They went to Sekibanki's home near the Human Village. She stripped and lay down, cradling her "main" head in her arms. Kars began rubbing his meat against her hole. Meanwhile, the head resting on her belly licked the glans of his rod.
Kars stuffed his cock into the mouth of the head on her belly for a while before Sekibanki #2 insisted it was her turn to be attached to the body so she could feel the pleasure.
"Alright, I'm going in."
Sekibanki watched as the rod slowly entered her hole. The thick shaft forced her tight walls open, sending a jolt of pleasure through her. She used her tongue to lick her own clitoris, further heightening the sensation.
"How is it? My meat feels good, right?"
"Hmph~ it's alright... if you want to actually satisfy me, it'll take more than... ahhh! Don't just start moving like that!"
Sekibanki tried to maintain her cool, but as Kars began to thrust, she immediately crumbled. Her face softened into a look of pure, shy bliss.
She could feel every inch of the powerful rod inside her. Meanwhile, the head on her belly could feel the meat slamming into the deepest part of her internal space. She could hear the wet, churning sounds and the dull thud of the rod hitting her womb.
Kars seemed to be doing it on purpose—every thrust made her lower belly bulge outward, right under the head she was holding. It felt as if his cock was trying to punch through her body and enter her brain.
The lewd sounds and the constant pressure against her "head" made Sekibanki's mind go fuzzy.
Sekibanki #2 flew over, kissed the "main" head, and the two identical faces began to make out. Kars found the sight of her kissing herself while being fucked incredibly erotic. Both heads then moved to her breasts, each taking a nipple and sucking hard.
Sekibanki let out muffled groans and moans. This was a level of self-indulgence she had never imagined.
"Ahhh~ I'm gonna go! My hole is gonna climax!"
Finally, Sekibanki couldn't take it anymore. She watched Kars speed up his thrusting, her body shaking with every impact. When she hit her peak, a fountain of love-juice sprayed onto his meat. Kars followed suit, pumping his cum into her pulsing womb. She took it all, her internal space filling to the brim.
As the meat throbbed inside her, she continued to shiver.
"Alright, alright! My turn! My turn!"
Sekibanki #2 impatiently snapped onto her neck. The moment she connected, the residual pleasure from the climax hit her like a wave, sending her into an immediate second orgasm.
"Ahhh! This is too good! How can a cock feel this good! I love this! Kars, your meat is perfect for me! Quick... keep moving! I want more!"
Kars obliged. He continued to pump inside her cum-filled hole. The semen sloshed around inside her, making Sekibanki #2's moans even more frantic.
"Ahhh~ yes... just like that! Harder... use that rod to wreck my body! I'm so happy... this feels incredible~"
She pulled another head over and started kissing it.
Soon, more heads appeared. All nine heads were now in the room. It was a crowded and chaotic scene. Some heads bit her breasts, some kissed Kars, others licked his body or his bouncing balls.
Kars would swap the heads on her neck frequently, experiencing every different personality during the act. Each one reacted differently to the fucking, which only increased Kars's enjoyment. He didn't want to pull out.
"Ahhh~ I'm gonna go again... that's the tenth time already~"
Sekibanki was now holding two heads to her breasts. Her belly was bloated like she was pregnant, making her look like a mother nursing two children.
She looked at the tireless Kars and felt like she was going to be broken by his meat. She quickly swapped heads again to let another one take the brunt of it.
"Ahhh~!"
With another climax, her belly swelled further. In her dazed, satisfied state, her head popped off her neck, and the next one immediately took its place.
