Both, both is good

Tamara looks lustfully at Hannahs body pressenting a full view of her gaping pussy. She kneels dow between Hannahs legs and positions her dick against hannahs slit.

"Ah, fuck" moans Tamara as even though Hannahs pussy is stretched open, Tamara's girth is too much and rubs against her inner walls. Tamara is also getting more clear sensations from Hannahs body with the increased amount of her slime integrating with her. In a lapse of concentration Tamara undoes the command holding Hannahs vagina open causing it to tighten around Tamaras dick and the stimulation causes them to cum in unison.

"Aaah!" Tamara and Hannah moan as they climax, Hannah being filled even further. Tamara has her slime redistribute in Hannahs body. She convulses in pleasure as her breasts expand and her ass enlargens.

"Wow, you sure turned out great." Tamara says admiring the enhancements she made to Hannah. Tamara lifts Hannah up off the floor with her dick still inside her. The sudden change in position causes Hannah to snap out of her trance like state and take in the situtation.

"Sarah! Whats going on...ah!" Hannahs questioning is cut off by a moan as Tamara sits down on a bathroom counter letting Hannah slide further down on her dick.

"Well, I'd say we have been fucking like animals for quite a while now, well more like animal and slime monster to be more accurate." Tamara states.

"Wait...we should stop...this isn't right...ahh my ass" protests Hannah as Tamara stealthily created a slime tentacle which is now probing Hannahs tight ass. Tamara begins thrusting into both of Hannahs holes, causing her to become a moaning mess.

"Ah....wait...we...ah!...need to...stop..." Hannah manages to blurt out inbetween moans.

Tamara in order to tease Hannahs immediately stops moving.

"Huh, what why did you stop..." Hannah says disappointingly.

"Well you told me stop, so I did." Tamara retorts.

"Well I did but..." Hannah says sheepishly.

"But...?" Tamara says looking at Hannah squirming on her dicks.

"Okay I didn't want you to stop...Janes gonna be so mad at me...but I haven't felt anything like this before please do more." Hannah pleads.

"Fine but I think you need some punishment for not being truthful." Tamara replies with a smirk. Tamara commits a large amount of slime to her tentacle and forces further into Hannahs ass.

"Aah... its soo deep...don't...stop..." Hannah moans.

"Wasn't planning to." Tamara states, forcing her tentacle further into Hannahs body. "I wonder how you look from this side."

Hannah can only moan in pleasure as the tentacle enters her stomach, Tamara's slime having already altered Hannahs body to the point where this strange insertion only brings pleasure. Hannah lets out one more moan before a with a gurgle the tentacle bursts out of her mouth having completed its journey.

"Hah" Tamara laughs at the Hannahs wide eyed expression in the mirror with her tentacle sticking out of Hannahs mouth.

"Might as well go all the way now that we have come this far." Tamara states as she controls her tentacle to invade Hannahs brain through her nose and ears. Hannah lets out some muffled moans as Tamara gains full control over Hannah and access to he mind.
