Now that I'm thirteen, these three are giving me hard-ons just all the time whether or not they know it. I mean, I'm thirteen, right?My true appreciat...on for having three older sisters came one evening when I was just turned thirteen and was laying in bed with my hand under the covers playing with my dick when a knock came on my door.Of course, I pulled my hand up and called out, "Yeah, come in," and in came all three sisters to crowd around my bed."All three of you? What's up?"They're looking. "This is strange," he murmured, though it was only to himself. But his mother, her attention attuned to her son who had become quite the embarrassment, heard."What is strange?" she asked quietly, moving the hankie from her face."It is growing," Reginald said, stroking his hand over the lump of flesh that had never seemed to show much interest in anything but sleeping contentedly against his flabby thighs."It is? Let me see," his mother said, pushing his hand away and rolling to her knees,. She only pushed his back down, his bound hands nestled between their stomachs wrapped around the cock she still wore as her hands braced themselves on his chest and she rode him while moving just her hips.She unlatched his restraints at his waist and moved his hands up to her throat. “When I loosen the leash, let go…Squeeze.”He did as asked. She came to a rest on his cock and swiveled her hips in a clockwise, then counter clockwise motion. He could feel the ball of her cervix with the tip of. “I am sorry, Emily.” “Full of apologies, David, aren’t you? That’s at least three already.” “Sorry.” “Four.” She was toying with him, David realized, but he was unable to assert himself. He also realized that perhaps he didn’t really want to. Forgetting his earlier resolution of ‘nothing too obvious’ his eyes lingered hungrily on Emily Chang. He drank it all in, those lovely bare legs so gloriously crossed and flaunted in the tantalizing skirt, those firm and bountiful breasts jutting out.
