All of them!

With a shudder of distaste, Grex manoeuvred himself above Gina. He extended three of his manipulators to fill all three of her primary openings at once.

Gina managed a muffled squeal of protest as thick rubbery tentacles **** themselves into her mouth, pussy, and asshole. Fortunately, the alien’s coating of slime provided generous lubrication preventing the unwanted penetration from being too painful. She tried to bite down on the one in her mouth but its skin proved too tough for her to do any damage.

“Oh wow you were right it is warm, soft too. Grex said squirming and probing deep inside Gina “I thought it would be all hard and flaky but this is pretty nice.”

Tears stung Gina's eyes as Grex stroked her bare skin. She wanted to scream at the alien to stop but even if she wasn't gagged she doubted they'd listen. It was clear that the pair doesn't think of her as a person. They saw her as a curiosity, a scientific oddity to be explored as they saw fit.

Still, despite her fear and humiliation, it was also becoming clear that they didn't intend her any harm. In a lot of ways, they seemed as confused and frightened as she was. If she could stay calm and find a way to really talk to them she hoped to convince them to let her go. She **** herself to slow her breathing and relax her muscles. She moaned around the gag in her mouth as the discomfort in her stretched holes eased. At the same time, N’vox also relaxed her grip enough to let Gina wiggle her fingers and toes. She flexed her extremities restoring her circulation and making the gel-like alien giggle.

“Hehe. That tickles” N’vox tittered “Oooh it’s been a while since anyone touched me like that. Not since Rigel VII in fact...”

“Great Zarquon.” Grex objected from above the small of Gina’s back. “This whole mess is awkward enough without you bringing your love life into it.”

“Mmph!” agreed Gina

As much as she sympathised with her captor (she’d been going through a bit of a dry spell herself.) she did not want to hear the gory details of this thing’s holiday romance. Unless… perhaps there was an opportunity here. If she could just distract the thing…?
