Sona bit down hard on the pillow. Her mind was a whirlwind of sensations.
Shame.
Anger.
Joy.
Lust.
The cock opening her up inside was, in a word, fantastic. The feeling of being touched and stimulated so deeply made her feel fulfilled, beyond the physical; it was a spiritual connection. She felt her soul touch Altair's.
It was nonsense, perhaps, the product of a pleasure she had never experienced before.
Altair penetrated her from behind; the lewd sounds would have made her blush if they hadn't come from his mouth. She had woken up and wanted to fight with him for fucking her in front of her sister. She never imagined she would lose her virginity in a hot tub, right in front of Serafall.
But she couldn't fight him, instead ending up face down on the bed, enjoying it, moaning, crying with happiness. Her pussy tightened every time she heard him sigh heavily, knowing that she was capable of provoking such intense sensations in him. Before, Rias had always been the sexy one, the desired one. Now, she could feel Altair's cock, hard as a ship's mast, inside her.
'Even he can desire my little body,' she thought happily.
"I'm going to cum again, Sona," Altair said between grunts. Sona looked in his direction, her hair partially blocking her view. Altair's body glistened, either with sweat or because he hadn't dried off after getting out of the Jacuzzi. "Take it inside, deep in your womb, like a good slut," Sona felt him explode. She had gotten used to it.
'Slut,' she thought as she licked her lips.
The vulgarity with which he treated her sometimes alarmed her; it was too much. And it didn't bother her at all. She had caught her sister watching AVs on occasion, in situations that seemed almost designed to see Sona.
Words like slut, bitch, whore, were quite common. The actresses were erotic, with beautiful bodies and faces. That she could be called that was comforting.
'Why did Onee-chan watch Yuri so much?' she wondered in the midst of Altair's orgasm. Her brain shut down for a second as she squeezed and came with him.
He pulled out of her tight grip, as if she didn't want that piece of flesh to leave. Sona felt the emptiness immediately, not just the emptiness, but the heat began to escape from her pussy. She heard a sound, like bubbling; it was the semen escaping from inside her.
'I... don't want it to end,' she thought with determination.
With weak legs and an iron will, she got up from the bed. She felt the dry saliva on her chin from biting the pillow. Altair's member remained erect, although it was beginning to soften.
Sona took it in her mouth, the taste was... different from when she sucked him in front of Aika. 'It tastes like me,' she thought, and for a moment she believed that Serafall would enjoy the taste too.
'Did she realize what happened?' she wondered suddenly, a secondary thought as she felt her future husband's cock harden inside her mouth.
'Onee-chan wouldn't have allowed that to happen in front of her.'
Pop!
She took his cock out of her mouth, a dull thud echoing through the room.
"You seem quite eager, Miss Sitri," Altair teased.
Sona looked up at him from her position. His body sprawled across the bed, his abdomen marked and his chest broad, his arms thick, though not quite reaching the physique of a bodybuilder.
"Shut up," she said.
Sona positioned herself on top of Altair, her legs on either side of his crotch, lowering herself slowly. With one hand, she grabbed his cock and guided it to her vaginal lips, inviting it in.
"You didn't say we shouldn't do this," he said, a smile adorning his handsome face.
"I said shut up," she tried to sound bossy, her tone of voice duly trained to deal with problematic students, such as bullies.
Or perverts.
"As beautiful as your moans are, you still don't know how to stick it in," Altair said.
"Black-san, don't speak again," she said sternly.
"Did you like being deflowered in front of your sister so much? I think Serafall enjoyed the show," he commented lightly.
Sona lost her balance when she heard her sister's name, accidentally falling on the boy's cock.
Only this time, it entered the wrong place. Sona looked ahead in surprise. Even Altair's eyes were open, as if he hadn't expected her to take him there.
She expected pain, but she didn't find it, at least not as much. She still felt a slight discomfort at being taken in so unnatural a way. She remembered that Altair had penetrated her with his fingers, and she thanked him for getting her used to it a little.
"Stay still!" she said to him.
He had tried to change position, probably for her comfort. But she couldn't allow herself to show complete weakness in front of him. 'I don't want Altair to think he can do whatever he wants with me,' she thought.
"Relax," he whispered.
Sona felt a chill in her anus, but soon the cock stopped feeling bad. She let out a moan of satisfaction that made her cover her mouth with her hand.
"Ah, at least he's considerate," she thought.
"You can take it out now," Altair said. She frowned, considering whether to obey his words or not.
"I can take it there," she said.
She started slowly, getting used to the sensation. It wasn't like her vagina; her anus wasn't made for sexual satisfaction. However, she enjoyed it. That same feeling of being filled to the brim, of feeling stretched and used. Of knowing that Altair enjoyed her small body.
She moved up and down, looking ahead. Altair was staring at her with his mouth half open. She went down to kiss him. The kiss was wet and controlling; she still couldn't beat his tongue, and deep down, she never wanted to beat him either.
Altair's hands went to her waist, helping her move, not controlling her.
Her movements were initially to move her body up and down, letting Altair's cock stretch her insides over and over again.
Those movements changed little by little. It wasn't just penetration; her hips moved in circles, from side to side, back and forth. She began to feel her walls caressed differently.
"Agh!" Altair began to enjoy it more, judging by the sounds that reached Sona's ears.
She began to move her hips more easily, though it was still difficult for her. However, she could control her pleasure more than when she did it vaginally. Honestly, she didn't feel as much pleasure from the back door, but she enjoyed watching Altair enjoy very much.
She let out her own moans when Altair's mouth latched onto her breasts like a calf seeking its mother's udder. Altair seemed desperate to suck and lick them; she even felt him bite them. She didn't dislike it at all; all she wanted was to be desired and used for his pleasure.
Sona rolled her eyes when she felt Altair's fingers enter her pussy, but they didn't stay there long.
"Taste," he said in an authoritative voice as he presented his fingers to her. "Keep moving your ass," he ordered with a slap when she stopped.
Sona sucked Altair's fingers, coated with the taste of her cum-filled pussy. She sucked them as if they were a cock, even though Altair's cock was much bigger.
"You're going to finish inside me... that will be... your punishment," she said as she moved frantically, the cum in her mouth serving as fuel to accelerate her movements.
"I hope to carry out many more punishments," Altair said as he hugged her from behind.
Sona felt it, like a hammer, Altair's hips began to pound upward, inside her tight hole. She let herself fall onto his chest as her legs gave way. She squeezed tightly, felt his movements stop for a few moments before he picked up the pace again.
"Fantastic," she whispered over him.
She could feel the exact spot where his balls bounced, giving her wild sex a greater sense of intimacy. Altair's breathing became heavier and heavier as he approached orgasm.
Sona kissed him, feeling his hands squeeze her as his cock slightly increased in size.
'He's going to cum!' she thought happily, as she prepared to collect his semen inside her tight little ass.
She felt his hands grab her buttocks as he began to cum inside her with a firm thrust.
She leaned back on his chest when she felt her ass take the last of his shots.
'I think I love him,' she thought dazedly.
