Clair plans to tease Joe

Joe and his wife lay there for a while, enjoying the memory of the evening. Clair whispered to her husband, "You know that's never going to happen right? Watching and fantasizing is one thing, but she's my sister."

Joe didn't reply. Clair started to repeat herself, stopping when she heard the rasping intake of breath that was Joe's snoring. Typical, she thought, although a wry smile spread across her lips as a devilish plan formed in her head. She just hoped that Helen would agree to it.

When Joe woke late in the following morning the house was empty. He found a note on the kitchen table that said Clair had taken Helen sightseeing and wouldn't be back until later in the afternoon. Joe absentmindedly stroked his cock as his thoughts drifted to last night's viewing, and Clair's incestuous intentions toward her sister. His cock stiffened at the thought of the two sisters together, and it wasn't long until he came forcefully, spurting across the kitchen table.

The rest of the day passed slowly as he waited for the ladies to return. It was early evening by the time they bounced through the door, giggling, and laden with shopping bags.

"See many sights in all those shops?", Joe quipped.

"Very funny," Helen replied, "I've convinced my little sis that we need to go out tonight to celebrate my last night here. I had nothing to wear, so we've been dress shopping."

Clair ushered Helen up the stairs, turning to give Joe a wink, "We're going to try on dresses in Helen's room, and then head straight out. I suggest you go up to our room and make yourself look dashing."

It only took Joe a moment to realise Clair was giving him the opportunity to watch them trying on dresses.
