Story 1 Chapter 5

She keeps rubbing up against me, and I know I'm supposed to be swimming, but I think I might drown us both if I try to swim with her rubbing her pussy against me like that. Her breathing turns a little heavy as she rubs up against me faster, pushing down a little harder.

Naudia is close. She is using me as her own human size sex toy and I can't even tell her to stop. I don't want to tell her to stop. What I really want is to slide that little strip of bikini out of my way, pull my shorts down and slam my hard dick into her tight little pussy. Make her moan my name as she cums on my dick.

Naudia rubs against me again and I push my hips forward, holding her legs to keep her close as I help her rub against me.

"Gavin." She moans softly and this time I do groan unable to stop myself. Fuck my name sounds so sexy coming out of her mouth.

I look around quickly to see where Grant is, he's at the other end of the pool, floating on one of those blow up mat things. Fuck, I shouldn't be doing this. This is his sister, my son's sister.

Naudia's nails dig into my shoulders as she rubs herself against me, harder and faster. I thrust my hips up, meeting each of her thrusts. She keeps moaning softly, each moan going straight to my dick. Fuck. I swear I could cum right here in my swim shorts.

"Gavin." She moans quietly, panting a little. "Please, I need to-."

I lean in and whisper. "It's okay babygirl. You can bite my shoulder to muffle the sound. Just use me baby."

Naudia thrusts her hips a couple more times and I feel her body tense up. She leans in, burying her face in my neck as she bites down on my shoulder. Her body starts shaking as the first wave of her orgasm rushes through her, she moans and even though it's muffled I still hear it. "Oh fuck. Gavin."

I use my hold on her thighs to guide her hips up and down against my dick a couple more times, helping prolong her orgasm. She cries out, biting down harder as her body continues shaking against me.

"That's it babygirl." I whisper, glancing over to make sure Grant is still far enough away from us.

Naudia keeps moaning, and shaking as she comes down from her orgasm. When she finally looks at me, I can't help but groan a little. Fuck she looks sexy. Eyes glazed, face and chest flushed, lips slightly parted. Her chest is rising and falling rapidly from her heavy breathing. Fuck.

Naudia smiles up at me. A cute shy smile. This girl that just used me to make herself cum is going to act shy now. "Do you feel better babygirl?" I ask and she bites her bottom lip, nodding her head.

"Yes." She whispers.

"Good. Do you want to keep swimming?" I ask. Hoping she says yes, but also hoping she says no. As much as I love feeling her soft body pressed up against me, I don't think I can take anymore. I need to take care of my own problem before I explode.

Naudia stares at me for a minute. "No. I'm okay."

I smile at her. "Okay babygirl. I think I'm done too."

She smiles. "Okay."

I walk a little further into the shallow end, making sure she is capable of reaching the bottom, but she doesn't let go of me. "You can reach the bottom right here baby." I whisper and she shakes her head.

"No I can't."

I chuckle. "Fine. I will carry you baby."

Naudia smiles at me, clinging to me. With each step, my hard dick rubs against her pussy, making it very hard to focus on walking. When I step out of the pool, I walk over to one of the lounge chairs and set her down.

"I'm going to go take a quick shower. Let your brother know if he asks where I went."

Naudia bites her lip and glances down at the bulge in my swim trunks. "Okay. Have a nice shower." She whispers, looking up at me with that sweet innocent smile.

She is not sweet or innocent. She is a sexy little tease, and I am in a world of trouble. This is going to be a very long summer, and I am going to have to get some self control. I shouldn't have let that happen and I definitely can't let anything like that happen again. Now if I can just get my dick to understand that.

I practically run up the stairs to my bedroom, I don’t waste anytime making my way into my bathroom. I turn on the hot water in the shower and strip my wet swim trunks off, letting them fall to the floor. The bathroom fills with steam, and I step inside the shower. The hot water feels nice on my cool skin. I stand there under the stream of water for a minute, letting it wash over me.

The feeling of Naudia’s soft, perky breasts pressed against my chest pops into my mind and my dick throbs. Fuck. I wrap my hand around my shaft, sliding my hand up and down a couple of times. Fuck that feels good.

Naudia’s soft moans invade my mind, and I think about what it would feel like to have her moaning under me as I thrust my dick into her warm, tight little pussy. “Fuck.” I groan as I stroke my dick faster. Naudia moan’s my name and I groan loud. I want her so fucking bad.

Her young tight little body, pressed against mine, begging me to fuck her. That innocent look she gave me as she rubbed her little pussy against my hard dick. I stroke even faster. I wonder what she would sound like if I made her scream my name as she came on my dick.

I wonder what she would look like, looking up at me while she’s down on her knees sucking my dick. “Oh fuck.” I groan again. I start thrusting my hips, stroking my dick quickly. I feel my orgasm building quick. “Oh fuck, Naudia.” I growl as the first spurt of cum shoots out. I keep thrusting my hips and stroking my dick, as spurt after spurt of cum shoots out on the shower wall.

My thrusts and stroking come to a stop when every drop of cum is milked out. Fuck. What the hell is wrong with me? I just jacked off to the thought of my son’s sister. I groan, washing off quickly and step out of the shower.

I grab a towel, drying myself off. I wrap the towel around my waist and look in the mirror. That’s when I see Naudia’s bite mark. I guess I will be wearing a shirt at least until Grant leaves for camp. I don’t know how the hell I would explain this to him.

I walk into the bedroom. I find a pair of basketball shorts and a T-shirt. I sigh and make my way back downstairs. I go to the kitchen. I tell myself it’s to find something to cook, but I know that’s just an excuse. I catch myself staring out the window at the pool.

Naudia is sitting on the same chair I left her on. Still wearing the tiny little bikini. Grant is splashing water towards Naudia, taunting her. I see Naudia laughing, shaking her head. Grant climbs out of the pool, and Naudia stands up. She runs behind the chair and Grant squats down, shifting from side to side.

Naudia takes off sprinting towards the house, squealing and laughing. I hurry up and step away from the window. Trying to act like I wasn’t watching them. Naudia runs in the house, giggling. She spots me when she runs into the kitchen.

“Gavin help me.” She squeals, running behind me.

Naudia wraps her arms around me from behind, clinging tightly to me. She presses her whole body against me, and I feel my dick hardening. Shit, now is not the time to get hard.
