In Clair's ass

As much as the sight of his **** sister-in-law had grabbed Joe's attention, it had also made him realise that at this moment his wife was in no position to resist whatever he chose to do. Looking down, there was Helen's slack features. Above them was Clair's wet pussy, lips stretched around his cock and shiny with juices. Further up still was puckered ring of his wife's anus, almost hidden between the full globes of her ass.

Pulling his shaft free of her wet slit, he pushed down on her shoulders. Her head dipped, resting on the bed between her sister's thighs. With his wife positioned, her aimed his cock head at the enticing wrinkle - one Clair had denied him up to now.

As he touched it, Clair went to push up but found his hand on her back kept her immobile. She whispered urgently "No, Joe, what do you think you're doing!", but any louder protest was unthinkable, lest she wake Helen. As unpleasant as the though of a cock up her virgin ass was to her, the idea of her sister waking to discover them like this was worse still.

Joe's cock pushed against the tight ring. Clair's pussy juices helped, but she was resisting and it was hard work. Undeterred, he continued, finally working the head in with a quiet pop and a barely muffled squeal from Clair. Leaning his weight forward, he let gravity **** more of his shaft into her, an exquisite tightness sinking down the length of his dick. With his head close to Clair's now, he could see a line of tears and her breath coming in sharp gasps, eyes unfocused, as well as the equally thrilling sight of her sister's shaved pussy only inches away.
