I had difficulty deciding whether to place this story in the incest/taboo or nonconsent/reluctance category. I finally decided on the latter. If either category offend you, please do not read any further. Enjoy!
*****
Jasmine found herself in a similar predicament that she is frequently in these days: bent down from the passenger seat of a car with a cock in her mouth. Wesley often drives her to or from school, but he rarely does so without making her blow him on the way. Her head bobbed up and down on his cock as her hands stroked his shaft and played with his balls. His hand found its way up the skirt of her Catholic school uniform and squeezed her ass, and his head was thrown back in ecstasy. He had already driven to her house but hadn't cum yet, so they were parked in her driveway. She was grateful that her parents don't come home from work until later. She prayed that none of her neighbors would see them now.
It has been weeks since she had started at her new school: weeks since Wesley first offered her a ride home and took what he wanted from her. Almost every day since then, he has made her fuck or suck him or anyone he wished. She had vowed to stop a thousand times since, but her submissive side wouldn't let her speak out. She would then find herself doing what she would always regret later.
Wesley was about to cum. His cock swelled in her mouth and he gripped the back of her head, pressing her mouth further down onto his erection. He groaned as he came, spurting his load into her mouth. "Yes, yes! Suck me hard, Jas! Swallow it all!"
She swallowed as fast as she could, as he commanded. His body grew limp as she sat up, trying to make herself look more presentable: wiping her mouth, straightening her white blouse and plaid skirt, and running her fingers through her hair.
"Thanks, babe. That was amazing," Wesley leaned over to kiss her mouth. "I'll see ya tomorrow morning."
Jasmine nodded and left his car with her backpack, her face reddened from what she just did, parked in broad daylight. She entered into her quiet house; she walked into her living room and threw herself onto the couch. She needed a few minutes to wallow in her emotions. On top of her usual guilt, she was feeling something else.
Unusual for Wesley, he hadn't fucked her in a few days. Her pussy has been conditioned to moisten while she was sucking cock, as it usually meant that she was getting fucked after. She felt now that her panties were drenched, her pussy aching with unfulfilled need. There was no satisfaction to be had, and she had never brought herself off before. She was way too submissive to ask Wesley to fuck her or to initiate sex in any way, so now she was hot and bothered.
It was hard for her to admit to herself, but she knew that this meant that she was enjoying all her sessions with Wesley and his friends. She didn't want to want it, but she did.
She heard a rustle behind her and whipped around to see her brother standing at the end of the couch. "Connor! I didn't know you were home." He didn't say anything and just looked at her in a way he had never looked at her before. "What's wrong?" she asked, sitting up and pulling down her skirt that had ridden up. She felt his eyes all over her body and felt uncomfortable.
"Who was that guy?" He asked.
"What guy?"
"The guy that just dropped you off."
"Oh, that's Wesley, he's... a friend."
"Friend? Is that why you were blowing him?"
Jasmine gasped, completely shocked. "What?!" She felt as if her heart had jumped in her throat.
"You were blowing him, weren't you? How long has this been going on?" Connor looked so intense, so unlike Jasmine had ever seen him. She couldn't help but answer.
"Weeks. Since we moved here."
His face got even darker, his jaw clenched. "Where does it happen?"
"In his car, in his house... under the bleachers... in the woods," she had to choke the words out. She can't believe that her brother was asking her these questions and that she was answering.
"What do you do in all those places?"
"They would make me use... my mouth, and then they would make me..."
"They?!" he interrupted. "They?! More than one guy?!"
Jasmine nodded reluctantly. She felt sick to her stomach. Her brother, whom she had always looked up to, knows her disgraceful secret.
"Who?" he demanded.
"Whoever Wesley wants: his friends," she bowed her head in shame. "Sometimes strangers."
"How many guys total?"
"I... I don't know," she all but whispered.
Connor didn't know if he had ever been this shocked in his life. His baby sister fucking all these guys. She has fucked so many, she didn't even know the exact number! He looked at her: her outer appearance showed a girl so sweet, so innocent, so angelic. This contrasted sharply with what she was telling him. His dick was getting painfully hard with the mental images she conjured up: her sucking and fucking random guys under the bleachers at school.
On top of his arousal, he was feeling so much anger. For the last few years, he had been noticing her developing curves. He had tried so hard not to look, but she was filling out so nicely. He had felt so much guilt, lusting after his sister, and she had been fucking strangers. Strangers!
"Take off your clothes."
"What?!" she gasped. "You're my brother!"
His control snapped, and he grabbed her by the hair. "You stupid slut! You've been fucking half the school, and you think you're too good to fuck me?! Do you want me to tell mom and dad?"
"No!" she sobbed. "Please don't tell!"
"Then take off your clothes." He released her.
Tears welled in her eyes, but she blinked them away as she stood up slowly. She undid the buttons of her white blouse. She can't believe this is happening here in her own home with her brother. She removed the blouse and looked up at Connor. He nodded down at her chest.
