Unfinished Giantess

In your haste to find the shortest path away from her you manage to trip and fall over, the thud you make is enough to alert her to your direction. You panic hoping to hide before she notices you.

"a bush! yes!" [branching path]
"quick, hide behind the ledge you tripped over!" [oral play] [vore optional]
"it's no use... she's faster than you and can hear you run, just give up and accept your fate." [strange insertions] [possibly vore]
"hiding is impossible, but she's massive I can slip into a cave and stay there til she gives up." [escape ending]
"she's actually one of the smaller giantess. I should just be able to outrun her." [impossible stretching] [human onahole] [cumflation]

strange insertions: either a tiny inserting their dick into abnormal locations, (such as the urethra of a dick, or the nipple of a breast.), or a tiny being inserted into a vagina or ass and used like a dildo. the later is often considered vore. the anal insertion will also have the giantess be futa for the sake of prostate play.

oral play: blowjobs, licking, and optionally being placed inside a mouth entirely, or being swallowed (aka vore.), all vore will be safe vore so your character will live to see another day whether you manage to escape or not.

impossible stretching: the magic of the valley reacts with human biology to make them obey porn physics and also be practically indestructible. (see lore). Thus smaller futanari giantess learn that humans can comfortably stretch over their cock and even derive pleasure from it.
human onahole: a human (you) being lifted entirely off the ground, gripped with a hand like an onahole, and utilized as a sex toy rather than any normal sex position.
cumflation: cum being ejaculated into a container that can't contain it and said container expanding to hold all of the cum. in this case your ass or vagina.
