"I wish that Ava would be super horny all the time, and needs to constantly masturbate to relieve the pressure," I said, "And again, no one but us will think this is unusual, and everyone will be okay with Ava masturbating in public."
As soon as I finished saying those words, Ava flinched. A flush rose in her face, while the tits on her engorged breasts hardened and her pussy immediately started glistening with juices. A moan escaped her gaping mouth as her hands clasped at her pussy and her knees buckled.
"What... the... fuck?..." she muttered between gasping breaths.
"Now what's wrong?" I asked, feigning annoyance.
"I don't... I don't know..." she moaned, "So hot..."
"Oh, is that all? If you need to cum, just go ahead."
"Wh-what?"
"Come on, Ava, it's not like it's a big secret," I said, rolling my eyes and hiding my grin, "Everyone knows you have that weird medical condition where you have to cum like 20 times a day. I even remember you explaining it to me the first day we met, about how that's why you don't bother wearing clothes, since they just get in the way."
Ava stared in shock, mouth agape and chest heaving in interesting ways as her hands seemed to instinctively start playing with her wet folds.
"Is that why you've been acting so weird today? You're backed up and can't think straight?" I asked, "Ava, you don't have to be so self-conscious. I doubt there's really anyone in town who hasn't seen you work one off at least once. If you need to cum, just cum."
Any retort Ava had to my normally ludicrous comments were lost in a particularly loud moan as she sank to her knees and started actively playing with herself, while I merely smirked at the display.
