Gold Digger Step Mom Part 5 

"Oh, Marsha - "

My fingers move faster against my throbbing pussy. My name - he called out my name. No, he can't be talking about me. There must be another girl named Marsha at his school. That has to be it. I slowly turn back to the door, staring at the knob, desperately waiting for him to say something else, another name, and yet... I think I want him to say my name again. No! No, I don't!

But yes, I do...

"Oh fuck, Marsha...suck my cock, just like that..." My breath catching in my throat, I watch my hand reach out toward his doorknob. This is a bad idea. I can't do this. This is so wrong! But I can't stop myself gripping the knob and slowly pushing the door open enough that I can see his cock shimmering against the light from his window. My pussy twinges again, and I gently slide a finger inside my folds and twirl it around my dripping fuck hole. "Say it," I moan, then clap my hand over my mouth in horror as I realize I've spoken aloud! I stare at Greg in terror, but he doesn't even react. He must be so lost in his daydream that he didn't hear me. Thank fuck! "S-Say my name, Greg," I moan again, a little louder this time, my fingers pushing into my pussy and tickling the insides. "Say it...please, baby, say it..."

"Oh fuck - oh Marsha - oh - oh Mom!"

As pure white semen spurts from the head of his throbbing cock, my pussy clenches around my fingers and I let out a cry of pure ecstasy. My head snaps back and my back arches as an orgasm rips through me like wildfire, sending my entire body into a seizure of twitching and writhing against his doorframe. As it passes, I slump against the wall, pulling my sticky hand from my panties and panting like I've run a marathon. Holy fuck. That is, by far, the most intense orgasm I've ever had in years. I glance back into his room to see him passed out on his bed, his chest heaving with heavy gasps, his hand still wrapped around his prick. I'm impressed by how much cum there is - his dick, hand, stomach are all smothered in jizz, and it's dripping into a growing puddle on his bedsheets. Apparently he hasn't come like that in a while either. I really should wash those sheets... but I don't want to wake him up and embarrass him by letting him know I know he jerked off. Plus, I can't risk him knowing I watched... I decide to let him sleep and shut his door.

I hurry back to my room and shut the door, my mind racing. I masturbated with my stepson - he didn't know I was there, but that doesn't make it any less wrong. I was so turned on by seeing him jerking his fat cock that I couldn't help myself, and the moment he moaned my name, I was lost. But I'm not turned on by the fact that he's my stepson, right? Surely it's because his was the first cock I've been close to in years. That has to be it.

Well, there's one way to find out.

I pull out my trusty laptop and search "mom son sex" and am shocked and horrified by how many videos show up. Over a thousand! Oh, people are disgusting. I'm humiliated with myself, but I click on the first one that looks interesting, trying to ignore the fact that the man looks way too much like Greg. There's no build-up, no plot, no explanation - it cuts straight to him sliding his cock into her eager, waiting mouth. I try to keep my hand out of my skirt, but I can feel my juices starting to flow again. I shift a little, feeling a pillow underneath my butt brush against my pussy lips and send tingles of pleasure all the way up my body. No, it's not the video. I'm horny in general. I only had one orgasm, and I usually need two or three to please myself. That's all this is.

"Oh, yeah, mom, such that cock - you're so good, mom..."

And there I go again. Before I can even register what's happening, my hand is in my panties, frantically rubbing my clit and fiddling with my fuck hole. I assure myself yet again that it's okay because I'm not masturbating to the video, but deep down I know that I'm lying to myself. Hearing a young man moan 'mom'...ugh. It's so goddamn hot.

"I need you inside me," moans the mother in the video. "Baby, I need your fat cock inside me. Fuck me, baby, fuck me harder than your daddy ever did!"

"Oh, I will, mom. I'll make you cum so hard, you never go back to his dick again."

The video focuses on the mom now, and it's...a bit of a turn-off. It reminds me that it's not ME sucking that young, virile cock. But it's okay - she looks enough like me that if I squint, I can imagine myself gazing up at him with desperate, needy eyes, and my fingers slide inside myself and start fucking me harder than I usually do. I need this. I need to cum.

"Oh, fuck, mom, you're so fucking tight...oh, mom!"

I'm already almost there. I can feel that intense feeling that signals that a good hard orgasm is close. I fast forward a little bit to a scene where I can focus on his cock sliding in and out of that wet pussy. I grab the closest thing I can, a hair brush, and shove it deep inside me, fucking myself as hard and as fast as I can. Just...say it. Say it one more time. Please. I need it!

"Oh fuck - oh mom! OH MOM!"

"Oh, Greg!" I scream as the orgasm explodes inside me. My back arches and my legs slap together so hard that I flip my laptop off my lap and onto the floor. I don't even care. I haven't cum this hard since - well, ever. It takes a full minute for me to come back down enough that my body will finally relax. I lay back against my pillows, panting. Oh fuck. That...that was wonderful.

I change clothes and start cooking dinner, but my mind is racing the whole time. I can't believe what happened. I keep replaying the afternoon over and over in my mind as I season the hamburgers and start flipping them in Mike's prize cast iron skillet. The cucumber in my mouth, rubbing the back of my throat. His eyes when he sees me, widening in shock. His hand around his cock, stroking faster and faster as precum dribbles down his knuckles. My fingers in my pussy, rubbing faster and faster as he moans my name. Even though it's been less than an hour, my pussy shivers and warms at the memory. I scold myself and try to keep my attention on the burgers, but I can't focus. I can't believe I masturbated to my own stepson's moans, let alone that I'm so turned on by the idea of fucking him! Is this a new thing? Has he always secretly lusted after me? I have to find out for sure. I have to know if Greg is really jerking off to me.

And my horny, addled mind can only think of one solution.

********

"Dinner looks great, Marsha." Greg slides into the chair at the kitchen table, avoiding my gaze. "Dad called me a few minutes ago. He said he isn't going to be home until late, so don't wait up."

I'm not disappointed - I'm actually delighted. "He's working very hard to support this family. I'm sure someday you'll work just as hard to support a family of your own." My words are automatic, and mechanical. It's something a responsible stepmother would say, although I'm not sure what I'm planning will let me hold that title for much longer. I slip a plate in front of him, leaning forward enough that my breasts brush against his shoulder. My heart is fluttering with nerves.

I changed clothes after my little encounter earlier. I'm wearing a simple black skirt with darker pantyhose and black high heels that click with every step. I also threw on a bright red camisole with a little more cleavage than I usually care for. I draw my finger along the line of my cleavage, my nail scratching the flesh of my breasts. He turns to smile at me in thanks for the burger, but his eyes lock on my nail for over a second before flicking back down to his plate. This tells me nothing. I have to dig deeper.

"So...how was school today, dear?"

"It was all right. The Algebra teacher was sick, and the substitute didn't know what she was doing. She was too busy flirting with the jocks in the back to do any teaching, so I caught up on some homework." He takes a bite of his burger and chews it slowly. I watch his lips twitch as his jaws move, picturing them moaning my name. I have to find out.

"I'm glad you're keeping up on your schoolwork. It's such a responsible thing to do. You're growing up to be such a strong young man..." I step behind him and begin to rub his shoulder blades, pushing my breasts forward so they rest on the back of his neck.
