Seth lay in bed indulging in his nightly jackoff sessions when he heard his twin sister come in from her date. This is kind of early, he thought to himself. Liz had been out with one of his friends, and he hoped that Bob hadn’t gotten out of hand. He brought his attention back to the video he was watching and was just starting to stroke his cock when Liz came in without knocking. They were almost seventeen and had been inseparable since birth. Even now, they hid very little from each other, or so they thought.
“Whatcha doin’? Liz asked as she plunked down next to him on his bed.
“The usual,” Seth showed her the porn video that was playing on his phone.
“Ooh, can I watch?”
“Me or the video?”
“You. Silly,” Liz said as she pulled his covers back so she could watch him jack off.
Liz had been joining her brother for his nightly jerk for the last month. During that time, she’d given him a hand, literally. She’d also helped herself to a sampling or two of her brother’s semen, which led to her letting him cun in her mouth.
“You just want to catch it in your mouth again, don’t you?”
“What?” Liz asked sarcastically. “I like the taste.”
“I thought you liked pussy, not cock.”
“It’s the taste of your cum that I like. Want me to do it for you?’ Liz asked as she pushed her brother’s hand away from his cock.
Liz stroked her brother’s schlong, coaxing a bead of precum to form on the tip of his cock for her to lick off. She licked the tip of her brother’s cock clean before covering it with her mouth. She swirled her tongue around his dick head.
“Do you want me to finger-bang you while you jack me off?” Seth asked.
“No, Bob already did that for me.”
Liz took Seth’s cock deep into her mouth a few times as she slobbered spit her brother’s cock.
“FFuck. Do you know how good that feels? I have to fight the urge to grab you by the ears and fuck your mouth every time you do that. I don’t know why you won’t just give me a blowjob? You’re getting really,” he said.
Liz started to stroke his cock while she sucked the tip with firm, steady suction. Her brother’s hips rocked rhythmically as the pleasurable sensations increased. Although her hand job felt good, it wasn’t progressing as quickly as I wanted. Seth tried a different tactic.
“I’ll lick your pussy if you suck it,” he asked.
“You don’t do it right.”
“Well, then, teach me how to do it the way you like it. Please. Then we can do each other,” he pleaded.
“You want me to stop, and you can do it yourself?”
“No. I don’t want you to stop. Can I at least play with your titties?
Liz huffed as she slid her top over her head and unhooked her bra to reveal her double D titties that defied gravity. She was perturbed by the attention that her breasts got her. Men ogled her constantly, and the boys. Well, the boys would be boys. They snap her bra in the halls at high school, and some even tried to cop a feel. The only person that she let play with them was her brother.
Liz placed one hand next to her brother’s head to balance herself as she dangled her tits in his face while she continued to stroke his cock. Seth would suck her nipples and squeeze her boobs to his face. She would know when he was ready to cum by the sound of his increasing moans. He would usually gasp and cry out that he was going to cum.
Liz let her brother suck her boobs for a few minutes, then went down on him and sucked his cock a few times before bringing her titties back to his eager mouth. After ten minutes or so, Seth announced that he was going to spew. Liz sucked his dick deep into her mouth and then out to the tip and back in deep. She felt Seth’s balls clench, and his cock swelled in her mouth as he began to squirt stream after stream of hot cum into her mouth. She cupped and gently squeezed his balls until he stopped cumming.
She lifted her head. “You owe me for that one,” she said as she wiped her lips. “I’ll teach you to eat pussy tomorrow while Mom and Dad are at work.”
Images of what tomorrow held filled Seth’s head, and he had trouble getting to sleep because of his throbbing cock. He had to rub out another orgasm before he could fall asleep.
Seth woke the next morning as hard as a rock but fought the urge to make himself cum in the hope of getting another blowjob from Liz. He got up and jumped in the shower before breakfast. Seth stepped under the steamy water and began to pee like a firehose.
He was still rock hard, even while relieving himself. Seth had to aim the stream toward the drain to keep the stream from splashing off of the walls. Still hard, he grabbed the soap to lather up his cock when he heard the door open and close. Liz had come in to pee.
They shared the hallway bathroom. The door had no lock, and there was an unwritten rule that if it was closed, you stayed out. Occasionally, there were emergencies, and one or the other had barged in on their sibling in a state of undress. Liz lifted her nightie and plunked down on the toilet to relieve her bladder.
She leaned over and pulled the curtain back a little. “Leave the water run, I’m going to… Oh my god! Is that all you do, jack off?”
“It won’t go down. I jacked off again last night and woke up like this. I even took a huge piss, and it’s still hard,” he said as he soaped himself.
“And you’re still hard?”
