The room fell silent, with Izzy standing at the doorway, frozen still and what she had walked into, and me, frozen with my engorged cock in my hand, pointed at her, laying on her sisters bed. I watched as her gaze moved down slowly from my face, down to what has happening below, her expression of shock deepening, and her mouth opening wider. It wasn’t until her eyes then moved towards my laptop screen, with a looping video of her sisters face getting plastered with the stranger’s cock that was now throbbing right in front of her, next to which was an image of her in a bikini, that she let out a yelp to express her shock at the scene in front of her.
“Whaaa, Whoo, Huuhh-”
“I’m your sister’s friend, she’s letting me stay!” I yelled out urgently, to try and calm her down and not freak out and think her sister’s house had been broken into.
“Oh..,” she replied, somewhat reassured by this. I had never met Izzy before, only masturbated to her Instagram pictures, and whatever her sister would send me. She was wearing a striped pale blue clop top, and a short high waisted tight white skirt. From the way her big breasts sat in her top, I could tell she wasn’t wearing a bra. Having her stand in front of me like this, as unexpected as it was, was proving to be quite exhilarating, resulting in my cock twitching again in my grip. This seemed to be a reality check for her, as if to bring her back from her daze to what was happening, as she yelled, “What the fuck are you doing dude?? Gross! And what are you watching? Oh my god!”
“Fuck, I’m sorry! I didn’t think anyone was coming home,” I replied sheepishly, but still holding onto my cock, and making no attempts to put it away.
“Why do you have a picture of me up? I don’t even know you! And is that.. oh my god, is that my sister? What the fuck, you’re disgusting!”
“Look I’m sorry ok, I didn’t expect to be walked in on!”
Izzy looked at me skeptically. “Really? Then why was the door open? You did this on purpose didn’t you? Fucking perve!”
“Yeah, but, I thought it’d be your sister coming home, and it wouldn’t have been that weird for her ok, just stop judging!” I replied, a little annoyed now.
“Not that weird? You’ve got a picture of me there too you weirdo! How fucking old are you anyway? Gross!”
My annoyance grew. “I’m 30,” I replied, now actively stroking my cock again whilst looking straight at her. “If it’s weird, you could just leave.”
Izzy paused and fumbled her words for a moment.
“I’m not gonna stop, I’m way too hard, so if you’re grossed out, just leave,” I pushed, looking to gauge her reaction. Her brattiness had sparked my renewed vigour as I slowly stroked up and down my length. I watched her face as I stroked, her eyes fixated on my hand moving over my cock. “You can’t seem to take your eyes off it anyway.”
“I.. I.. No, you should stop!” Izzy mumbled, still staring.
“You like watching this old man stroke his cock in front of you don’t you?” I growled, now more aroused, at her staying.
“No! Gross! Stop..” Her words trailed off as she had to lick her lips to clear the involuntary mouth watering response she was having whilst watching. I had been edging myself too long and had worked myself up into a bit of a mood, and her responses were driving my over the edge of being able to restrain my primal urges.
I stood up, lifting on leg up onto the bed, and slowly stroked the length of my shaft, as Izzy stared, mouth open, as if transfixed.
“Come here,” I instructed, directing her towards my cock. She froze and nodded no hesitantly, Her brattiness had subsided, almost as if mesmerised by what she was watching. “Come here so I can fuck your throat,” I growled.
She walked slowly towards me, and as she neared my reach, I grabbed her arm and threw her over the edge of the bed, bent over it, and her letting out a little yelp of surprise in the process.
“You never post pictures of your ass on insta, so you’re gonna let me stroke to your ass now. Take off that skirt,” I instructed.
“Ew! No! You gross old perve! AH-” Her being bratty again was met with a firm slant to her ass over her tight skirt. I continued to stroke as I spanked her again. “AH! Ok ok! Stop! I’ll take it off!”
I stepped back and watched as she slowly unzipped and pulled down her tight little skirt, revealing her pink lacey panties, scrunched up between her round cheeks.
“So that’s what you’ve been hiding from me huh?” I asked as I stroked more vigorously over her exposed ass, spanking her as I did. “You like having and old man stroke his cock over your young slutty little ass?”
“Noo, I want you to stop..,” she moaned softly into the mattress, as I hovered over her ass, groping and spanking it whilst furiously masturbating over her.
“Turn around,” I instructed. Izzy slowly obeyed, looking a little nervous as she did. I moved closer to have my throbbing veiny erection right over her face. “Open your mouth”
She looked away hesitantly. I was now acting purely on primal instinct, and couldn’t hold back any longer, so I grabbed her by her hair, and made her look up at the veiny monstrosity terrorising her. As she looked up at that thick veiny cock nervously, I slapped her face with it, on one cheek, then the next, making sure to get some precum on her face.
“Eww! My god! Gross! It’s so hard and warm! And gooey!” She moaned.
“Yeah, you like that don’t you? You’re gonna be a good little slut for me just like your sister aren’t you?”, and before she could answer, I shoved my cock into her mouth, muffling her answers with my throbbing cock, moaning out loud as I did. I began to thrust into her mouth slowly, deeper with each push, easing her into taking more of me in her. Her reluctant moans eased into submissive unexpected sounds of pleasure as she eased her throat into being filled by me.
“Good girl,” I encouraged, “I knew you’d like choking on this old man’s cock.”
I thrust deeper still, and hearing her choking and gagging on my length encouraged me to thrust faster and harder. I took a moment to relish what was happening, beyond my wildest fantasies. There I stood, completely naked, with the door still open, in my friends spare room, her younger sister kneeling beside the bed in front of me, my hand holding her by her curly blonde hair, guiding her as she stroked my cock with her throat. I moaned and grunted as I continued to thrust, encouraging her by telling her what good little slut she was being for my cock. I was so lost in the pleasures of fucking Izzy’s throat, that I didn’t hear the door opening once again.
