Big Sister in Big Trouble

My name is Jenna Zhao, a 21-year-old college student currently at home over summer break. I'm half Chinese, half white, the Chinese part coming from my mom. I never really knew my dad or his family. I mean, I met him but he and my mom broke up when he found out she was pregnant with me. She was only 18 and her parents didn't like that she got knocked up, either. So for most of my life, my mom was a single parent though my grandparents did support her when she needed it.

I assume the women in my dad's family must have big tits because I sure do! My boobs are way bigger than my mom's but she's still pretty hot. When I was little and we still lived with my grandparents, I didn't realize what was going on but I pieced together later that mom had no shortage of men in her life. I never really saw any of it but I knew she dated. And there were a few "dates" that were her just getting laid. I didn't meet any of her boyfriends until we got a place of our own. She still tried to hide stuff from me but a few times I would wake up early and catch her trying to sneak her current boyfriend out. That's how I met some of them. Once I got older, I realized that two things I inherited from my mother were her beauty and her overactive sex drive.

My boobs started getting big when I was just 14. They've always gotten me a lot of male attention. I admit, I enjoyed the attention and had more than a few boyfriends in high school. I only went all the way with two of them. But I have to admit, before I had actual sex I had oral sex. A lot. I just really liked it. That was as far as I let things go until when I was 16 the guy I was going out with, Steve, actually returned the favor. No one had done that before and it blew my mind. My head was so swimming with endorphins that when he said actual sex would feel even better, I couldn't see anything wrong with that logic. And there went my virginity. I dated him for a few months before I found out that he was telling everyone that we were fucking. I ended up dumping him. My senior year, I dated Richard and we had a pretty active sex life. But when I realized that I was going away for college and he wasn't, we decided to break up. We're on good terms, though. We just decided to not deal with the distance. Currently, I'm dating a really cute boy named Kevin. We've been together for over a year now and I'm fairly certain that he's not just with me because I have big tits and am great in bed.

When I was 14, my mom married James, a black businessman a few years older than her. She was his secretary and she fell for him. I kinda wonder if she was banging him before they decided to actually date. Hell, she probably did. Not that I blame her. He's rather handsome. He was also a widower and had an 11-year-old son, John. John was kind of geeky and we had nothing in common but I was still nice to him. I did notice that he stared at my breasts a LOT. But I was used to that and didn't think anything of it. Now, I'm 21, mom is 39, James is 41, and John is 18.

One day, I came home from the gym (hey, maintaining this body takes work!), and I saw my parents weren't home. I was going to take a shower but as I passed John's room, I heard something. "Oh god sis, you're so hot!" I also heard a strange noise. Curious, I opened the door. John was sitting at his desk with his back turned to the door and on his computer was a pic of me bending over. Now, I do like taking pics of myself that I post on Instagram. Okay, I'm a little conceited. I admit that. But I never took that pic! He must have taken that pic himself! And then I realized the sound I was hearing was him furiously jacking off!

"What the fuck are you doing?!"
