I'm still thinking about those inflatable knots, though. Just sliding the toy inside a pretty thing, hearing that wet sound as it goes, watching their face as they take it to the hilt. Then, giving them the first pump that just makes it slightly bigger, watching the way their eyes widen as they feel the stretch for the first time. It's still small, so I can fuck it out of them before thrusting it inside, making them grow more wet as they feel the round shape go in and out of their pussy. Once they're somewhat used to it, I inflate it twice all at once, smirking at them as I see the surprise on their face. At this point, it's slightly bigger than what they're used to taking, so it clings to their walls as I move my hips, forcing it out of their hole before fucking it back inside. Once they start to moan louder, almost reaching their peak, I inflate it again and again and again. This time, I stop every movement and stare down at their pussy as I slowly pull my hips back. It stretches their hole, stuck inside by its sheer size and refusing to leave that warmth. They're whining, desperate as they lose that edge and try to get used to this growing thing taking up so much space, bigger than anything their tight pussy ever took. I just smile, asking if it feels good feeling my knot stretching their pretty hole like this, calling them a slut for even taking something this big inside them. Finally, as they try to fuck themselves on this huge knot, I bring a vibrator to their clit, making them come again and again and again while stuffed full, clenching around it as they shake and tremble.
