Tentacle Sex... Incest?

[sirhugs]

Brother (20ish) is a bit odd, so when he asks Mom and dad if he can screen off a corner of the basement to put in an aquarium they think "how cute, he's growing fishies"

Sister (18) is in basement one morning in just her bra and panties, looking for clean clothes in the laundry, when she hears sex noises coming out from behind the blankets that partition off Brother's space.

She peeps through a gap in the curtains, and sees that instead of fish, Brother has grown a tentacle monster- and one of the tentacles is jacking Brother off!

Forgetting that she is not quite dressed, Sister enters to confront Brother.... who observes how hard her nipples are and suggests to her that tentacles can do wonders for women as well...

I like it though maybe it should be a bit more than just a tentacle job. Maybe bro is also getting straight up sodomized by the tentacles (consensually) while fucking it's curled tentacles when sis walks in. She laughs at brother who is too embarrassed to really argue back when the tentacles yank his sister's shorts down and show off how wet she is. Brother gets his turn to heckle and sis becomes bothered and hot by the tentacles, eventually stripping off and belly flopping into the mess to get fucked. Brother keeps fucking away, cumming over and over as he gets fucked and watches his sister get pleasured.

Then sis starts whining that the tentacles in her got soft, so in the heat of the moment she began to to help. So in a nasty threeway they have hot sex and sis cums hard, while bro gets tanked off at the last second and the TM slurps his cum and then comes inside of sis.

...turns out tentacle monsters, when deprived of a natural mate, will take sperm from a male of another species and alter it to impregnate a female of that species. So now sis is pregnant with tiny tentacles that are technically her brother's babies as well. So now they have to keep things a secret, have sis give birth in secret, and hope they can drain the monster before their mother finds it.

I'm on the road and didn't get to it till Sunday. Anyway, I've been transitioning from tentacles to mantids. Maybe bro is raising hypersexual giant mantids... with their decapitate-males urge suppressed, right?

Why can't mom get into the action too? And some aunts and cousins? Yes, Sonny provides DNA to the tentacle-human hybrids... who will all have his face. Where will the wee critters live? Who will raise them? Do they have special dietary requirements? Will they be baptized? Must they attend charter schools? Can they dance?
