wow that is how we first got started with just a little touching each other and we went on a feeling and kissing her tits and I love her hard nippels and I asked her if I could suck her tits and she said can I touch your dick and see how I would like it and we were both teenagers and drinking the parents booze and getting horny so we started to take our clothes off and then the parents came home so we stopped and we were both drunk. The next time our parents went out for dinner, yeah we looked at each other and took our clothes off and I said let's try a few things and we were sucking in a 69 position and I said I would love to push my cock in your pussy and she with a smile spread her legs open and said fuck me hard my cock was deep into her pussy and I was really fucking her when she said that she wanted me to fuck her ass and I bend her over and pushed my cock in her ass and she started to scream and moen and shake her ass back and forth on my cock and told me to pull out and cum in my mouth and I want to taste your cum and I pumped 2 loads down her throat and she swallowed all my cum and I told her that she was fucking great and that if she wanted we could fuck anytime the parents were out. She said that she wanted to practice sex a lot more and she loved my cock, that was many years ago and we have grown old now and we are both fucking 2 times a week now for the past 15 years and are going to keep fucking.
