That night mom was gone for some trip by her office company and I had to ask Laken to join his bed because of the scary nightmare I had.

Other nights I managed myself, but that night I just couldn't.

I wasn't surprised when I woke up the second night to him violently humping the side of my thigh. I let him go for a while, listened to him huff under his breath as he furiously rubbed against me, and then I peeled his fingers from where they were gripping my shirt and slid out of the bed.

I watched him for a minute, observed the furrow of his brow as he humped the mattress where I'd just been laying, and then he rolled over onto his back with a sigh.

His cock, still hard with need, made a tent in the blankets, but he seemed to be done.

The thing is: after he'd cum between my thighs in the van, I'd started to feel a little guilty. I know Laken loves my mom, and I know he hasn't been with anyone sexually since the marriage. So having him cum between my thighs made me feel horribly guilty, and I was trying to make an effort to both keep things from being awkward, and keep him from fucking me in his sleep again.

That meant I couldn't tell him about his problem, and it meant I couldn't indulge in my morbid curiosity, either.

I laid down on the farthest edge of the bed as I could without falling off, and I hoped for the best. The shorts I was wearing were thicker than underwear, but the waistband was loose. And just for that little thrill of excitement, I didn't wear panties.

My loose t-shirt pooled around me, and with my back to Laken.

All things considered, I slept really well. That was, of course, until I again felt an insistent pushing against my ass and pussy, and I slowly roused from sleep to the feeling of Laken humping me from behind. His right arm is under my neck, hand dangling over the edge of the bed, and his left arm is thrown over my waist.

I can feel his breath against the back of my ear, each exhale timed with a slow hump of my ass.

I let him go at it for a while.

He's a heavy enough sleeper that when I finally decide I feel guilty enough to get out of bed, I can do so without worry. He keeps humping me from behind, and I just exist in the moment.

That morbid curiosity creeps up my spine, excitement and arousal boiling in my gut, but I know I need to get up.

I chance a look down just to see, and I find that we must have kicked the covers off at some point.

The window is open, so I can see him hump me a few times in the light from the lamppost outside. Just as I'm trying to make up my mind to get out of bed, the button on his stupid old boxers bursts, and his cock flings out and smacks me right in the clit.

It's then that I realize the loose waistband of my shorts did not keep them up around my hips.

It's exactly what I fucking wanted, but guilt quickly overrides the excitement.

Laken starts thrusting with a slightly faster pace now that it's skin on skin, and his cock slides between my pussy lips and brushes my clit over and over again.

It truthfully isn't as stimulating as masturbating would be, but the simple fact that he's almost fucking me has me moistening rapidly.

I lie there, tense and gasping with excitement as Laken rubs the length of his cock against my pussy lips, but the guilt picks back up again.

Despite my desire to stay here, I slowly start to push myself up and shift away. And it's as I'm shifting away that Laken thrusts again, and his cock buries itself inside of me.

He grunts at the same time I gasp, and he grabs my hips with the arm that'd previously been around my waist and pulls me back down to meet him in his next thrust. I'm more than willing to go.

He's still sleeping. I wouldn't believe it if not for the fact that his pace keeps faltering and his body starts to go limp again. Each time that happens, I roll my hips just to get him going, and then he's back to fucking me slowly.

I don't move at all. I don't kiss him back at first, and I don't move my hips except to get him going again. I let my step-dad use me in his sleep, and I fucking love every second of it.

When the telltale tingling starts to build in my pussy, I start kissing Laken back, and it's like a switch flips.

We go from languidly kissing to full on making out in less than a second, sloppy and fast and more rubbing our mouths together than anything else, but the ferocious nature with which he attempts to kiss me in his sleep makes me so fucking horny.

His thrusts pick up speed, too, and he doesn't even get the chance to cum before my orgasm is rocking me to my core.

I gasp into his mouth and clench around his dick, and the feel of him still sliding in and out of me drives me crazy.

I squeeze my eyes shut tight as I ride out my orgasm, and when it's over, I force my eyes open again to watch him.
