She upgrades his cum production

Samus let's go of his balls with her free hand and reaches back to the terminal. She selects an upgrade to increase ball size and that multiplies cum production exponentially. While still sucking him off with her mouth onahole she grabs the chip and inserts it into the back of his neck. Zevan's testicles feel warm and heavier as they increase to the size of softballs and begin working overtime.

Zevan feels his orgasm build. "Samus, I'm going to cum soon." He moans out.

"Shoot it all out, give me every drop of alien baby batter you've got!" Samus yells in excitement. Zevan groans as he finally cums, his cock shooting out his jizz into the onahole. Samus feels the warm cum filling the toy and quickly selects an option. Inside her mask a phallus is made and thrust into her eager mouth as his cum is redirected through her suit and into her mouth. Samus feels the his semen fill her mouth and coat her tongue as she tastes the foreign cum, still salty but a noticeably different brininess. Despite this Samus relishes the taste in the alien's distinct cum. As her mouth begins to fill she has **** but to start swallowing.

Zevan continues to pump his enlarged balls as he continues to cum. He gazes into Samus' visor and sees her cheeks puff out as she hurriedly drinks his seed. Samus swallows as fast as she can as her once empty stomach begins to not only fill but swell a bit from the voluminous snack. The suit detects that it is too much for her to drink as it instead begins spraying it out the sides of the phallus as it gives Samus a facial as she drinks. The thick musky scent filling her nostrils as the cum covers her.

Zevan can't believe it's his cum covering the legendary bounty hunter's face as he feels a swell of masculine pride. And that pride is immediately replaced by worry as he sees her helmet begin to fill up with his cum. Through the visor he can see the cum pool and rise up as it engulfs her.

Although Samus is no longer able to breathe due to the cum surrounding her head and flooding her mouth, nostrils and even her ear canals, she is in pure bliss as she still drinks down more of the alien's cum as she wants to drink as much as she can.

Finally the Zebesian's orgasm subsides as he pulls out of the onahole arm. At this point he can no longer see Samus' face at all as he can only see his cum tinted green through the visor. Samus falls to her knees as the lack of oxygen is taking it's effect. Acting fast Zevan grabs her helmet with his pincers and pulls. After a few tugs he is finally able to pull the helmet off as a torrent of cum spills out of it. Samus falls on her side, her head completely covered in a thick layer of semen that sticks to her. Samus begins coughing up the Zebesian's fluids as it pours out of her mouth. Finally she is able to gasp for air and breathe as Zevan rushes over.

"Are you okay?" He asks worried.

"That-cough- that was the single most pleasurable thing I've ever done. I feel so warm, my stomach so full..." Samus says with a woozy expression. Zevan can only chuckle, happy that she is okay and enjoyed it so much. As they rest a bit they wonder what to do next.
