Both twins cleaned up after dinner then went to the living room and turned on the TV. Slater wanted to watch the news, but Karen wanted to watch some game show. They decided on a documentary about polar bears. Neither of them really paid attention to the TV once Karen started to kiss Slater. They sat on the couch, making out and feeling each other up.
Karen was soon groaning with pleasure as Slater slowly moved his fingers in and out of her pussy. She kissed him passionately, barely able to keep her lips on his as she came and came.
"Oh fuck!"
Karen screamed as her orgasm shot through her body just barely taking her lips from his. Then her convulsions caused her to arch her back, her head now in Slater's lap. Slater watched his sister convulse with pleasure as he kept fucking her with his fingers.
"God you look so beautiful when you cum," Slater whispered.
Karen convulsed again at his words. She was breathing hard, her chest falling and rising quickly. Her eyes were staring at her brother glistening with tears. Her mouth was frozen in an oh shape while her hips bucked up and down as Slater shoved his fingers into her body.
"Oh god, oh god, oh god," Karen finally yelled as she came again.
Slater slowly removed his fingers from his sister's pussy. They were slick with her juices. He shoved them into his mouth and sucked them clean. Karen sighed as she watched her brother suck her fluids from his fingers. She was so turned on just by his doing that, she had a small orgasm just watching him.
Slater slipped out from underneath Karen, standing over her. His cock was sticking straight up, his balls were tight to his body. Karen smiled as she swung her legs over the edge so she was now sitting with Slater's cock bouncing in front of her. She smiled up at him, then slipped her lips over the head of his beautiful cock. Slater groaned as his sister's tongue licked the underside of his cock. He was on the verge of coming.
"Oh shit," he yelled. "I'm going to come."
Karen started to suck harder. When the first spurt of Slater's cum hit the back of her throat, she shook with orgasm. She swallowed and swallowed, as rope after rope of semen splashed in her mouth. She groaned each time. Her brother tasted wonderful. She kept his cock in her mouth, even as it started to soften.
"Oh my god, you're good at the Karen," Slater said softly.
Karen smiled pulling his soft cock from her mouth.
"God, I love you," she said stroking him gently.
"I love you, too," Slater said groaning.
Karen kept stroking her brother's cock until it was hard again. She smiled up and him, laying back she spread her legs. Slater looked surprised but slipped between her legs. His hard cock got even harder. He looked into Karen's eyes.
"Are you sure? Once we cross this line, there is no coming back. We will be labeled as having committed incest."
"I'm sure, Slater. I'm so sure I want you inside my body."
"Are you on the pill?" Slater asked.
"Yes, mom made sure I was in my sophomore year. She didn't want me to get pregnant even though I stayed a virgin until the end of my junior year."
"Good."
Slater lined his cock up with his sister's vagina. He slowly pressed into her body.
"Oh fuck!" she screamed.
"Am I hurting you?" Slater asked.
"A little, but it feels so good to be stretched out. Keep going sweetie," Karen replied.
Slater pushed slow and easy into his beautiful sister. She didn't scream anymore, just moaned as each inch of his cock slipped into her pussy. Then Slater was pressing against her cervix. She grunted a little. He pulled back a little and she smiled up at him.
"That's good. Oh god, you feel so good inside me," Karen growled.
"You are so hot," Slater croaked.
Karen closed her eyes and pressed her head back into the cushion under her. She moaned her body shaking with a small orgasm.
"Fuck me brother, fuck me hard," Karen said softly.
Slater withdrew his cock until just the head was inside his sister's pussy.
"Slam it into me," Karen yelled.
Slater slammed into his sister's pussy. Fast and hard. He started to pound into her as fast and as hard as he could. Karen started to scream with the first slam into her body. Slater kept up his pace. He was young and powerful. His sister moaned and groaned as he did. Karen was now just looking up at Slater with amazement. She had never felt something so good. Even when she started to use a vibrator on herself, it wasn't as good as Slater's cock.
"Oh my fucking god," Karen screamed.
She was coming and coming. A never-ending stream of orgasms as her brother's cock pounded her into the cushions. Just thinking about what her brother and she were doing was making her cum. What Slater's cock was doing to her was fantastic. She was on the verge of passing out when the blackness of unconsciousness overwhelmed her.
Looking down at his sister, Slater saw here just pass out. He just kept fucking her, he was almost there, again. Karen started to come back from the darkness when Slater slammed into her one last time and roared his orgasm to the room. Spurt after spurt of her brother's semen filled her pussy. She felt every splash of his seed in her belly. Karen wrapped her arms around Slater holding onto him tightly. She pressed her lips to his as they both came. Their tongues fought for dominance. She let Slater win.
They kissed for a long time. Then Slater's cock, now soft, slipped from Karen's pussy. His cum splashed from her onto the cushion. She started to giggle. Slater pulled away and looked down at her as her giggle became a full-blown laugh.
"What?" Slater asked.
"I just wonder how many times mom and dad lay here and dad's cum splashed out of mom onto these cushions after we went to bed?"
"Not something I want to dwell on," Slater said.
"Then why is your cock getting hard? I can feel it poking me."
