Caught by my StepFamily But I Can't Stop Cumming!

Did you have a lot of stepfamily stay with you over the Holidays? I sure did! I had the house full of stepfamily, several to a room. And wouldn't you know it, this is when I get so undeniably, overwhelmingly, urgently horny! I can't take it! I need to do something about this, but I can't make any noise.
From my bedside drawer, I take out my big, chocolatey brown dildo vibrator. It runs pretty quietly, I think. For reassurance, I take a look down the hall - all is dark and quiet. I'm sure everyone has gone to rest.
I start pleasuring myself by rubbing the dildo against my pussy, not turning the vibrator on yet. I get on the bed, spreading my legs wide, pumping my hips in the air, as I grind against this hot, velvety dildo.
I was quite sure I was staying quiet. I know I couldn't help but gasp when that thick dildo entered my tight pussy. And maybe I moaned a little when I turned on the vibe. But, certainly not loud enough to wake anyone up, I'm quite sure. I guess I always lose my head a bit when giving in to pleasure, and especially when I'm approaching orgasm.
As the waves of orgasm start to roll through me, I lift my head and my bedroom door is wide open! First one stepfamily member is in the doorway... then another... and another... until it seems like everyone is just standing there staring at me, legs spread wide, dildo plunged into my pussy, as I convulse in an orgasm that won't stop! In my immense shame, my pussy has clamped down on the vibrator, and I can't get it out!! My fingers are too slippery with my pussy juices to get a good grip on it! I can't barely even say any intelligible words through wailing in my pleasure and shame.
When I am finally able to get the vibrator out, my hips have seized up, and I can't close my legs! So all that serves to do is show them my gaping, wet hole! At least, my orgasm finally comes to an end and I'm able to shout at them to "GET OUT!"
Now I am alone in my utter shame and humiliation. I can't get the image of my stepfamily all standing there, watching me, spread wide open, body racked by intense endless orgasm... and I can't help the feeling that's coming over me...
