I don't know what made me do it, but I sure as hell can tell you now I regret it. There's something uncontrollable about a 19 year olds desire to cum. Makes you do unbelievable things that seem like such good ideas. Until that post nut clarity hits you like a hammer.
I was jacking off in the house, my usual when home alone. When the WiFi crashed, PornHub down, cock in hand. What the hell was I supposed to get off to now, I was so close.
I burst out of my bedroom naked and erect. Heading to my parents room I'd hoped to find some secret stash of my Dad's old porn mags, something, anything. I pulled open the wardrobe, nothing. Dug through the drawers, nothing. Under the bed, nothing. I stood naked in my parents bedroom, dick in hand, desperate for something to jack off to. My eyes landed on the laundry basket. That's when my problems started. Placed on top of the pile, as if beckoning me, lay a red lace thong. Tantitively enticing me. No. I couldn't. Could I?
Fuck it. I grabbed my own Mother's worn panties from the laundry basket. My dick strained harder as I picked them up, uncontrollably picturing her in them. Fuck, what a slut she'd look. Mom had a curvy figure, large tits that were usually fighting to burst from her dress. Wide hips that I imagined would have held this thong up high on her waist, pulling it deep into her thick ass. I furiously started pumping my now throbbing cock at the image of my own Mom wearing nothing but this thong. Without a moments thought or hesitation I buried my face into the crotch of my own mother's worn panties.
'Fuuuccckk.' I couldn't hold back as I inhaled her scent. The thought of her pussy eating these panties up only hours before brought me to the edge of orgasm.
Laughter filled the room and sheer terror made my heart stop. I spun to face the door, panties still held tight to my face. My step-sister's. Both stood in the doorway, both pointing their phone cameras directly at me. Both stood only wearing a tight cropped top and panties themselves.
The feeling of terror and embarrassment, mixed with the sight of their petite bodies, all whilst still inhaling my mother's scent. It was all too much. I blew my load immediately. Shooting rope after rope of thick cum across my parents bedroom carpet, an orgasm so intense my knees grew week and I had to drop to the floor as the last shots of cum dribbled out the end of my cock. My groaning orgasm soundtracked by my sister's now uncontrollable cackling.
I stayed there for a couple of seconds as my thoughts and breath caught up with me. My life was over. Who knew what my sister's would do with that video, showing Mom would be bad enough. But if anyone else saw that? I would never live that down for the rest of my life. As soon as some strength returned back to my legs I ran to my bedroom and shoved some joggers on before heading to confront my step-sisters.
I knocked on the door to their shared room before opening. My sister's were twins. Petite, blonde hair blue eyes. They always wore matching clothing, from morning till night. And more often than not it was the skimpiest, tightest clothing they could find. They loved to flaunt their slim figures, small tits always perky despite never wearing a bra, nipples usually poking through their sheer t-shirts. Small round ass either poking out from beneath their hot pants or tightly wrapped in skin tight lycra.
They were both laid on their front, on twin beds, legs swinging in the air as the giggled at their phones.
'Fuuuccckk.' I cringed at the sound of my own orgasm.
"Hey." Looking at the ground as I spoke, nervous to catch their eye. "What're you going to do with that video? Please don't show anyone. Please don't tell Mom."
"What video?" Lisa spoke first. "I've no idea what video you could mean? What about you Laura?" She looked at her sister to her left, trying to hold back more laughter.
"I don't know Lisa, I guess he'll have to be more specific." They both looked up at me smirking.
"C'mon. You know what I mean. Please. The video you just took in Mom's room. Of me y'know" I felt as though I was shrinking from embarrassment. "Please don't make me say it."
"Oh you mean THIS video." Lisa swung her phone around to face me. I saw myself in full HD. On my knees. Cock twitching in the air, pathetic final spurts of cum falling to the floor. Mom's panties held to my face with one hand, other uselessly trying to shield myself from the cameras. "I dunno. I quite like it, I might keep it."
"No please just delete it and we can forget all about this." I desperately pleaded.
"But maybe we don't want to forget about this?" It was Laura's turn to join in. "Maybe we want to vividly remember our pathetic brother's ruined orgasm. Jerking off in our Mom's room."
"While sniffing her thong." Lisa chimed in.
"While sniffing her thong, can't forget that bit." They glanced at each other before Laura continued. "But... I suppose if you wanted. We could keep this video strictly for our urmm... personal use."
