Beth

Amy looked over at Beth sitting next to her and looked her body up and down. “It looks like you and me are the only ones still wearing any clothes,” she laughed. “I probably should dare you to take off your panties, then I’d be the ‘winner’ if we were playing strip poker. But we’re not playing strip poker and I have a better idea.”

Beth looked at her quizzically.

“I dare you to give David a lap dance for two minutes.”

That got my attention.

“But he’s naked!” Beth pointed out.

“So?” Amy asked. “At least you’re still wearing panties. And don’t act like you don’t want to do it.”

Beth grinned and got up from the sofa and walked over to my chair. She looked down at my boner sticking straight up in my lap. “You happy to see me?” she grinned.

She leaned over and shook her tits in my face, then turned around and wiggled her ass for me. She looked over her shoulder with a smile as she reached behind her back and put her hand on my stiffie trying to push it down some. I pulled my legs together and she spread her legs outside of mine and sat down in my lap. My hard cock was trapped between her soft ass cheeks. I grabbed her hips as she began grinding on it in my lap. The pleasure was excruciating and I wasn’t sure I would be able to stop myself from cumming before she was finished.

I slid my hands up from her hips and covered her firm tits with both hands, massaging and squeezing them as she slid her ass all over my thighs and dick. I had lost track of time but apparently there was still some left because Beth stood up and turned around and sat back down in my lap facing me. Her vulva pushed my throbbing shaft back against my chest. I was sure her panties felt wet as she squirmed around sliding up and down against my cock.

I had my hands on her ass as she bounced up and down. I started to bend my head down to get a tit into my mouth when Amy called out that dreaded word, “time!”

Beth gave me one last wiggle of her ass before getting up. “I guess I don’t have to ask if you liked that,” she smiled, looking down at my bobbing cock. The she turned around and went back to the sofa.

I just sat there trying to concentrate on keeping my tingling penis from shooting off. If I was going to cum, I wanted it to be in or on somebody.

“David!” my sister called me out again. “You going to pick someone for a new dare or go fuck Beth? Wake up, bro.”

I stuck out my tongue at her. “Unfortunately, I don’t think that was part of the dare.” The girls giggled again but Beth also gave me a little nod and a wink. “Maybe later?”
