Chapter 2

Mark came home around noon the next day. Ann's car was gone which was fine with Mark as he was not sure what he was going to say when he saw Ann. Was she going to be pissed? What would she think of him peeping and jacking off?

Mark was playing Play Station and did not hear Ann's car. She came into the house and came up behind the chair he was sitting in. "Did you enjoy the show?" were the first words that Mark heard.

He almost crapped himself he was so surprised by Ann. "Damn, you scared me to death. I didn't hear you come in."

She answered, "I thought you would never be surprised as you are so good at creeping around and spying on people."

Mark took a chance and answered her boldly, "You didn't seem to mind last night. You didn't ask me to leave did you?"

Ann bit her lip and looked down her cheeks glowing red with embarrassment. "No I didn't tell you to leave because it kind of, well kind of turned me on."

"What turned you on?" Mark asked.

Still looking at the floor Ann answered him, "Watching you jack off while Bill was fucking me. It turned me on to think that my body turns you on. I wanted you to stay and watch Bill fuck me. I wanted to watch your cock spurt."

Mark stood there for a moment looking at his sexy sister wondering how far she wanted to go. She seemed to be attracted to him; in a way he did not expect. Mark could feel his cock stiffen as he thought of his sister's naked body, her big tits and long, stiff nipples. He could see in his mind how good his cock would look sliding between her tits, his hands pulling her nipples as he tit fucked her.

Mark finally spoke, "So what do you want now?"

Ann answered him quickly, as if she had been thinking about this for a while, "What I really want is to watch you do it again, up close. I want to watch you suck yourself off again."

Mark was surprised, "You watched me masturbate?"

"Yeah, a couple of days ago, and I have been thinking about it ever since. It was so sexy, and I get wet whenever I think about you sucking your own cock. I wanted to be one of those girls in the pictures that you were jacking off to."

Mark thought about it for a moment and said, "I would be happy to jack off to your tits instead of porn, take off your shirt for me so I can see your tits. Let's go up to your bedroom and do it."

They quickly headed up the stairs to Ann's bedroom sitting across from each other on Ann's bed, and Ann said, "Pull it out and get started."

Mark just as quickly said, "Take off your shirt and show me your tits first."

Ann suddenly felt embarrassed; it was one thing to talk about it and another to actually do sexual things with your brother. Mark could sense her hesitation and he was not about to blow this chance he had dreamed of for so long so he pulled down his pants and underwear his partially erect cock springing to attention in front of her. He gripped his cock and stroked it a few times bringing himself to full erection in front of his sexy sister. His cock head leaked some pre-cum, and he rubbed the slick goo over the swelling head of his cock. He could see that Ann's nipples were hard and popped out erect through her shirt. He was so horny that he would have been happy to finish, but he did not want his chance to slip away.

"Now take off your shirt and give me some incentive to jack off for you," Mark said in a quiet voice.

Ann's doubts quickly faded away as she watched her brother slowly jerk off in front of her. His cock was hard, and his hand rubbed over the fat head that was already wet with his pre-cum. She pulled her thin t-shirt up and over her head and popped the back clasp on her bra spilling her big tits into his view.

Mark increased the speed of his jacking when Ann took off her shirt and bra. Her nipples looked even bigger up close, dark and thick on her big tits. Her areoles were crinkled wither her excitement and the cooler air of the room caused her nipples to stiffen.

Mark's cock felt hard and hot in his hand, and he could tell it would not take long to bring himself to orgasm. He deiced to push it a little further, "Squirt some lotion on your tits and rub and pull your nipples for me."

Ann grabbed the plastic bottle off of the bedside table and applied a liberal stream of lotion to her tits. She used both hands to rub her fat nipples, pulling and twisting the hard brown nubs as Mark continued to fist his boner. "Suck yourself for me," Ann instructed him.

Mark was ready to do it and he rolled his pelvis over his head bringing his cock in line with his mouth. Ann leaned over his head, her big tits right in his face, her eyes only inches from his cock. Mark lowered his pelvis and slipped the fat head of his cock into his mouth, his tongue rubbing the sensitive underside of his cock. Ann's nipples were only inches away from his face, and he could feel his balls tighten against his body as he drew closer to orgasm. His cock felt longer than normal, or he was more flexible today and he was able to suck the whole head into his mouth as he watched and pinch and tug her long, thick brown nipples.

Ann's eyes were fixed on his cock, and the only sound was their breathing and the slurping sound of his mouth working over his cock. Finally he moaned, "I'm cumming," and he began to masturbate his cock with his hand, ejaculating his load into his open mouth, the long white streams of cum hitting his mouth and face.

Ann did not say anything but was frozen watching her brother jack himself off. Her breathing was coming faster and Mark could tell that she was turned on by watching him. Her nipples were swollen and erect from all the twisting and tugging she had done to them, and he knew she must be ready for some action herself. The only question was what was the next step? He really wanted to fuck his big titted sister and wanted to make sure he did not turn her off, or make her shy away before he got his chance. He rolled his legs back flat on the bed.
