Discovery, it was a possibility they lived with each time they hooked up and it was why they always exercised extreme caution. They believed that they were safe today as it was still early, but they were wrong. The teens were unaware that they were being watched because their focus was directed at each other and in this state of mind, nothing else existed.

Sixteen-year-old Scott was on top of Randi who was also sixteen and forcefully thrusting his rock hard cock inside her tight wetness and then slowly withdrawing. As he did this his lips were busy on her pert bare breasts with their extended nipples and her soft moans told him how much she was enjoying all the attention.

When Scott stopped licking and kissing, Randi grabbed the back of his head and directed his lips toward hers and they kissed slowly and enjoyed the sensation of their tongues dancing in each other mouths. The kiss ended and all movement stopped and they took a moment to enjoy the sight of each other.

Scott was tall, tanned and incredibly good looking. The muscles of his arms and chest stood out as he supported himself above her body. Randi couldn't resist running her fingers through his thick dark hair that framed his chiselled features and down his neck to his shoulders before kissing him again.

Randi also boasted a thick mane of dark hair that fell past her shoulders and like Scott her body was tanned and trim. Her looks and figure made her highly desired by all the boys at school and some of the male teachers, but they were all wasting their time. Like Scott, she was totally naked save for the sheer and silky nylons covering her slender and shapely legs which were across his well-muscled back.

When Randi tightened her legs and moved them up and down, the sensation of her nylons against his naked flesh fired him up again and resumed his thrusting. Those that had been witnessing this erotic show decided to end it and made their presence known by issuing a loud "ahem".  Both teens stopped all movement and looked toward the bedroom door and saw their parents standing there.

Scott quickly scrambled off of Randi and she attempted to cover their naked bodies with the top sheet. There was no yelling as teens expected, instead, they were told to get cleaned up, dressed and come downstairs. It was said in a calm voice devoid of all emotion.

A second later, the doorway was empty and Scott climbed out of bed. Just the sight of him standing there filled Randi with desire and despite the shock of just being caught and she knelt on the bed and threw her arms around him and another long tongue kiss followed as she ran her hands over his hard body.

Scott reciprocated the kiss and allowed his hand to caress her soft flesh. They ended this action and headed toward their bathrooms to get cleaned up as instructed.

"I guess we are in trouble big time," Randi said to herself as she stripped off her nylons.

Scott had similar thoughts and he stepped into his shower.

"There would be no way to explain this away." he mused. 

They met a little while later at the top of the stairs and together they headed toward the kitchen where their parents were waiting and God only knew what would happen then. As they descended the steps they thought about how all this came about, it had started innocently enough.

They usually talked once they were both arrived home from school where they shared the latest gossip. On this particular day, Randi was more perturbed than normal.

"What the fuck is it with you guys and blowjobs? What part of my telling them that I'm not into that don't they understand?" she asked as she pulled two cans of Coke from the fridge.

Scott was not shocked as Randi often used him as a tool for venting.

"Hey, don't lump me in with those losers. Blowjobs are not high on my list and neither is kissing afterwards as I have no desire to taste my own cock,"  Scott responded from his seat on the couch in the front room.

"What about kissing? Who teaches you guys to kiss? The last boy that I allowed to kiss me mashed his face so hard against mine I thought he loosened my front teeth," Randi stated as she set the Cokes on the coffee table and took a seat on the other end of the couch.

"Hey, it's not just the guys. Have you ever kissed a gagging goldfish? That's how Kathy Meyers kisses," Scott replied.

"We seem to keep meeting total losers," Randi replied with a smile. "I had one date that I really like and wanted him to touch me. He must have thought that he was kneading bread dough and my boobies were sore for days," his sister continued.

"I hear that. Linda Summers tried to give me a handjob once and almost gave me a rupture instead," he replied.

They drank in silence for a short time when suddenly and without warning, Randi slid a little closer to her brother.

"Call this is an experiment," she told him as she leaned into him.

Randi then placed her sweet lips on his and proceeded to kiss. It was gentle at first and quickly escalated into a long and deep tongue kiss. Scott was momentarily shocked and then responded and matched her force and movement. Randi was the first to end the kiss and she sat there staring at her brother.

"That was unfucking real, no one has ever kissed me like that," she responded with a flushed face. "Look at what you did to my girls."

Scott looked at Randi's chest and could see her nipples straining against her bra and blouse. Throwing caution to the winds Scott allowed one hand to gently trace the round firm orb under Randi's blouse while his thumb gently flicked her nipple. He expected to be smacked but was rewarded with a small ecstatic moan instead.

Randi then glanced at Scott's lap and noticed the bulge in his jeans. She allowed her fingers to gently trace the outline of the erect cock hidden under the denim. Scott tried to apologize.

"It usually takes more than one kiss for that to happen," he informed her.

Randi slid herself in even closer and wrapped one of her arms around her brother before she commenced kissing him again. The hand on her free arm began to gently rub his erection. Scott responded in kind and placed one arm over Randi's shoulders while the hand on his free arms gently caressed her breasts.

"We can't do this here," Randi suddenly exclaimed a minute later as she ended the kiss. She then jumped off the couch and flew upstairs.

Scott remembers feeling sad as he trudged to his room where he removing his jeans and donned his sweat pants. Randi's kisses were better than any he had at this point. Just as he was in the process of pulling an old t-shirt on when there was a gentle tapping at his door. A second later, he heard his sister's voice asking permission to enter and he invited her in.

She had doffed her school clothes and stood there clad in her old terrycloth bathrobe.

