“You’re making me wet.”
“You made me hard.”
“I want to make you harder, too.”
“Do you want to suck me again?” he asked. She didn’t answer him but neither did she stop staring at his cock. He stood next to her, offering his cock to her.
“Damn it,” she said, eyeing his prick. “I told you what this does to me.”
“Just do it for a minute,” he suggested. “It’ll make me really hard and needy.”
“For one minute,” she agreed, leaning over and engulfing his hard cock with her mouth.
As soon as she got started doing it, it became obvious to him that this was something she truly loved to do. She explored his cock with her mouth and tongue, teasing him and then looking up to see his reaction. Most of that reaction she could feel against her tongue. He had no idea how long she sucked him. He wasn’t timing her, but he knew it was a lot longer than one minute. She bobbed her head up and down him really fast for a few seconds before pulling back to rub his wet cock against her cheeks while looking at him. On a whim, he smiled and said, “You’re such a good cocksucker.”
“Fucker,” she groaned and she did it some more.
“I’m serious,” he assured her, petting the back of her head. “You suck dick better than anyone.”
“You’re making me wet,” she said between mouthfuls.
“That’s because you love dick,” he said with a big smile.
“Mm, I do,” she purred, back to rubbing her face against his crotch.
“Suck it, Robin. Suck your little brother’s big dick.”
After moaning loudly, Robin did exactly that. She also began clutching at her body while she did it, too. “Keep talking dirty like that.”
“You mean I should keep calling you a cocksucker?” he asked.
“Uh-huh,” she moaned as her hand moved from raking across her chest. She clutched her pussy. “I love that word.”
“Cock?” he asked, hearing and feeling her moan as she kept her mouth wrapped around his prick. “Suck it,” he said, unsure what else to say aside from repeating himself. “Suck my cock. Suck your brother’s cock. Suck my cock and make me cum.” The more he said all that, the more turned on she got.
She pulled back and stroked his hard cock. “It’s okay if you want to cum in my mouth. I like that, too.”
“I’m not sure that I can,” he groaned. “Not yet, anyway.” The sheer number of amazing orgasms from earlier in the day had cursed him. He had felt this way before when he was with Suzanne. He could get excited. He could get hard. But an orgasm felt really far away. “I need a lot more cocksucking before I can get there.”
“Mm,” she moaned, giving him that more for a long time.
Feeling stuck, he glanced at the TV and watched part of the videotape for inspiration. It helped, but not enough. As good as his sister’s mouth felt, he was afraid it wasn’t going to be enough. He really wanted to get off again, but he was afraid it was going to take so long that he would wear out her mouth.
“Let me jerk it for a minute,” he said, pulling away from her. When he touched his cock, it was wet from her spit and that felt good. He pulled and tugged on his cock, first staring at the TV and then glancing at her. She stared directly at his cock as she rubbed her pussy and he saw that hungry look on her face. Damn, she looked sexy. She might be his sister, but he saw the fires of lust in her eyes and wanted to make her happy. “Fuck!” he groaned, disappointed that he couldn’t seem to bring himself closer to an orgasm for her.
