I hesitated a little, wondering what time mom was going to get home. In the end, a bare pussy staring at me trumped when was mom coming home. I pulled my shirt off and then bent to untie my shoes and kick them off. I pushed my jeans down and worked them over my feet while I pushed my briefs down, leaving me in just my socks, my hard-on sticking out at her.
"That didn't take long to get hard," she said as she lay there, stroking her shaved pussy with her fingers. "Why don't you come over here and do what you did last time. I liked that." I walked to the bed and crawled onto it, laying down on the soft mattress between her legs. She moved her hand from her pussy as I moved myself close enough to gently lick my tongue up her already wet slit. I teased my tongue between her lips as she spread her legs and used her fingers to pull her full round lips apart. "Ohhhhh yeah. That's it. Tease me right there," she moaned as I licked my tongue up and down across her hard little clit. "Oooooooooooh, that feels so nice."
I continued to lick and tease her sweet pussy, teasing her closer and closer to an orgasm as she pulled and pinched her own nipples. "Oh God. You're going to make me come," she moaned quietly as I teased her clit, flicking my tongue back and forth across it. "I don't know where you learned that, but it's soooo good," she moaned. "Just a little bit more. Just...a....ohhhhh.. fuck, Andy! Here it comes...."
I was surprised at how much juice her pussy leaked out at me, almost squirting out at my chin while I teased her clit. I pulled my face from her pussy and crawled up between her legs, more than ready to plunge my hard-on into her. She reached her hands for me and pulled on my hips, barely giving me time to aim my mushroom head at her wet lips. I slid easily into her leaking pussy, drawing a gasp of pleasure from her as I drove deep into her. "That's it. Fuck me Andy. Fuck my hot little twat!"
"Uh huh," I grunted as I started to plunge in and out of her, driving my cock fully into her until our bodies banged together. Each time I slammed into her she gasped a little more, my strokes clearly having a huge effect on her. In and out I thrust, watching her little boobs wiggle on her chest as we pounded together. She lifted and spread her legs even wider, encouraging me to drive even deeper into her. "Shit. I'm gonna come," I grunted as my body started to give me that warning signal.
"Do it," she gasped as I continued to pound into her.
It was only a few more seconds before my body could hold back no more. My body jerked and drove hard into her as I went rigid, my dick pumping a huge shot of cum deep into her pussy. I held myself over her, my body jerking and spasming with each new gush of cum flowing into her. I finally sagged down and lay on top of her, feeling her tits pressed to my bare, sweaty chest, her nipples sliding slightly on my chest as we both panted for breath.
"Oh damn that felt good," she said softly. "I should have started fucking you a long damn time ago."
"Yeah. I'm thinking the same thing," I answered, still trying to catch my breath.
"We better get dressed before mom gets home," she whispered after we had been laying together for almost five minutes.
"Yeah. Probably," I agreed, pushing off of her, my softened dick having slid out of her some time ago. I picked up my clothes and padded naked down the hall to my bedroom. I paused at the door, looking at the door handle, and the pair of frilly women's underwear hanging on the doorknob. I looked around in confusion and then pulled the panties off the knob and walked into the bedroom, closing the door behind me. I laid my clothes on the bed and looked at the panties. They were definitely too big to be Tammy's, and the crotch was definitely wet. I'd say they were mom's, but how would they get on my doorknob and why would they have a wet crotch? I lifted the panties to my nose and smelled the crotch. Yeah, that was definitely pussy juice. There was only one conclusion I could draw. Mom had been watching and we hadn't seen her. How else would fresh pussy juice covered panties find their way to my doorknob, unless Tammy was playing another prank on me.
I walked to my dresser, pulled out a pair of athletic shorts and pulled them on. If mom had been watching, then she was home. I padded down the hall barefoot again, walking down the stairs as silently as I could. I wound through the living room to the master bedroom and stopped. I leaned my ear to the closed door and heard sounds. I could hear what I thought was a vibrator, but it was too loud to be that. The moans that were associated with it made me think that it was some kind of great big vibrator. Of course, that also meant that mom WAS home and maybe had been watching us. But why would she watch us having sex? I mean she has dad and they clearly can spend hours having sex if they want too.