"Tell me, do you like girls in sexy lingerie?" she asked.

"Yeah, but I never got a chance to see any of my dates wearing any," he answered.

Randi responded by untying her robe and allowing it to slowly slide off her body to reveal a silky looking bra and panty combination in fire engine red.

"You like?" she asked placing her arms behind her back to give him a full view.

"I like," he answered. "But I thought you said we can't do this here?"

"I meant in the front room," she answered as she stepped into him and pulled the t-shirt off that had gone no further than his neck.

Randi then wrapped her arms around her brother and placed her lips on his again and began to gently kiss him. Scott responded by wrapping his strong arms around his sister and pulling her tight against his body. The sensation of her silky bra cups against his naked chest really fired him up and he kissed her harder than he had done downstairs.

When the kiss ended Randi stepped back and reached behind her back and unfastened her bra. It fell to the floor and revealed to her brother the full round globes that the bra had hidden. She took a half step into Scott again and he placed both hands the warm flesh of her tits and began to gently rub them. It caused Randi to moan out loud and was the sexiest sound that Scott's had ever heard.

Randi embraced her brother again and pushed her bare breasts against his bare chest, the sensation was beyond belief for both of them. As they gently kissed Randi felt something pressing against the crotch of her bikini panties. She looked down and saw Scott's hard cock making a pup tent inside his baggy sweats.

She once again ended the kiss and dropped to her knees and grabbed the waistband of his sweats and drew them down his legs until his cock jumped into the air. She stood up again and gave her brother a show of slowly sliding her panties down her legs. The sight of the landing strip of hair that her panties had hidden caused Scott's cock to jump.

They embraced each other again and kissed each other neck and ears as their hands roamed over each other's warm flesh. Finally, it was too much for Randi to stand and she pulled back from Scott.

"Please tell me you have protection," she said in a breathy voice.

"Always," he responded and produced a strip of condoms from a desk drawer.

Randi then flopped down on the bed and watched her brother slide the latex sleeve on. A second later, he mounted the bed and pushed her silky legs apart.

"This has to be our secret," she managed to say in a serious tone.

"I know," he replied and a heartbeat later he pushed himself into her warm and wet pussy.

That was how it started. Neither one had experienced sex as great as this and they were not about to quit. They didn't talk or joke about it in public and didn't treat each other any different at school. After school became their time as their parents weren't home from work yet.

Randi usually stripped off her school clothes and donned one of her sexy nighties before heading to her brother's room. Scott loved the sight and feel of her in them and he actually purchased her first pair of nylons and garter belt and Randi began to wear them every time they hooked up. Sometimes that was all she wore along with a pair of heels.

Due to how he reacted to the sight and feel of them she purchased a few more pairs of nylons, as well as crotchless pantyhose as they both loved the sight and feel of them. The memory reels in their mind stopped as they entered the kitchen and joined their parents already seated at the kitchen table.

The presence of the bottle of Crown Royal and their half-full glass indicated that a serious discussion was forthcoming. Both teens began to sweat and took each other's hand under the table for support. They kept waiting for the yelling to start but their parents remained calm in looks and voice.

"How long has this been going on?" Dad asked.

"About three months," Scott responded.

"Have you both been tested?" Mom questioned.

"Yes," Randi answered.

"Do you use protection?" Dad questioned his son directly.

"Aways," Scott replied.

"What about you, young lady?"

"I'm not on the pill cause I'm a minor and need a parents permission before the Ob-Gyn will write me a script," Randi answered.

"I'll take care of that," her Mom answered.

"You both know that this is potentially dangerous," their Dad stated.

"Dangerous?" Scott asked.

"Yes. Pregnancy for one. What happens if you should become pregnant?" their Mom asked.

"Then we have the baby," Randi replied.

"There is also the risk of a child being born with a birth defect or other issues from getting pregnant by a sibling," Dad replied

"We understand and will deal with it if that happens," Scott responded.

"Then there is the risk of discovery. Do you have any idea of how your friends, their families and the community would react if they discover your secret? You might be forced to leave town to escape the torment," Dad continued.

The silence in the kitchen was deafening as the teens mulled over what they had heard.

"We don't mean to scare you. We just wanted to make sure you understood the consequences of your actions," Mom said

"You know we can't condone this, but we don't see you stopping," Dad said after awhile. "We will post our new work schedules so we don't have to hear you two so please abide by it."

The teens left the kitchen and their parents remained and finished their drinks.

"Do you think they'll listen?" Dad asked after a minute of silence.

"Did we listen?" his wife responded and then kissed him on the cheek. "It's not all bad. We have two attractive and intelligent kids that do well in school and don't smoke, drink or do drugs. Their only vice is that they enjoy fucking each other's brains out. Things could be worse."

"This must be the defect that our parents tried to warn us about. We gave birth to two kids that acted as we did at that age. Do we tell them that we are brother and sister?" her husband asked.

"No. Let that remain our secret for now as we see how this plays out before we go there. They might lose interest in each other," his wife added.

"I doubt it. Did you see and hear them? I don't think they are going to lose interest anytime soon," her husband replied. "In the meantime, we need to go upstairs to our room."

"Why?" his wife asked.

"Watching them has given me a tremendous hard-on," he stated as he grabbed her hand and directed it toward his crotch and she discovered It was rock hard.

"All these years later and you still can't wait to stick your cock in your sister," she added.

"Just as you can't wait for me to push my cock inside you," her husband responded.

They headed upstairs and quiet fell over the Drake household.
