I confess that I turned down a drunk, horny teenager begging for sex. I regret it now, but at the time I just couldn't stop wondering if she'd sober up and never want to see me again.

A few years back, I had a job that was far from home and the commute and long hours drained me so much I was nearly falling asleep while driving home. Since my sister lived nearby, she offered her spare room for the days when I was too tired to drive home safely. She and her boyfriend worked night shifts mostly, so I rarely saw them except for briefly over dinner maybe before they left.

One of these nights I took her up on it, they had already gone to work when I got there. I unlock the front door with the spare key they gave me, and walk back to the living room to find my niece and a school friend of hers watching a horror movie. After some brief introductions with her friend, I join them on the couch. Any time I get up and go to the bathroom or to get food and am out of earshot, I can hear them both whispering to each other and giggling. After a while, I fall asleep early on the couch with them still there.

Not long later I wake up, and the both of them have vanished. I get up and call out their names. "We're in the garage," my niece hollers back. I open the door and find them smoking and drinking beer. Not an unusual thing for my sister's daughter; she's always been a bit of a thrill-seeker, and her mom knew about her smoking, drinking and pot. So it wasn't my place to say anything besides a mild "disappointed in you" frown.

NOTE: Drinking age is not 21 everywhere, before anyone accuses me of serving a minor. And in any case, not my house, not my beer, and I never gave them or told them to get one.

Not wanting to be a total jerk, I ask if I can have a beer, too. I sit on the small ledge across from them, my knees up by my chest and light my own smoke. We chat and drink in there for a while until we finish our smokes. The whole time, her friend is keeping kinda quiet. If I engage her in conversation, she blushes and mutters a quiet answer. I just mistake it for shyness, since it's our first time meeting.

The girls are sitting on top of a trunk freezer with their legs crossed. Both of them are wearing loose shorts, but with the mediocre lighting in the garage, the spaces beneath are nearly pitch black. My vivid imagination fills in the blanks, though, and I feel myself swelling in my pants. Being almost 8" and thick erect but tiny when flaccid makes for awkward and painful hardons sometimes. When soft, it'll flop straight down, then as the wood begins, it starts straining to point upwards, to the detriment of the crotch of my pants.

I adjust my legs in a way that shoves my semi-hard cock to the side, not trapped in the downward position anymore. As I'm making the movement, I notice both girls' eyes drop straight to my crotch. I'm not sure how much they saw, but I'm sure it was a show. I pretended I didn't notice their gaze.

We eventually retire to the living room again to put another movie on. More drinking, looser tongues and more familiarity means her friend is finally opening up. The conversation drifts to sex, and they both think it's funny I lost my virginity when I was older than they were. I tell them I've always been shy around girls, and never dated much until after high school. The few I had dated were good relationships, though, so I didn't mind.

Suddenly my niece says "I've always had a huge crush on you." Awkward silence while I think of how to answer that. It's true, ever since she was 13 and started looking at boys, she was looking at me. Being the youngest of my siblings, and with her mother being the eldest, my niece and I are only about 10 years apart in age. As the years went by, it was obvious she had a crush and I didn't do anything to encourage or disuade it, thinking it was just a phase.

On this particular night, I think she and her friend had devised a plan to do something about her desires. That's what all the whispering and giggles were about.

Being a lightweight, I'm pretty well tipsy at this point. I tell her that I think she's beautiful, and if it weren't for the age difference and family relationship, I'd go out with her. The conversation seems to end there and after some silence, drifts back to random things. Around midnight, I drift off to sleep.

A while later, there's a light tugging at my waist. Now if I hadn't been drunk, I think I might've feigned sleep through this. Instead, I startled awake to find my niece in her bra and panties, straddling my knees and undoing my pants. Her beautiful C-cup breasts are barely contained in the lacy cups, and her panties are already wet.

The lights are off, but the moonlight through the windows silhouettes her figure perfectly. Everywhere my eyes look are amazing curves and sexy bits and oh my god, my niece is fucking hot as hell!

She already had the belt undone and the zipper opened, spread to show my boxers and the outline of my rock-hard cock beneath. I can only imagine I slept through some teasing for it to be hard like that.

I tug the jeans together quickly to hide my erection, and glance over to see her friend on another part of the couch quietly. She's laying under a blanket with her eyes closed, but I can tell from her breathing, how red her face is and the squinting around her eyes that she's faking it, keeping her eyes open a sliver. Hoping that I won't see well enough to tell in the dark room.

"Come on, don't be like that. I just want to see your cock," my niece purrs as she slowly gyrates her hips, rubbing her wet panty-clad pussy against my leg. "I swear, I won't do anything else."

"We shouldn't do this," I stammer out. "If your mother found out, she would kill me."

"She won't," she whispered as her hand gripped my cock. Almost as fast as the contact was there, I grabbed her wrists and pull them away and together. This made her lose balance and flop forward on me, her warm breasts falling against my chest.

"But it's not right... we're related," I barely manage to force out of my lungs. At this point I'm finding ways to let her out of this, but god if I wouldn't love to plow her while her friend watched.

Then my drunk brain suddenly thinks, she's not going to take no for an answer. Maybe I should just deflect this and make her pissed off instead. "Maybe if your friend were to do it, it might be okay," I said in as sleazy a way as possible.

It worked. At that point, she cooled off fast. I didn't really think her friend would jump me, she had been too shy at this point, not moving from her vantage point and likely fingering herself under the blankets at the sight of her best friend straddling an older man with a hard cock two inches from her pussy. My niece climbed off me and put her sleeping t-shirt and shorts back on. No words were said at that point, and it was too dark in the room to see her face properly. Since they were sleeping in the living room, I went to the spare room and slept.

The next morning was a Saturday, so no school or work for us. My sister, on the other hand, had an early shift and was out the door early. I came outside for my morning smoke, and the teens are both out there, very quiet. I sit on the porch next to them.

"I dunno about you," my niece begins, "but my head is killing me. I barely remember anything from last night." I raise a skeptical eyebrow as I face her, and she glances quickly at me before looking down again.

"Yeah, me either," I say in a sort of "don't worry, I won't tell" tone of voice. We've never really talked a lot since then, not that I've ever been close with my siblings' side of the family for as long as I remember.

She's now grown into a beautiful woman of 21. We've never talked about what happened that night, though I want to. I want her to know how I still fantasize about that night and what almost happened, and how much I hate my strong morals for turning her down.

While I doubt it, I wonder if somehow she'll read this and pluck up the courage to talk to me about it. And if she was ever interested, I wouldn't turn her down again, but I won't push for something she doesn't want.

Call me fake if you will, I don't give a fuck. I'm not going to drop any details or proof, though I will update if anything should ever happen. I've been thinking of breaking the silence, though I don't know how.
