Chapter 2
Denise and I walked to the beach, keeping away from the camp fires and people who mingled together in the darkness. We walked until we were far away from everyone and only the moonlight illuminated the way.
We talked about everything, but every time I tried to ask Denise if she was still a virgin, the subject somehow changed.
"Hey, let's go for a swim," Denise said, then pulled her sweater over her head. In the moonlight I could see her firm, well-shaped tits with the dark brown nipples against tanned skin. There was a sharp line where her bikini blocked out the sun. I watched quietly as she unfastened her jeans and pulled them down her legs.
"Aren't you afraid that someone will see you?"
"Look around, dummy! There's nobody here but us. Even if someone does come around, so what? I've got nothing to be ashamed of. Hell, I've got a good body and I know it. So do you, but you're such a tight ass that you never flaunt it."
Then, standing naked in front of me, Denise reached out and started to unbutton my blouse. I grabbed her by the wrists and pushed her hands away. "If you don't mind, I'll undress myself."
Once we were both naked, Denise rushed into the ocean. I watched the pale moons of her ass as she ran and wondered if anyone had ever shoved his prick between them. Her tits bounced as she ran into the surf, then dived head first into a wave. "Shit," I mumbled under my breath, then followed.
We swam together for a while, then body surfed to shore. After swimming out and surfing back three times, Denise and I were both ready for a breather. We went on shore and I put my clothes back on immediately. Denise said she would wait until she was dry before putting her clothes back on.
"You're such a tight ass," Denise chided. "Hell, you don't even like being nude in front of your own sister. Damn, that's really ridiculous. You know that, don't you?"
Before I could answer we heard a man's voice coming from the darkness. "Well, well, well! What do we have here?"
"Get your clothes!" I hissed to Denise. She looked at me and shrugged her shoulders, causing her tits to rise and fall slightly.
"Who are you?" I asked. Then the man stepped closer so we could see who it was. It was Mike, a neighbor Denise and I sometimes babysit for.
"Don't get nervous," Mike said, moving closer. "I'm not going to hurt you. Though it does surprise me to see you," he said, nodding toward Denise, "in the buff."
Mike sat down between Denise and I. He stared at Denise's naked body and I could only feel embarrassed.
"Like what you see?" Denise asked.
"Very much." Mike reached out and tweaked Denise's nipple and she pushed his hand away.
"Looking is okay, but touching is definitely out of the question. What would Marilyn think?"
"Why do you have to bring up my wife at a time like this?"
"Why not . . . you horny bastard!"
Mike and Denise started wrestling and, during the struggle, Mike got Denise's hands behind her back. I would have done something, helped her if I could, but Denise just kept laughing through the whole thing and it didn't take a hell of a lot of thinking to figure out that she didn't want or need protecting.
"Stop it, you lousy creep! This is rape!"
"It's not rape yet, but it's going to be!"
Mike reached for me but I backed away and shook my head. He just shrugged his shoulders and grabbed Denise's shirt. Still holding her hands behind her back, Mike tied her shirt around her wrists. For a second he had to release his grasp to tighten the shirt in a knot and I noticed that Denise kept her wrists together. Whatever would happen, she wanted it to happen.
"Don't! Please!" Denise said, giggling slightly.
Mike stood up and pulled his pants down to his ankles. Then, sitting down in front of Denise, he grabbed a handful of hair and forced her head down. His prick was already hard as iron, standing straight up from his crotch. Denise's mouth opened as her head was forced down and she captured Mike's cockhead between her lips.
"Ohhhhhhh!" Mike groaned, feeling his prick get heated by my sister's mouth. "Suck it, you young slut!"
Mike pushed Denise's head down and she took every inch of cock she could. Finally, with his cockhead pushed against the back of her throat, Denise had taken all she could. I could see Denise's lips moving in a sort of chewing motion as she tantalized Mike's cock. Her tongue flicked around his prick, occasionally puffing her cheek out.
"That's right, cunt, use your tongue," Mike said, leaning back on his elbows. He no longer had to force Denise to suck his prick; she was doing it because she wanted to.
I stared at Denise's lovely face as she bobbed up and down on Mike's cock. Her cheeks puffed out as she pushed down, taking the cock deep into her mouth. Then her lips puckered out and her cheeks drew in as she pulled up, taking his cock out of her mouth to lash at the cockhead with her tongue. I just sat there, not five feet away, and stared in amazement at the look of sheer lust as my younger sister, with her hands tied behind her back, sucked cock.
"Nnnuuuggggg!" Denise gurgled, tossing her head up and down on the long, thick cock. Strange slurping sounds came from her mouth as she sucked on Mike's prick and I couldn't help but wonder what it would be like to wrap my lips around a cock and taste that mysterious meat for the first time. Again, as before, I could feel my pussy juice begin to flow and my clit tingle. If only I had the courage to let a man know that I wanted to fuck ...
"Damn, you give good fucking head for such a young girl," Mike said, running his hand over Denise's naked back. "That really feels great."
In response to Mike's compliment, Denise bobbed her head faster on his cock. She whipped her head up and down, working her lips and tongue over every inch of cock she could. I watched as Mike's balls, tight in their ball sac, suddenly pulled up tight to the base of his cock.
"Ahhhhhhhhh!" Mike groaned, squeezing his eyes tightly shut. "Uh! Uh! Uh!" he said as the spurting jets of come filled Denise's mouth. She kept bobbing on his prick even as he came. Some jism oozed out of the corner of her mouth and trickled down the shaft of his cock, finally sticking to his balls. Denise finally released his cock from her mouth, turned to me and smiled. Then, with a look of supreme satisfaction, she swallowed his come with an exaggerated gesture, letting me know exactly how much she loved the stuff.
"Fucking A! I really needed that," Denise said to me, then bent down and licked the come off Mike's balls. She wiggled her hands free and then rolled away, her chest heaving for air. Mike just stayed on his back, eyes closed, a strange, satisfied smile on his face.
"You're such a tight ass," Denise murmured, then drifted off to sleep. Mike, his pants still around his ankles, fell asleep alongside of Denise, leaving me there to wonder just what the hell I was going to do with my life and the itching in my cunt.
