As she watched the youngsters writhing out their passion on the couch, she was reminded of how it had been between her ex-husband and herself, back in the earliest days of their courtship, when they were both freshman in high school.

Fred had not been pudgy like the boy on the couch. He had been lean and hard from his workouts on the track team. But he had had that same boyish enthusiasm that the boy called Billy was demonstrating. New to lovemaking herself, she had been afraid that Fred would hurt himself with all his panting and straining and groaning. But he had not hurt himself.

He had only succeeded in making her pant and strain and groan with the same abandoned fervor.

Memories of how good passion had been then – when she had been young and truly in love with a boy who was in love with her – made Joan's excitement now all the more intense. She felt herself almost rooting for the boy, and for the girl too. She wanted to see them go all the way. To scale the heights together.

It was apparent from the building excitement in the house that the teenagers had exactly the same idea. Billy sent his hard cock soaring again and again deep into the blonde's hot cunt. His cock gleamed with her juices each time he pulled it from her clinging hole. From time to time, his mouth went back to seek out her lips and they kissed hotly while his cock skewered her pussy.

Their exclamations of pleasure were no longer coherent. Only garbled moans and shrieks escaped their lips as Joan watched the boy's buttocks lunge more lustily forward. The girl did not even have to coax him or pull on him any more. She was too immersed in her own ecstatic bliss to guide the boy's activity. He was too close to the sweet promise of orgasm to even be aware of the superhuman effort he was making. The effort was easy with the hot clinging folds of her cunt to reward him on every feverish stroke.
