Iâm going to hell. Thatâs it. Thatâs all there is to it.
My cock grew with every step Pen took up that ladder. I couldnât help it, watching her juicy ass, imagining how those globes would feel in my hand as I slammed into her from behind.
Shit. I squeeze my eyes shut, trying to push those images out. That was an hour ago and I still canât get the flashes of temptation out of my head.
Weâve finished eating and are about to enjoy the private waterfall when the clothes start coming off. Lord help me, a man can only take so much.
Pen removes her tank top and cut-off shorts, revealing a black bikini that leaves little to the imagination. Jesus. I really need to talk to Mary about what sheâs getting Pen.
Sure, Iâm enjoying the view now, but I canât help and imagine the college boys that will drool over Pen when she takes this two-piece with her.
The kids squealing and splashing pulls me from my murderous thoughts. They both stay on the edge but Pen, being the adventurous girl she is, heads straight for the fall itself. Sheâs about ten feet in when she lets out a yelp, going under not two seconds after.
Before I can even think, my legs jump into action. Iâm sprinting toward her, pulling her into me as soon as Iâve reached her flailing body.
âAre you okay? What happened?â My hands roam her, trying to see if something bit her.
Instinctively, her legs wrap around my waist as I haul her closer to me, pressing my large hand against her back and causing her chest to rub against mine. I have to swallow a groan as her hard little nipples rub on my bare chest, the small contact sending blood rushing south.
Abort. Abort. Abort. A voice inside is telling me to put her down, but my limbs donât obey.
âMy ankle. I rolled it. I guess my foot mustâve gotten stuck between the rocks.â Big doe eyes blink up at me, the action causing beads of water to cascade down her cheeks.
My heart is pounding a mile a minute at the thought of her being hurt, and I wonder if she can feel how much it affects me.
âFuck,â I hiss before pressing my lips to her forehead. âYou scared the shit out of me, Pen.â
She wraps her arms around my neck, all while biting her bottom lip and releasing a soft whisper that has my cock hardening in a flash. âSorry, Daddy.â
I close my eyes and suck in a sharp breath. âWhat are you doing, Pen?â
My cock is fully awake now, begging to get out of my thin swim trunks and rub all over her sweet heat. It would take seconds to slide that tiny triangle of fabric to the side and shove myself deep into her cunt.
Just then, my length twitches against her folds, her eyes going wide at the realization.
Iâm about to move her so her core isnât directly on my erection, but she shakes her head no, gripping onto me tighter.
My wicked little girl looks over her shoulder, making sure the kids are occupied and completely unaware of whatâs going on beneath the water. Christ, this is not good. I should stop this right now.
âPenelope,â I warn for what feels like the millionth time. This is so wrong. Sheâs my niece. Sheâs so damn young. If Austin were alive and saw me holding her like this, heâd fucking murder me.
âWhat? Youâre not doing anything wrong. Youâre just taking care of me. Donât you want to take care of me?â She begins to rub herself on my length, all while Iâm frozen like a statue, save for my ticking jaw.
Iâm unwilling to be a participant in this sinful act, but damn if I donât enjoy her little whimper when her clit hits the top of my aching cock. She keeps rocking against me as my fingers press deeper into her full hips before trailing down to her ass and squeezing. God, they feel even better than Iâd imagined.
I need to stop. This shit canât go any further. âPenelope. We canât do this.â
She lets out a little moan and I practically come in my trunks. âThereâs no we. Youâre not doing anything wrong, Uncle Jack. Itâs all me.â
I close my eyes and take in a deep breath. Anything to keep me from rutting into her like a wild animal. Just then, her hand snakes into my shorts, pulling all of me out. She gives my dick one hard stroke and I swear I see God.
Using the tip of my cock, she slides her bikini to the side, rubbing the fat head up and down her slit.
Fuuuuuck. That feels good. Too good. With a little thrust, Iâd be inside. No! Iâm fighting myself when she lays my length flat against my stomach before pressing her soft folds against my bare flesh. Pen is grinding herself up and down the shaft and I know Iâm about to make a mess.
âPenelope. No,â I grit out, low enough for just her and me to hear. A quick glance toward the kids shows me theyâre still busy collecting stones along the shoreline.
âJust a little more,â she whines, pressing herself harder against me with slow deliberate grinds pulling the sweetest sounds from her lips. âAlmost there, Daddy.â
An animalistic rumble comes from somewhere deep inside me. Iâm a weak man. Her words slay me. She wants me. She needs me. Her daddy.
In that moment I know. I want to be the only man to make her feel good. The only man to ever make her whole.
Even with this realization, I know Iâm not supposed to touch her. âI canât touch you, Princess. You know itâs not right.â
Pen presses her body flushed with mine, her lips brushing against my neck before her words wreck me once more. âItâs okay, Daddy. Donât move. Let your little girl take what she needs.â
Jesus christ. I know I must be leaking because, holy fuck. What can I say to that?
Before I can say anything in response, Pen rubs her slick folds up and down my length, my jaw clenching so tightly my teeth are about to crack.
Despite how fucking good this feels, I donât dare move; I donât dare breathe. My hands remain on her hips, unwilling to move back to her ass for fear of angling her just right.
I canât do that. I canât slide inside her. Itâs wrong. This is wrong.
Her words keep echoing in my head. âDonât move.â
My mind might not agree with this, but my body has taken her order as gospel.
Iâm doing the best I can to comply, but I know I canât hold out much longer. Thatâs a line I wonât allow myself to cross, even if I have to leave her in the water with an injured ankle.
Better that than fuck her right here and now.
Iâm warring with myself when she begins to shake in my arms, shuddering against me while her whimpers come out choked. Her climax hits her not twenty feet away from her oblivious brother and sister, and in that moment, I couldnât be more thankful for the murky water.
As sheâs biting down on my shoulder, coming down from her high, a wave of rage hits me. Iâm one sick fuck. Despite knowing this was wrong, I enjoyed every bit of it. Hell, given a few more seconds, I know I probably wouldâve thrown all morality out the window and fucked her raw.
This is all so damn sick. Iâm her damn guardian. Iâm supposed to be protecting her, not corrupting her.
Pen is limp in my arms, her climax having ebbed. Needing to right this situation, I carry her bridal style while tucking myself back in and making sure her bottoms are in place. I need to get us out of the water.
As soon as weâve reached the shoreline, I place her on a smooth rock and head inside, not even looking back, rage and shame filling every cell of my body.
I need to get away from her and take care of this raging hard-on before I do something that will make me hate myself more. What Iâm about to do now is bad enough. Thereâs no doubt sheâll be front and center in my mind as I splatter all over the shower walls.
Like I said before, Iâm going to hell. Thatâs it. Thatâs all there is to it.
