Summary: Andrew's slutty sister test his vow of purity
Andrew came home from church camp with a renewed sense of spiritual purpose. Each time he attended, it was as though he could feel the Holy Spirit having touched his shoulder and assured him that he was on the right path. Having just graduated from high school this year's camp had focused on a special lesson that Andrew felt certain was going to help him succeed in life.
Already a virgin, Andrew took to the lessons about abstinence readily. The distractions caused by a girl's body, the temptations of their soft curves and seductive eyes, had led a few of his friends astray already. At least one was going to be a father, right out of high school. Andrew had seen the distress it had caused in his friend's life, as well as that of the girl. Andrew, himself, didn't want that. He was intent on making the most of himself and pursuing a real career. When he met the right woman, then he'd consider giving in to temptation in a way that was right and holy, one that conformed to the ideals of his church and the will of The Lord.
Andrew came home to find his sister's car in the driveway. Two years older than Andrew, Becky had been away for the whole year for her sophomore year of college, attending a school six states away. Andrew was excited to see his older sister, and couldn't wait to tell her all about his new vow of abstinence, to show her his purity ring, and to have her support. Maybe he could even get Becky to adopt abstinence, herself, as a show of familial solidarity.
He found Becky in the living room, lying on the couch, watching TV. His sister perked up at his arrival, running forward to give him a big hug and squashing her large, braless tits into his chest.
"Oh, my God! It's so good to see you!" Becky squealed excitedly, "How was your little Jesus camp?"
Andrew was slightly embarrassed at having his retreat referred to as a "little Jesus camp," but he ignored the jab and touched his purity ring. The feel of Becky's large, soft, and obviously braless breasts was the first real test of his vow. He could tell that it was the devil's temptation, too, as it made him think about large, jiggling tits and that those tits were his own sister's. It was a double whammy that had involuntarily made his cock twitch.
"It was really great," Andrew said, seriously, "When did you get in?"
"Just a few hours ago," Becky answered, "Do you think you can help me take some bags out of the car?"
"Sure!"
Andrew aided his sister in taking her bags in. While she unpacked and put her things away, Andrew related the remarkable tale of his spiritual journey at church camp. Becky laid out her things on the bed prior to putting them away, sorting out the mess of clothes into matching piles. Among the piles were several pairs of very tiny, lacy panties and bras that she set right next to Andrew. The sight of them made her brother blush as he stammered about his vow of abstinence.
His eyes kept drifting to the little pieces of cloth, the devil's temptation putting images in his mind of where those panties and bras had been. Becky left these articles for last, forcing Andrew to sit next to them uncomfortably as she put everything else away.
"So, you're going to be like a monk or something?" Becky asked, "You're never going to have sex?"
Andrew laughed and shook his head, saying, "No. It just means I'm saving myself for the woman I'll marry, so we can begin our life together in purity."
Becky giggled a bit at the dreamy look in Andrew's eyes as he imagined himself and the unnamed future wife.
"What if she's not a virgin, though?" Becky asked, arranging her make-up table.
"I'm not going to force my own beliefs on anyone," Andrew said, shrugging, "People are who they are. My choice doesn't have to be everyone's. If we fall in love, I'll love her for who she is, not who she was."
"That's really sweet," Becky said and gave him another hug, this time pulling his face into her cleavage and smothering him with her tits.
Andrew flushed as his cock hardened, betraying him. Becky held him a moment longer before letting him go.
"What if she's disappointed, though, because you don't know what to do when it's time to get it on?" Becky asked.
Andrew blushed and stammered, "I... I'm not worried... about that."
Becky shrugged and said, "Okay. I guess we'll see how long you make it."
Andrew furrowed his brow in confusion and asked, "What does that mean?"
Becky grinned, saying, "Boys aren't made for that shit, Drew. Especially eighteen-year-old boys. You'll be jerking off by the end of the week."
"That's... No, I won't! That's gross!" Andrew argued.
Becky shrugged again and said, "We'll see. I want to have a nap. It was a long drive."
"Yeah. Okay," Andrew agreed, leaving his sister alone.