“Yup. The thought of licking your pussy kept me awake. Then I dreamt about it most of last night, too,” he told her as she slipped out of her clothes and stepped into the shower with her brother.
“What are you doing?”
“You’re not the only one who was up all night. I rubbed myself raw thinking about you eating me out,”
Liz dropped to her knees and washed her brother’s soapy cock. She washed his shaft and balls before she leaned out of the water stream to rinse his cock off so she could suck it. This was uncharacteristic of her, but after last night, a fire had been lit. Liz took his rigid shaft between her lips and swirled her tongue back and forth over the vein as she took him deeper.
.
“Jeez, Liz. Stop, I’m going to cum,” he tried to push her away.
“I want you to cum in my mouth, and then I’ll let you eat my cunt,”
“I was thinking that we could do it together,” Seth said, hoping that she’d agree.
“You mean like sixty-nine?” Liz chuckled. “You’ve got some learning to do before you’re ready to sixty-nine. Let me take care of you right now, and we’ll see how the day goes.”
Seth gently placed his hands on Liz’s head and followed her every movement as she sucked his schlong. It shocked him that she was taking him so deep. He began to undulate his hips, fucking her mouth as she sucked. His excitement got the better of him, and he grabbed her head firmly as he thrust his cock into her kisser. “Uh, Ahh fuck, Liz. I’m going to cum,” he said as he bucked his cock deep into her throat. Seth’s nuts spasmed as streams of spunk filled his sister’s mouth.
Liz grabbed her brother’s by the ass cheeks and held him to her face to keep him from forcing his cock down her throat. She gulped down his cock juice as quickly as he squirted. “Fuck, I’m beginning to like sucking cock,” she looked up at him with a smile.
Liz took the soap and started to lather her body and giggled when Seth slid his hands over her slippery breasts. She let him watch in awe at how she washed her hairless cunt. The surprised expression on his face when she slipped her soapy fingers into her cunt hole. Again, she giggled when her brother tried to slip his finger in, too.
After they had dried each other off, Liz led her brother to her room. She sat on the edge of her bed with her legs spread. “Kneel here so you can see,” she said as she tossed a pillow down for him to kneel on. Liz spread her pussy lips showing him around her vagina and telling him where she liked to be touched and licked.
“These are my lips. They are sensitive but not like my clit,” she pulled the top of her pussy slightly to expose the little man in the boat. “You start slowly by licking my lips, and when I start to hump my hips, that’s when you lick my clit. It just takes practice to get good at it. Give it a try.”
Seth leaned between her legs and kissed her pussy lips. He then slid his tongue along her labia a few times until Liz leaned back to enjoy what he was doing. Seth sucked her lips into his mouth and flicked them with his tongue. His sister inhaled deeply as she sank into the mattress. “Put your finger in me,” she moaned.
Liz jerked her hips upward when he slid his finger into her warm pussy hole. “Mmm. Now lick my clit,” she said as she started to play with her nipples. The added sensation of her nipple play quickly brought her to a climax. She placed one hand on her brother’s head to grab a handful of hair and mash his face into her cunt. “Shhh. Ahh fuck me, you’re making me cum so hard,” she hissed through her clenched teeth. Liz grabbed another handful of hair with her other hand as she humped away at his face.
Seth was proud of himself and continued to eat her until she squealed in ecstasy. By now, his rigid phallus was ready for another round of oral action. He crawled onto the bed and pulled her on top of him. She immediately sucked his cock into her mouth as she continued to hump her brother’s face.
Liz had countless orgasms as they sixty-nined for what seemed like an eternity. She wanted to try one more thing before her brother shot his load. Liz swung around and mounted her brother’s hips. She reached between her legs to guide his throbbing cock into her twat, and rode her brother’s cock like a woman possessed.
Seth winced in pain as his sister dug her fingernails into his chest when she buried his cock deep into her slit. He lifted his head to suck her nipples while his sister fucked him. His tongue swirled and flicked erect tit toppers.
Liz leaned forward and kissed her brother open-mouthed. Their tongues met in a torrid lustful dance as she thumped up and down on his cock. She took his face in her hand while she kissed him, breaking their kiss only to gasp in pleasure that she was receiving from her brother’s cock.
They began to moan in unison as they reached simultaneous orgasms. Liz threw her head back as she bucked wildly on Seth’s schlong while he thrust his cock as deep as he could into her snatch. He lost all control when he felt his sister’s pussy clamp down on his shaft. Stream after stream of cum poured into his sister’s slut hole until she collapsed on top of him.
“I think you fucked me straight, bro,” she giggled as she brought her lips back to his. “Well, maybe to the straighter side of Bi.”
