I know many children don't want to see their parents divorce, but I was happy to see my Dad escape the clutches of my mother. She was a selfish woman, wasting my father's money on her so called friends. When the divorce was final, I chose to live with my father. My father dated different women but I never got to meet them. I asked questions about his dating, but he told me that he'd let me meet someone whenever he got into a serious relationship. Finally, one day he told me there was someone important he wanted me to meet. Her name was Tracy, and when I met her, I couldn't believe how gorgeous she was. She had bright and vivid red hair and a really cute face, but what I liked most of all were her disproportionately large breasts. She was fairly short - maybe five foot one - but stacked. Boy, was she stacked. I had never seen such large breasts in my life. I felt both proud and envious of my father. I was nineteen and in my senior year of high school, but had never been with a woman before.
The second time I met Tracy, my father mentioned that Tracy had a daughter my age, Viviana, and that he and Tracy would be married and Tracy and Viviana would live with us. Being a horny teenager, I wondered what Viviana looked like - how awesome would it be if she inherited her mother's breasts! I quickly found out that Viviana was quite the looker, as my Dad took the four of us to dinner. But Viviana only had one thing in common with her mother - her giant tits, not as large as her mother's but unusually large nonetheless. Tracy's first husband was Columbian and Viviana had soulful dark features and a sexy, husky voice. The idea of sharing my father's small condo with two large breasted women was more than I could bear. The week before their arrival, I must have had two or three wet dreams, imagining myself sucking their breasts and tit-fucking them, only to wake up in a pool of my own semen.
But the reality was not as good as my dreams! Viviana was stuck up and treated me like a child even though we were the same age. And when Tracy was around the house, she mostly wore baggy clothes that didn't show off her figure. But Tracy seemed to really love my Dad and make him happy and that made me glad. At night, I could hear their bed banging against the wall and moaning noises coming from their bedroom. "Well, at least someone is getting laid," my teenage soul bitterly expressed. I tried once to masturbate while listening to them, imagining Tracy's tits sloshing back and forth as I, not my Dad, pounded her, but it was just too creepy and my dick stayed limp.
I wasn't getting any action, but Viviana was getting laid a lot. My Dad and Stepmom were gone during the day, leaving Viviana and myself to our own devices. Viviana used this situation to basically become the biggest slut in our high school. She constantly had college boys over, with her door locked, and the boys were always buying her expensive gifts. One particularly productive afternoon, she had two different boys over; I could hear her gargling with mouthwash as she shuttled the boys in and out of her room. Bitterly envious of her callers, I was trying to listen through the wall into her room when I noticed a gap in the wooden walls. I realized I could see clearly into her bedroom through this gap. I know it was wrong to spy on my stepsister, but I justified to myself that if Viviana was getting laid daily, I should at least get some sexual pleasure.
While Viviana entertained boys, I would watch her and masturbate furiously. Viviana specialized in blowjobs and titfucking. Guys rarely got around to fucking her because her tongue and tits made them climax in a matter of minutes. At night I dreamed about fucking my step sister but it was just a dream - she saw me as a child even though we were both nineteen.
I'm a bit of a geek, and I began to keep a spreadsheet of her conquests, noting the sex acts she committed with them, the amount of time it took them to ejaculate and a qualitative assessment of the amount they ejaculated. I had recorded 28 different sexual partners and only two had actually fucked her pussy - the rest had climaxed merely from her blowjobs and titfucks. One guy had begged to fuck her ass, but she had refused.
One day I was reviewing the spreadsheet, running averages on the data, ranking the boys in terms of their staying power and volume of cum. Where I didn't know their name, I gave them a nickname, like "bad haircut." I know the idea of running statistics on my stepsister's sexual activity sounds ridiculous, but I have always had this weird analytical side to me. I must not have been paying attention, because Viviana came into the room behind me and before I knew what was happening, she saw my spreadsheet.
"You little pervert!" she screamed out. "You've been watching me, but how?"
Sheepishly, I showed her the gap in the wall. I figured I was busted and there was nothing to do but come clean. She peered through it and a smile came over her face. "I bet you jack off when you watch me," she accused me.
I shrugged. "Admit it," she ordered me, poking me in the chest and stepping forward to me. I fell back onto the desk chair. Her tits were inches from me and I wanted nothing more than to grab her breasts and suck.
"It's true," I told her. "I jack off to you all the time. I think you're really pretty. I'm sorry if that makes me seem like some kind of pervert." She laughed at me.
"I'll tell you what," she told me. "We'll play a game. If you can get me to orgasm, I'll have sex with you." She left and went to the kitchen, then led me into her bedroom and sprayed whip cream onto her clean shaven pussy. "Lick away," she commanded me. I didn't particularly like whip cream, but lick away I did. I hadn't had sex before, but I had read books about it and seen pornos and I tried to follow the instructions I had read and the things I had seen, fluttering my tongue near, but not on, her clit. I focused on her moaning and before long she was building to a crescendo. She grabbed my head as I continued to lick furiously and she orgasmed. I could feel her stomach muscles contracting against me and she yelled loudly, "Oh, God! Yes! Oh God! It's so good!" I felt so happy, knowing that I was about to have sex with my big-titted sister.
After her orgasm, she lay next to me panting and finally she turned to me. "Okay, it's your turn," she told me. I had removed my shirt and pants when just then we heard the door open and Tracy called out, "I'm home!"
"Quick, get in my closet," Viviana told me.
"Viviana, you have a visitor - James," Tracy called out. "He was arriving just as I was pulling up and he's here to study with you."
"Thanks, Mom," Viviana told her. "I'm studying up in my room." She hurriedly threw clothes on and I could hear James ascending the stairs. Viviana kicked my pants and shirt under her bed, so I remained in her closet in my underwear as James entered the room. James pulled the door to the room closed and took Viviana in his arms.
"I missed you, baby" he told her, lifting off her shirt and lifting her large breasts out of her bra. I felt angry - those should have been my hands on her breasts.
"I missed you, too" she told him as he began to fondle her breasts and suck on her nipples.
"Oh, I have to get my cock between your tits," he told Viviana. I gently pushed the closet door open slightly so I could better watch the two.
James stepped out of his pants and Viviana kneeled to the floor, taking his cock in her mouth. She swirled her tongue around his cock and then began to bob up and down on James's cock. He had a six inch cock and Viviana took it in to the hilt, making gurgling noises as her tongue lathered his cock. She paused and spread baby lotion on her cleavage and then wrapped her breasts around James's cock, arching her back. James grabbed ahold of her breasts, placing his hands over Viviana's and, pressing her breasts together, began to fuck her tits. Viviana was shaking from the force of James's thrusts. He began to moan and Viviana admonished him, "Try to be quiet, my Mom's home."
"Maybe she can join us," James joked. After mere minutes of his powerful thrusting, he began to climax. Ropes of ejaculate forcefully bounced off of Viviana's chin and settled back on her breasts. James continued to hold her breasts tightly and thrust his penis, which was slowly becoming flaccid. Finally, he came to rest and Viviana took him in her mouth, rolling her tongue around the head of his cock. James rubbed his ejaculate into Viviana's breasts. A dribble of ejaculate rolled over her lips as she let his cock fall from her mouth and she held James by the waist, pressing her breasts against him.
"We'd better get dressed," Viviana told him, handing him a towel and using a second towel to clean the fluids off her chest and chin. The two got dressed and after a few minutes of studying, James got up.