I gripped the knob of the door and turned it slowly. I knew if she caught me, I'd be dead meat, but my curiosity was getting the better of me. I pushed the door open a crack and looked in. Yeah, mom was definitely home! I could see her reflection in the full length mirror on the far wall. She was sitting or straddling something that looked like a small half barrel, completely naked. I could see the curly brown matt on her pubic mound and her pussy lips spread around something flesh colored on the top of the half barrel that most certainly was vibrating. Her eyes were closed, and she had both her big tits in her hands, her fingers twisting and pulling on her nipples while she held the big soft mounds up. She rocked herself forward and back on the device, moaning softly as it did whatever it did inside her.
God it was hot! I'd seen her partly naked on Saturday night, but nothing like this. I could already feel my cock growing in my shorts and despite my better judgement, I pushed the front of my shorts down and pulled out my hardening dick. I stood at the door, watching her body be pushed closer and closer to climax while I stood, peeking in the door, stroking my cock. I knew I shouldn't be, but I couldn't help myself. She looked so damn hot sitting on that thing, getting closer and closer to orgasm.
As I watched she leaned further forward, leaning toward the mirror, pushing the vibrating device up against her pussy, her mouth opening in a long gasp. I could see her body start to shudder and twitch, as her orgasm started to wash over her. Suddenly her body jerked, her hands dropping from her tits to hold herself up from falling onto the floor. As she leaned forward, I could see her ass and then her pussy, a flesh colored protrusion sticking up into her pussy. She started to lift and lower herself, dropping hard down onto what I could now see was a vibrating dick. Up and down she slid on it, pumping herself up and down the shaft, her ass bouncing against the machine each time she thrust herself down on it. I stood there, stroking myself, my mind picturing her ass bouncing up and down on me, my cock sliding in and out of her pussy. I could hear her moan and gasp as her body trembled and jerked amid her up and down thrusts.
"Oh fuck," I gasped as my body responded to my own strokes. I hadn't even realized I was so close, but there I was, standing at the door of my stepmom's room, squirting cum on the door, the doorframe and the gap in the door while she climaxed on the machine she was riding.
I closed the door, wondering what the hell I was going to do now, wondering if I had been too loud, wondering how the hell anyone could explain cum dripping down the door and door frame. I pulled my shorts off and quickly wiped as much cum off as quietly as I could and then ran as quietly as I could back to my room.
I sat on my bed, my heart pounding as my mind replayed the view of her ass bouncing up and down and the reflection of her big soft tits swinging wildly in the mirror. I couldn't believe that my dick was already getting hard again from just thinking about it, how she looked, how she might feel. I mean she was my step-mom. It wasn't something I should be thinking about, but then fucking my sister wasn't exactly something particularly kosher either. I lay there, thinking about how sexy her body looked, stroking my dick even harder. The knock on the door startled me back to reality. I looked around and quickly pulled the blanket of my bed over my legs and hard-on as the door opened slowly.
I saw my mom stick her head in to see me and then push the door open a little further to slip through. She closed the door and quietly latched it behind her before turning to face me. She was dressed in a short satin looking robe, her nipples clearly poking the front of the robe out. Her long sexy legs were bare, sticking out from the extremely short robe, barely long enough to cover her round butt cheeks and her pussy. She walked over and sat down on the edge of the bed, her hip inches from my own. She reached out and lay a hand on my covered leg. "Andy. I think we need to have a talk," she said quietly.
"Yeah Mom?" I asked as innocently as I knew how.
She looked at me with a small frown. "Don't play innocent with me. I know you were spying on me a little while ago."
I looked down at the bed, knowing I was caught. "Yeah. Sorry. I didn't mean to. I mean, I came down to see if you were home, and well, I couldn't resist."
"I suppose it was inevitable. I meant to leave you a message, but not the one you apparently received."
"A message?"
"The underwear? I presume that was why you were looking to see if I'd gotten home."
