6/8
First of all, Tangene had to drag herself, huffing and puffing as she went. "I've eaten a lot of tasty, juicy reindeer-moss..." she said to herself under her sighs. She, too, had a bloated stomach that was roughly the size of Iho's, but it was much harder and heavier since she had only eaten hard food. She looked much more like an overstuffed hippopotamus than a normal reindeer. As she dragged right towards the dead center of Iho's belly, she made a great effort to lift her whole body up and back just by bouncing her belly; since her legs were well off the ground, she held on to her own fat for support. At the time her posterior was already on the ground, Tangene prepared to puff out her stuffed belly and right into Iho's. Her stretching belly caused Iho's rolls to crease up in contact until the upper belly started to cover his face, causing loud bubbling and sloshing. However, Iho was comforted so much when he felt his mother's body. By the time Tangene felt her son's undigested bananas beginning to poke her belly, she started to rock slowly back and forth. With occasional contented sighs, she was rocking her hard belly so that the bananas inside Iho were about slowly getting crushed. But after a while, the pain had set in from all this stretching and straining. "I need to drink!" said Tangene under her sighs.

UPDATE (12/10) = I have had a lot of trouble uploading my revision, because I spotted some grammatical errors concerning gender late in time. Tangene is supposed to say:
«Я съела много вкусного, сочного ягеля. Мне нужна выпить!»
