Beth

Susie nodded her head. “Yeah, I’m ready,” she grinned. “So this is maybe just a little variation of a previous one but I have a little twist to it. Beth, I dare you to do 69 with David. You suck his cock while he eats your pussy. The twist is that whoever cums first is the loser and will have to do a forfeit.”

“Sure, that works for me,” Beth replied readily. “You want to be on top or bottom,” she turned to me and asked.

“Um, bottom I guess,” Not really sure which one was better. I figured her being on top would give her more room to bob up and down on my shaft. “But what’s the forfeit?” I turned to ask Susie.

“Don’t you worry about that, bro,” Susie grinned. “You better just worry about winning.”

That sounded ominous enough to me that I didn’t want to question her any further. I just wanted to concentrate on making Beth cum before I did.

I lay on my back on the floor in the middle of the room and Beth came over and knelt down with her knees on either side of my head. She squatted down a little so that her naked wet pussy was almost touching my nose then leaned forward with her face in my crotch and grabbed hold of the flagpole standing up from my pelvis. I grabbed her hips with both hands and directed her warm hole down onto my mouth and started licking.

At the same time, Beth started stroking my hard rod up and down with both hands then I felt her warm moist lips encircling the crown of my throbbing cock. It was so sensitive by now that I almost jumped out of my skin when she first touched it. Then she started taking the rest of it into her wet warm mouth slowly working her way down until her nose bumped my groin. She still held onto it right at the base with one hand and started massaging my balls with her other hand. Then she started bobbing up and down on my long shaft making no pretense of going slow and extending my pleasure. She obviously intended to be the winner of this contest.

I tried my best to ignore the distraction of what Beth was doing to my cock and concentrated on her pussy. I licked her slit back and forth with my tongue flat slowly pushing her outer labia apart. Her hard little nubby clit was revealed and I reached around with one hand and pinched it between my thumb and forefinger then started rolling it. I made my tongue more spikey and pushed it between her fleshy inner lips up into her tight hot snatch. I licked and probed and sucked as fast and hard as I could while continuing to pinch and rub her sensitive clit.

I could feel Beth’s body starting to quiver above me and started getting confident that I was going to make her cum first. But I couldn’t ignore my own excitement at the same time as she pumped and sucked my manhood as hard and fast as she could too. I tried my best to hold back and just give all my attention to her lovely hot box but I could feel myself weakening too. It was really coming down to the wire for which one of us was going to lose it and cum first.

I think I almost blacked out from the painful pleasure as I felt her body shake hard and her pussy juice start running down onto my face as my over stimulated cock simultaneously burst forth with huge streams of hot sticky cum deep inside her mouth. We both moaned into each others’ genitals, the vibrations making both my cock and her pussy feel even more sensitive and also causing another bout of ejaculation for both of us. We both collapsed on the floor as Beth rolled over on her back beside me and we both just lay there breathing heavily.

I managed to catch my breath enough to raise my head and say “Well?” to my sister.

“Well, what?” she answered teasingly. “You want to know who won and who lost? Who is going to be doing the forfeit? I don’t know. What do you think, girls?” she asked Amy and Carly.

“I don’t know,” Amy answered back. “It sure looked pretty close to me.”

“I think it was a tie,” I chimed up. “We both came at the same time. I should know, I was there,” I explained logically.

Beth had finally caught her breath too. “I agree with David,” she said. “It was definitely a tie. Actually maybe the closest I’ve ever come to a mutual orgasm. So I guess nobody has to do the forfeit, right?”

“Hmm, I’m not so sure about that,” Susie replied. “I’m thinking you both have to do the forfeit.”

“And what would that be?” I queried.