That evening Andrew made dinner and Becky helped. He didn't feel it was all that appropriate for his sister to putter about the kitchen wearing only a pair of the sexy panties and a tank top, but he focused on making the meal. Becky had other ideas, though. While Andrew kneaded meat patties, Becky wrapped her arms around his waist and pushed her tits into his back. Her hands rubbed his chest and she whispered in his ear.
"I'm so glad to be home with you. We can have a lot of fun this summer, just me and you."
Her tongue snaked out to flick his earlobe and one hand strayed downward to lightly brush his cock through his jeans.
"Don't do that!" Andrew protested, his hands covered in meat juice, "That's wrong on so many levels."
"If you can't take a little teasing," Becky argued, "How are you ever going to keep up this vow of yours?"
Andrew blushed but didn't say anything. Becky returned to stirring a cornbread mix.
During dinner, Andrew recounted, again, his tale of church camp to their mother. Under the table, Becky casually ran her foot up his leg and pressed her toes into his crotch. She gave him a little smile across the table when she felt his cock harden. Andrew only blushed and stammered about his vow of abstinence.
"That's really sweet of you, honey," their mother said, "If it's what you really want, I'm sure you'll do fine."

As Andrew lay in bed that night, he sighed into his pillow and tossed. His phone pinged with a message and he muttered to himself about having forgotten to silence it. The message was from Becky.
"Hey, I'm really lonely. Would you just snuggle me for a bit, like we used to?"
Andrew went to Becky's room, thinking of all the times that Becky had come to his bed, or called him to hers when they were kids. Becky was always an affectionate girl who liked to be held. Many nights, while growing up, he'd needed to lay with her until she fell asleep. It had been many years since it had happened, but he supposed having been away for a while had brought those memories back. He went to Becky's room and knocked lightly.
"Come in," came the reply.
Andrew let himself in.
"You okay?" he asked with genuine, brotherly concern.
"Yeah. Just kind of lonely. My roommate and I sleep in the same bed a lot, so I'm just kind of used to having someone with me. Do you mind? Just until I fall asleep?"
"Alright," Andrew said, and slipped into the bed, laying on his back.
"Not like that, Drew. Hold me," Becky said.
Andrew sighed and turned on his side, putting his arm around Becky's waist. His sister wiggled her bottom and spooned into his crotch to get comfortable, then sighed contentedly and was still. Andrew lay against her warmth. It felt nice, he decided, after so many years. He settled in and began to drift off.
Andrew was nearly asleep when Becky, lazily, rubbed her panty-covered bottom against his crotch. He grumbled but was near sleep. A moment later, Becky pulled his hand from her waist and put it on one of her breasts. Still sleepy, Andrew barely registered this, but then he gave her tit an unconscious squeeze and felt her nipple harden. He tried to pull his hand away but Becky mewled, sleepily, in protest and clung to his hand. Her ass wiggled against him again and Andrew found his cock hardening involuntarily.
"Becky!" he hissed.
His sister mumbled tiredly.
Andrew's hardon pressed into the crack of her ass and he was acutely aware, now, that he was groping his sister's tit in his hand. Finally, he was able to get his hand away. Quietly, he snuck out of Becky's room and slept fitfully the rest of the night.

Andrew made his way to the shower in the morning, but the door to the bathroom was wide open and the water already running. He could hear Becky humming to herself in the shower. Averting his eyes, he reached in and shut the door, then returned to his room to wait his turn. His cock was hard again. He rubbed his purity ring, said a small prayer to himself, and busied himself reading a few of his scriptures. Once he heard the bathroom door open he waited, then took his turn in the shower.
When he made his way downstairs, intent on making breakfast, he heard sounds from the living room. Upon entering to investigate, he was shocked to find his sister with her legs spread on the couch, masturbating while watching porno very loudly on her phone.
"Becky! What the heck!" Andrew cried.
Becky only moaned and continued to finger her twat, now watching Andrew with a lusty, glazed expression. Andrew quickly fled back up the stairs. He threw himself on the bed, prayed, and hid in his room. After some time, Becky let herself into the room without knocking. His sister wore only a tank top and Andrew's eyes fell on her naked pussy.
"Becky!" he cried.
Becky quickly approached, put a finger on his lips, and pressed something into his hand, then ran from the room. Andrew, stunned, opened his hand and found a pair of Becky's panties balled up in his fist. The panties were very wet. Blushing, Andrew took the panties to the hamper and put them in, then marched to Becky's room. He knocked at the door.
"Come in," Becky called.
"Are you decent?" Andrew asked.
"Yes," Becky said, and Andrew opened the door.
Becky lay on her bed, stroking her wet pussy with one hand and watching porno on her phone.
"Becky! Cover up! Oh my gosh!" Andrew yelped, covering his eyes.
"It's my room," Becky said, "What did you want?"
Andrew could hear the sound of the porno playing and the slick, wet sound of his sister's fingers playing with her pussy.
"Nothing!" Andrew said and shut the door.
