“I knew she was getting horny and wanted to masturbate along with me, but since it was my challenge, I figured I’d give her a dare to remember.”
Elsie then leaned in closely to Brie and said with a smirk. “I told her, ‘I dare you to let me go down on you.’”
Brie gasped, “You were gonna eat out your sister?”
Elsie crossed her arms, “She was giving me so much shit about it being wrong, I was like, I could do it. It’s not that big of a deal, right? It’s not like I can get her pregnant. She was giving me something to prove, and I was up for the challenge. I was sure she would give in, but she’s such a chicken. She said ‘No way!’ and then suggested, ‘What if I just masturbated, too?’”
“‘That’s not the dare,’ I insisted.
“‘But I’m not a lesbian,’ she whined.
“‘Neither am I. You can just close your eyes and pretend I’m some boy instead.’
“‘But you’re family.’
“Finally, I was like, ‘Fine, you don’t have to do it, but you’ll lose the game if you don’t do the dare.’
“She said, ‘So what? It’s just a dumb game.’
Elsie frowned at Brie. “I guess she had me there. I didn’t have anything else. She called my bluff, so I backed down. But I still hadn’t cum yet, and I know Mallory still wanted to, too. So I thought quickly and said, ‘Fine, you don’t have to let me go down on you, but, you have one last chance. If you don’t want to lose the game, then you have to do whatever I say next.’
“Fine with me,’ she replied. ‘I don’t have to do anything, and I don’t care about losing the game.’
“I turned on my flashlight and pointed it at her. ‘I dare you to fuck yourself… with your flashlight as a dildo.’”
“OMG, what did she do?” Brie asked.
“She giggled in, like, a bashful kind of way and shied away from the light. I didn’t get it, at first, but then she nodded and said, ‘Okay, but if I do this dare, then you lose the game. And I’m going to use this instead.’ Then then she leaned over me to open the drawer of her side table and pulled out this big rubber cock!”
Brie was dazed. “Holy shit, Mallory has a dildo?”
“I know!” exclaimed Elsie loudly, before she looked around and brought her level back down. “She said Mom gave it to her when she turned 13, after she got the sex talk. Mom said she could use it until the right boy came along.”
Brie was in awe. “Wow. What did it look like?”
“It was smooth on one end, like a tube full of glittery, purple jelly, and on the other end, it actually looked like a cock, like what Oliver and Hunter had, but definitely a bit bigger. Probably bigger than your dad!”
Brie blushed, thinking back to the feeling of her father’s cock expanding within her. She couldn’t imagine something being bigger than that.
“Sorry,” Elsie said, “I probably shouldn’t just say stuff like that to you.”
“Talk more about the dildo,” Brie evaded.
“I was kind of surprised Mom got her such a realistic-looking sex toy. It was flexible, bendable, but stiff at the same time.”
“So, did she do the dare?” Brie asked, her voice cracking somewhat.
“Yes! Mallory reached down and started sliding it up and down her crack, getting it all wet from her pussy. She started moaning right away. She was really in heat. I had my flashlight on her now, and I watched as the side with the cock split her plump lips open and got all slippery in her juices. I could see them sticking and glistening off of the dildo. It kinda looked like her pussy was giving it a kiss.
“Then, once it was all slick with her girl-cum, she lowered it down to her hole and placed it at the entrance. She bit her lip and gave it a push, and it went inside. We both gasped as it did. Hers was in pleasure and mine in wonder. Slowly, her pussy got acclimated to the size, and made the whole thing slick for each inch it pushed inside of her. Finally, it bottomed out and she whispered, ‘It’s all the way in.’ A little less than half was sticking out of her.
“I suddenly remembered that I could still masturbate, too, and I immediately started circling my little clitty with my finger again. Mallory started slowly pumping her toy in and out of her, and moaned into my ear.
“I turned toward her and wrapped both of my legs around one of hers and wedged my hand into my cunny crack. I kind of thrust my hips at her and the motion slowly inched me closer and closer to her. Soon I had buried my head into her neck and was mewling uncontrollably.
“Mallory whispered to herself, ‘Fuck, I can’t believe I’m letting my little sister watch me fuck myself with this dildo.’
“‘Why is this so hot?’ I moaned into her neck.
“‘You know why, Els. Because it’s wrong. You’re not supposed to like watching your sister play with herself. It’s dirty because we’re related, yet you’re watching me split my pussy open and fuck myself with this dildo. It goes against nature for siblings to have sex and that’s what’s making it exciting.’
“I was already primed from jilling off before and her naughty words were enough to finish me off. I felt the orgasm rushing from deep within me, and it exploded out through my clitty. ‘Fuck, Mal, I’m cumming,’ I cried, and reached over and hugged my sister close, feeling her warm tits against my arm. My thrusting grew wild, and my mound crashed against her hips sending waves of pleasure up from my pussy.
“I moaned as softly as I could while my orgasm seared through my body. I pressed my juicy cunt against my own sister’s bare thigh, smearing my cum onto her virginal body. I kissed my way up her neck and to her cheeks.
“I probably would have kissed her lips, but all too soon, I began to calm down. The aftershocks fluttered through me, and it slowly dawned on me that my experience was nearing its close. I knew I was going to have to go back to my bed again, but I intended to lay there next to her as long as I could.
“I sighed in satisfaction and watched Mallory pumping the fake cock more rapidly, more intently. She grunted more urgently each time she speared it speared into her. It was gliding smoothly within her now, in and out. I could hear her juices sloshing. While she frigged herself, she turned to me, eyes just slits and a dreamy smile on her face. She said softly, through her groaning, ‘You lose the game, Els.’
“I couldn’t help but smile. She was right. She fucked herself according to the dare, which meant I had lost. I didn’t say anything. I nodded in acceptance of the defeat. I just watched her pump the sex toy in and out of her pussy and caressed her nipples with my hand. She didn’t care that I was touching her so closely anymore. But then she said something I really wasn’t expecting: ‘I dare you to use the dildo on me.’”
“Whoa,” Brie croaked out, barely a whisper. Her throat was dry and were eyes were wide.
Elsie smiled at Brie’s intense interest. “I couldn’t believe she said it. I said, ‘I thought the game was over,’ and then regretted it. I thought she would take it back.
“She shrugged and sighed, ‘It’s still a dare.’
“I immediately rolled on top of her and slid down her body to get between her legs. She moved her hands away and the dildo started to slip out of her. She was so wet and tight that her pussy was just squeezing it right out. I quickly grabbed it and pressed it back into her. She whined aloud as she was penetrated by something beyond her own control for the first time in her life. I had to shush her again, because I thought I could hear shuffling outside, and I was afraid that Dad might come check on us again.
