She thought of barging into the house and interrupting the obscene activity. It was her responsibility as an adult, anyway, to keep children from indulging in their mischievous depravity. In the midst of her righteous indignation, she would forget all about the lewd feelings the teens had excited in her own long-neglected twat.

But Joan had neither the heart nor the energy to leave her position of unseen voyeur. Both the youngsters knew what they were doing. The girl was not some virgin being victimized by some heartless youth. On the other hand, it was the boy who was struggling so hard to answer the seething passion of the girl's greedy cunt. The idea of interrupting them and trying to embarrass them seemed repugnant to her, not to mention hypocritical.

Besides, Joan was so wrapped up in what the teens were doing, it was impossible for her to actually contemplate putting an end to the action now, just when it was getting so hot and heavy. Her prudent curiosity demanded that she see it through. She had to watch every last moment of the progress of the lusty teenager's summer romance.

"Ellen! Oh baby… I never knew it could be so good! Shit, you're really doing it to me! I didn't know a pussy could be so tight! Oooohh yeah!"

"Do it to me, Billy! Do it harder!" Her small hands reached for his buttocks and pulled him into her. At the same time her hips lurched up to thrust her cunt up his cock-shaft. She raised her face toward his and he got her meaning. He lowered his lips to hers and they kissed wantonly, furiously.

From her place outside the window, Joan could feel the murmurs of their heated kiss exciting the nerve-centers in her swollen clitoris. She leaned her belly against the front of the house and she felt a new stab of pleasure soar through her. She positioned herself to give her clitoris the greatest possible contact with the hard surface. She stuck her fist in her mouth to suppress a moan.
