He walked over to her where she stood nervously against the door. He grinned his little kid grin and reached his arms forward to take her by the hips and draw her closer. His nose brushed against the tip of hers, his eyes were twinkling and her heart was pounding. She could feel his cock stiffening against her and his taut young body and all sense of right or wrong left her, this was the boy she wanted. She wanted to teach him everything she knew, she wanted to leave him with memories that would stand forever. The heat of his close body and her intense yearning was combining to make her face flush hotly.
"It's okay, don't be nervous. I'm not." He said softly as his lips touched hers while he spoke. "You know this is a good thing."
Any resolve to resist him was gone now, all good sense disappeared when she felt his warm breath on her mouth and she opened her mouth toward him seeking his and kissing softly and gently. He was young and excited and wanted to push further and faster but her knowledge and experience took over and she held him back murmuring to him to slow down.
Looking into his open blue eyes she took his lower lip between her teeth and tugged gently, she could feel him shaking a little as she released it and softly entered her tongue into his open waiting mouth. His tongue awkwardly joined hers, uncertain how to coordinate this, his lust was getting the better of his discretion now and he ground his hips into her belly urgently.
She knew he would not last long but she also knew he was young and could be brought to full arousal again with little effort and smiled to herself thinking this was going to the be night she finally played with her toy boy. She reached one hand up to touch his face and with her other hand she began to fumble for his belt and as she began to undo the buckle she felt rather than heard him groan in her mouth and shudder.
