Kit felt for Betty’s closer hand and pulled it to his erection, black he pushed it down the front of his briefs then rolled his back, forcing his cock through her fingers. She needed no more hints. Sister began stroking brother as he slipped his hand into her underwear for direct contact with her. And they stayed like that, touching, caressing and fondling each other until the young girl went stiff then began to convulse. When Betty sucked a deep breath, Kit slapped a hand over her mouth to keep her from alerting the house. She rocked and vibrated but her moans were muted by her brother. When she relaxed Kit pulled his hands off her. She rolled her head to look at him then silently got off the bed and returned to Maggie’s bed. Kit still had a massive erection but he didn’t mind. He was sure what he had done for Betty would be enough to bring her back the next night. Betty spent the rest of the night lying with Maggie but she was not cold. She basked in the warmth generated by her thoughts, by the aftereffects of the strong climax Kit had caused. As she remembered how his hand felt between her legs, her fingers stayed busy in her panties, Betty had a second, stronger orgasm before she managed to sleep. All the next day the half-sister surreptitiously watched her half-brother, thinking about what they had done, how his erection felt under her fingers as he fondled her. In the morning she had wanted nothing more than to continue the intimacies, but by the time dinner was over, so were her tainted thoughts. She vowed to herself to remain with her big sister that night. True to herself Betty remained in bed with Maggie the entire night, she didn’t get a lot of sleep, but enough to justify staying. The next morning Betty met Kit as he came from the bathroom, they paused in the hall just long enough for him to boldly say, “Where were you last night, I missed tits you?” Betty flushed with embarrassment, her heart fell to her stomach, she turned and sucking fled to the bathroom without saying a word. Never in her life had she ever experienced a sensual rush like the one his question triggered. It was 1:32 in the morning when the girl gave in to nature and crept to Kit’s room. It was too dark to see him; she didn’t know if he was awake and waiting or if he was asleep, but that didn’t matter. What mattered was the unrest in her loins, compelling her to him. She was still naive about boys and girls but knew with certainty she needed to be near skinny Kit. She laid on the bed, too hot to cover herself, eased her hand between her legs as she put her eyes on him again. Kit wasn’t asleep, he’d been waiting. He’d watched her all day and was sure she would return to his bed that night. His cock had been hard since he went to bed, waiting for his sister to come to him. He rolled to face Betty, hooked his fingers in the band of her pajama pants and tugged them down. Betty bbw lifted her ass, then in seconds she was free of any material covering her lower body. She put a hand on the bulge of his erection and stroked it strongly a few times then dipped her hand under the elastic of his shorts and helped him pull them down. Kit went up and over Betty, she moved her legs wide apart so her half-brother could take her. Logan squirms in his chair and bbw tries to adjust his throbbing hard cock secretly. “If I give you to someone else, man or woman, you would please them as you would me?” I assured him I would and smiled. However, a secondary idea came to mind. My balls pounded against her ass as I thrust. I probably will get kicked out. She was moving slowly, and her eyes black were glazed. I accused her. Then he reached for tissue and I put together what the tissue was for and what he had tasted the other night. I waited until Ryan was home to try them on. I couldn't wait. "I'm well prepared," he grinned "I took a Viagra earlier." Kate and Jude had big sucking smiles on their faces. It was time to test things out. “Dude! That change in perspective is much like what you go through tits after attending a nude beach for an extended period of time, where you loose your body consciousness and you become less judgmental of body types. She silently despaired at skinny what was her life coming to. It seemed inconceivable that they could have followed us across the country to this little town in Iowa. You usually don't get home this early." "Oh!
