Jonathan jerked to attention when he heard the creaking of his door. He stared into the darkness and saw a silhouette of a person. His heart raced. This was not happening, he told himself. Was this a home invasion? He picked up a book from the nightstand and almost wanted to throw it to the silhouette until he heard his sister telling him to stop.

“God. Rachel. What time is it?” he turned to his bed and groaned.

“Shhh…not so loud. Mom and dad’s sleeping.” she hissed.

“It’s three in the morning. I’ve class later.” he groaned as he looked at his phone for the time.

“I know, I know. I’m sorry.” she whispered and sat on his bed.

“What do you want?” He asked with his arm over his eyes.

“Do you remember the time when mom and dad went out last Saturday?”

“Yeah?” Jonathan removed his arm and sat up. He remembered alright. How could he forget about that; the day his sister gave him a blowjob.

“I’ve been thinking about it all night and can’t sleep.” she protested.

“What do you mean?” Jonathan grimaced. He recalled they both agreed that it was consensual. Was she regretting about it now?

“I’ve been wondering.” she moved down and rubbed her hand between his legs. “Maybe we should just do it.”

“Do what?” Jonathan stuttered.

“You know. The real thing.”

“You mean…?” Jonathan glanced briefly at her legs before looking back at her.

She didn’t answer him. She just kissed him on the lips. Her tongue moved out and he received it with his. She leaned further in until they both fell onto the bed.

“Do you have condoms?” she broke off the kiss.

“No.” Jonathan said disappointingly, knowing how much of a turn off that statement was.

Rachel wavered for a moment before leaning forward kissing her brother once more. They locked into a wet hungry kiss. When they were finally out of breath, Rachel pulled off.

“Promise me you won’t come inside, okay?” she pouted. Even in the darkness, Jonathan couldn’t help but to notice just how cute his sister suddenly became. Jonathan nodded out of desire. He wasn’t sure if he could hold it in when the time really comes, but he’d try.

Rachel took off her t-shirt and threw it to the ground. Jonathan did the same before he was pinned back to the bed with a hot wet kiss from Rachel. The two moaned as they writhed on his bed.

“Have you close the door?” Jonathan interrupted.

“Oops.” Rachel removed herself and trotted to the door. She closed the door as quietly as possible and locked it. She went back to Jonathan and helped him out of his briefs. His erection sprang out. She grabbed his length and wrapped her lips around it.

Her tongue delicately licked the tip of his cock. A lock of hair came down and she quickly swept it behind her ear. After adjusting her mouth to the thickness, she lowered her head, pushing his cock all the way into her. Jonathan groaned at the pleasuring warmth around his cock.

She moved her head up, her lips rubbing along her brother’s shaft, before moving back down again. His tip was moved so far back into Rachel’s mouth when she gagged, he felt the soft compression of her throat. The feeling was electrifying that Jonathan began to feel the building orgasm. He stopped his sister, removing her mouth from his wet cock. He didn’t want to finish it inside her mouth. That’s not what she wanted in the first place.

He got up and pulled her pants down. Rachel stepped out of her pants and allowed her brother to lay her on his bed. He pinned her by holding her hands down and then hungrily kissed her lips. His hips lowered and Rachel felt the tip of his manhood pressing against her clefs. The pressure mounted and gradually, her pussy spread as his length plunged deeper and deeper into her. Rachel gasped when he thrust the remaining inch of him into her.

Rachel writhed in sweet agony as her pussy stretched around her brother’s cock. Her brother slid his length in and out gently to allow her pussy to lubricate him. Once he felt comfortable being inside, he began thrusting his hips. His cock drove in and out of her tight pussy.

Her pussy clenched around him greedily. Jonathan felt the sudden tightness and roughened his thrust. Rachel squealed in delight. She never thought it would be this fun. The pleasure was immense. She was being fucked by her brother with no protection. And the fact that she’s ovulating, makes the whole thing a notch higher.

She watched her brother. His eyes were wild, consumed by the lust building between the two. He seemed out of control and for some reason, that made her pussy clenched even tighten. She’s at her brother’s mercy now. There’s no stopping him. He’s on top of her, pumping his cock between her legs. What if his brother forget about the promise? What if he keeps going until he cums? Those questions drove Rachel crazy.

Rachel felt her brother quickening his pace. It was a clear sign that he’s going to come soon. And that made Rachel’s stomach quiver in desperation for an explosive release; a release that’s only a few more thrust away.

“I’m gonna come.” her brother warned.

Rachel heart sank. Her brother’s going to have to pull out soon. But she’s about to have her orgasm as well. Her mind told her to stop her brother but her pussy wanted her to let him go on. Unable to make up her mind, she kept her legs open for her brother to pound his cock into.

“I’m gonna come.” her brother warned again.

“Don’t stop.” Rachel pleaded. She wanted her orgasm too. It would be unfair that only her brother get to release.

“I’m gonna come, Rachel…I’m gonna….shit…”

Rachel arched her back when she felt her brother’s warm potent come spurted into her fertile womb. His warm seeds ignited her orgasm and she squealed in ecstasy. Her pussy clenched hard onto his cock, greedily demanding him for more cum. His fast thrusting simmered down to gentle undulation, unloading the remaining cum inside his sister’s pussy.

“You came inside me.” Rachel accused.

“I’m sorry. I couldn’t control.” her brother heaved.

“It’s okay.” she wrapped her arms around his neck and pulled him for a kiss. “I love that you came inside me.” she added.

“You do?”

“Yes. Since you break your first promise, you have to promise me again.”

“I promise I won’t come…” she stopped him with a soft peck on his lips.

“Promise to do this to me tomorrow.” she said and her brother smiled.

“I promise.”

And the two kissed before falling into an exhausted sleep.
