Sooo, 7 years ago, I"m living with my at the time gf and her sister. Things hadn't been great and she went on like a recharge back home on her parents property and left me at the apartment. And I said fuck it. I bought some drugs, some booze, and had the place to myself, so porn, all the porn I haven't been watching. So the hours pass and I'm just edging my way to the best nut in forever, in apartment alone. My cock is raw and like crying precum. I have the headphones, porn full blast, to this day, I don't know why, I was paranoid the neighbours would here or something stupid. I don't hear the key in the door, and I don't hear it unlock, and I don't hear the sister drunkenly stumble in. Im going full speed until I see her reflection in the screen of the computer and I almost jump, but I try and hide my massive erection, and stop the porn that is now screaming through the headphones.

"Fuck I thought you were out of town" She just stands there like a drunken swaying zombie, staring at me, and this smile creeps across her face. She lunges at me, and pushes my hands away, dropping to her knees. Im stunned, cause without a word, she just downs the entirety of my cock, and I nearly cum when i feel the back of her throat. I go to say something in protest, but her mouth is so fucking wet and it feels so unbelievably good on my swollen steel hard cock. I have never been harder. So instead of trying to stop her, i grab her hair, and just immediately give up. She is sucking my cock like my cum is her only source of nourishment. I am not even watching porn, im so fucking overwhelmed. She is fucking unbelievably good at sucking cock, but specifically it truly felt in that moment, that her mouth and my cock were destined to meet. She is ravenous but she is going with what my cock is doing and then I realize oh fuck i'm going to come, and it is coming and oh fuck, i'm about to blow.

"Stop, stop, stop I can't Im going...im coming....im coming..." I whimper, almost drooling, as I try and pull her off. And she wraps her arms around my waist me as I try, holding on.

She mumbles with a mouthful of my cock, that she is forcing to the back of her throat...shes moaning mmmhm, yes, cum in my....mmmhm. So excited for my load.

She doesn't have to wait too long as I fucking burst and she squeals with the first shot.

I start moaning uncontrollably, I grab a fistful of her hair and just start unloading into her mouth and I can feel her lapping it up. I fire countless, hot, thick loads into her mouth, and she doesn't stop swallowing. She opens her mouth and retreats and my last several over her lips and chin, before vampirically swallowing my dick again.

She empties me before letting my cock go, and I fall back. She smiles, eats the cum off her hand from her face, and she stands up. She says nothing and goes to her room.

And in post nut clarity I was floored, a little guilty, but what the fuck just happened.

We never talked about it, it never happened again, but I tried to replicate that scenario so many times. And she would watch me wank for too long but just leave. But she would leave her door open. And I know she wanted me to make a move. But I ended up moving out and we never spoke about it and my ex definitely doesn't know.

Fuck I have never stopped thinking about that night.
