Miss Martian’s body might have been huge, but her womb wasn’t nearly as enormous. Robin had to curl up and hug his knees to keep from being crushed in the pulsating prison. Like the last time he was in Miss Martian, he could hear her moans and gasps around him. The womb trembled as small orgasms shot through her flabby body, shaking Robin around. He breathed in the thick air deeply, trying to figure out a way out of Megan that would also give him a chance to escape her lustful grasp. He had gotten more pussy and ass then he ever wanted and was now in need of a nice hot shower to clean up the various slims he had collected on his journey through Megan.

Robin wondered what Batman would do, but realized his mentor would have never ended up in a spot like this.

As he tried to come up with a plan, the muscles loosened around him and he felt himself being pushed back out headfirst. The top of his head breached the cervix, rubbing his face against the wet, fleshy inside of Miss Martian’s cunt. Grunts echoed around him as his head popped out of Miss Martian’s twat in a spray of feminine juices.

Megan’s thick puffy labia wrapped around his neck like a collar, throbbing softly with every twitch Megan made. He coughed harshly as he breathed in the cool air as fast as his burning lungs would allow. He stared at the huge green underside of Miss Martian’s belly until he saw two chubby hands reaching for him. Miss Martian grabbed Robin by the head and with a single pull he came out with a wet slurping sound. Megan moaned loudly, even more juices squirting out as Robin was removed. She tossed Robin on her huge belly as another orgasm raced through her whale of a body.

Soaked to the bone and sore all over, Robin just lay there on his stomach as they belly rippled and undulated underneath him. He did react when he felt himself start sinking in to the enormous belly. “What the…” Robin groaned and tried to get up, but found his body stuck to the green alien flesh. It started oozing over him, the flesh like clay that he was pushing down with his body. Only this clay wasn’t letting him go and it was slowly covering his body. His chest, legs and arms were inside Megan’s yielding flesh and he noted that his cock was in their too. He sunk faster, Megan groaning with every inch that was pulled into her. Robin lifted his head and stared at Megan’s giant breasts, trying to look her in the eye over the huge mounds.

“Megan…. Please…” He gasped out as the flesh consumed most of his body. He could feel his body wrapped in Megan’s belly flesh. It was like warm, smooth mud was covering his body. He didn’t want to be pulled in any further, but he didn’t have a choice. Megan reached past her breast and pushed down on Robin’s head, sending it sinking into her flesh. Robin disappeared inside the malleable green belly and Megan lay there silently with her eyes closed until a loud moan sounded from her and she bucked hard on the bed. Her stomach rippled as her meal moved, giving her the pleasure she wanted so bad.

Robin was inside Megan’s belly, but not inside her stomach. The Martian girl had removed her stomach and all other organs leaving only a blob of green goo in its place. Robin tried to swim through the clay like flesh, but it was too thick for him to do more then lightly thrash. Hot, thick flesh covered him all over like a blanket. It moved him around, pushing him from one end of Megan’s huge round stomach to the other. Bulges moved at the bottom of her gut and then pressed out her flesh just under her breasts. The only thing that remained constant was nothing came out. If the inside of her stomach was like clay then the top was like rubber, it could be pushed out, but not broken.

As Robin was pushed through her malleable belly, Miss Martian was lost in the intense pleasure she got. Human sex was good, but what she was doing was better. This was Martian sex and it made every cell in her shape shifting body sing. But it could only last for so long. Megan knew humans had this strange need to breath and Robin was almost out of air. She relaxed the cell structure on her belly and reached into her gooey flesh. Pulled out by his armpits, Robin gasped for air once again. Heedless to any discomfort Robin could be in, Miss Martian’s next orifice trebled in hunger to eat the Boy Wonder.
