Polly Cooper - Betty's sister

The door opened to reveal a pretty strawberry blonde girl - It was Polly Cooper, Betty's older sister! She was dressed in a tank top and shorts, apparently having just finishing exercising. Archie noticed the sweat glistening on her skin, her chest heaving ever so slightly as she held the door open.

"Oh Archie, long time no see!" she said, "Did Betty know you were coming? She just went to buy groceries a few minutes ago, in fact you just missed her!"

"Hey Polly! Ah, actually I wanted to surprise her!" Archie smiled, "But it looks like the surprise is on me! "

"Oh ok, she should be back in about half an hour or so, you wanna hang around here?"

"Yeah sure, why not?" Archie said, as Polly led him inside. Archie could barely keep his eyes away from her heaving breasts. Now as Polly led him inside, he took notice of her shapely ass. Her short shorts did nothing to hide her long toned legs. He hadn't seen Polly in a while - he forgot how sexy Betty's sister was. Good looks really ran in the Cooper family, even their mother Alice still looked good at her age. His dick slowly grew harder. Entranced by the sexy ass in front of him, Archie failed to stop in time when Polly paused to turn around, ramming his stiff cock into her ass. Polly gasped as she felt the stiff rod poked her, she could feel the point despite being under his jeans.

"Oh Polly, I'm so sorry!" he apologized quickly, hoping she didn't notice his throbbing length.

"Uh no problem at all.." Polly replied, suddenly curious about her little sister's boyfriend. An akward silence followed.

To break the sudden silence, Archie decided to keep the conversation going.

"You back in Riverdale for good?", he asked.

"I'm actually here on a break from my reporting job. Our parents are in Central City for a wedding, so they'll be gone the weekend."

"Oh so you're a girl home alone? Tsk tsk...so when the cats are away, the mouse will play!" he said, in a joking tone.

"Well Betty's around, but if there's a difference between me and my baby sister, if I really wanted to play, nobody would find out!" she said with a glint in her eye.

Was Polly actually flirting back at him - Archie thought. Should he push further?
