That was all it took. Marla had melted immediately. She pressed the teen's hand hard against her tit, and tilting her mouth to his for a kiss, moved her hand to his cock. The first feel of a throbbing, hard cock had caused her to come, and she had squirmed her mouth against the teen, mewling as her cunt went through a series of contractions, gripping his cock through his pants. By the time the guy had his cock inside her cunt, Marla was almost out of her mind. She thrashed and churned beneath the guy in the tight confines of his car, screaming and shrieking with more ecstasy than she knew there could be. Her cunt had throbbed into orgasm again as soon as his hard cock penetrated her cunt, and the contractions kept going constantly as the guy fucked frantically, pounding his cock into her gripping pussy.

He had told all his friends what a wild fuck Marla was. Most had trouble believing that the exceptionally beautiful girl was such a hot one, but the guys did start pressing her for dates. But Marla, afraid of her own sexual responses, almost became a recluse.

From becoming known as the easiest, hottest fuck in school, she became known as a stuck up, frigid bitch. Only Marla knew she was by no means frigid. She had a terrible time controlling herself, and spent almost every night using her fingers on her body, plunging them into her cunt and coming so hard and often, she had difficulty walking the next day.

She looked at her reflection, becoming more excited. She could see the moisture growing on her panties, feel the heat of her cunt. Her sharp pointed tits began to push at her blouse, her nipples sensitive. So absorbed in her erotic activity, Marla failed to hear the soft breathing behind her.

Peering around the door, Bob and Sally were watching their mother. It wasn't the first time they had spied on her, but it was the first time they had seen her using the mirror this way. Bob's cock was pressing at the front of his pants, very hard, his balls aching slightly. Sally, a year older than her brother, was experiencing a delicious, moist heat between her thighs. Her tits were swollen inside her summer sweater, her tiny nipples making points against it.
