ETHEL AND MARK Sunday morning Ethel and Mark went downstairs in shorts and Ethel with a tube top. They told their grandparents they didn’t feel too well and didn’t want to go to Church. The agreed and allowed Mark and Ethel to stay home. As soon as their grandparents left, the two children, Ethel 10, and Mark 8, ran upstairs to their room. It was Mark’s turn to be naked and tied this time. Mark wasted no time in taking off his clothes. Ethel had never seen him naked before except for when he was a baby. Now that he was older, he should have had more modesty. But he wanted his sister to tie him up naked and play with him until he came. He had often masturbated himself, and knew what to expect. “OK, sissy, tie me up however you want to. I’m ready.” Ethel told him to stand up. When he did, she tied his wrists together in front of him, then roped his upper body and arms, pinning his arms tightly to his sides. She made sure his nipples showed through the ropes. She gagged and blindfolded him just as he had done to her. Then she told him to get on the bed and lay back face up. He did the best he could. Ethel got on the bed between his knees, then pulled his feet in front of her, and tied his ankles crossed, wrapping rope around them both ways until he couldn’t move them. She tied another rope around his wrists with long ends left over, then pushed his ankles toward his head. She pulled his wrists up and tied them directly to his ankles, forcing his butt slightly up opening up his anus for her. She could easily reach his cock and balls. “Now, let me see, what can I do to you?” “Mmmmmpppphhhhh,” he murmured through his gag, trying to tell her what to do. Of course, she couldn’t understand him. The first thing she did was begin to flick her finger against his butt hole. This caused him to jerk in his bonds. She speeded up the flicking, causing him to really writhe in his bondage. She began to tickle his feet, and bound as he was could do nothing. He laughed and yelled, trying to writhe around enough to get away from her tickling, but to no avail. She continued to tickle his feet for a good fifteen minutes until he was worn out. Then she used her mouth, biting his toes and the soles of his feet. He couldn’t even move. Then she stopped, and wet a finger getting his anus as wet as she could. He felt the wetness and wondered what his sissy was up to. Then he felt the finger press against the opening. He protested, “MmMMMMmMMppPpPhHhhHh!” She ignored his protests, and continued to push her finger into his anus until she had it in as far as she could get it. She let it rest deep inside his bowels, and he settled down. With her other hand she grabbed his penis lightly and began to rub the head of his cock with her thumb. This sent him into throes of sexual excitement. His cock began to become erect. She continued her rubbing, and the wetter his penis got the harder she rubbed. Then she grabbed it around, and began to pump, making sure the bottom of her hand banged against his balls. As she pumped his cock, she moved her finger in and out of his butt hole. He began to move with her, and she watched as he tensed and his semen spurted onto his chest and stomach, then flow down his penis. She pulled her finger out of his ass, then bent her head over and began to lick and suck on his cock, licking up all the semen off his chest and stomach. Then she took his cock into her mouth, and began to use her mouth on him, one hand playing with his balls. As she sucked, he became hard again, and she continued until he came again, and she swallowed every drop. She cleaned him up by licking all over him, then untied him. He stood in front of her, completely naked, and gave her a big naked hug. They dressed and got downstairs just as their grandparents got home. “So, what have you two sick children been up to?” they asked their grandchildren. “Oh, just in bed, resting quietly, tickling each other sometimes.” “Well, that was nice.” They never knew what their grandchildren did during their time alone. |
