Tim Drake, the third young man to carry the Robin name, was in his favorite position, pants off, sexy super heroine in his lap and today it was no normal super heroine. He had Miss Martian aka M'gann M'orzz, alias Megan Morse sucking his cock. The sweet, innocent girl from Mars wasn’t like most other girls. With her short red, lime green completion and super cute outfit, she wasn’t as aggressive or slutty as most other heroes. She might wear her white shirt with a large red X tight against her bosom and keep her skirt short, but she was no flirt. She didn’t sleep around, only having sex with a few select people on select occasions. Luckily for Robin he was one of her partners and today was his day to bang the sweet Martian alone in his room in Titan Tower.

“I love human male anatomy! It’s so cute!” Miss Martian giggled as she clutched the base of Robin’s cock and leaned it to give the underside a long, wet lick. Robin shuddered as he felt her smooth tongue work his shaft. Miss Martian was not the best at sucking cock, her technique was sloppy and she didn’t move very fast. However, she was one of the best cock swallowers Robin had ever seen. She could gobble down cock like it was nothing but a wet noodle. Robin watched her lick along the crown of his cock, holding his breath in anticipation for her to wrap her lips around the head and swallow. She shifted her head over his cock, lifting her blue skirted ass in the air and then pushed down.

GULP!

“Fuck yes!” Tight, slick Martian throat covered his cock as his balls pressed against Miss Martian’s chin. From this point on, Miss Martian liked to swallow and hum, making her throat vibrate pleasantly around his cock. It was different then the other girls, but Robin still liked having a throat massage. It left his mind clear enough to think unlike with other girls when all he could focus on was their bobbing heads.

“You know what I love thinking about while I’m getting a blow job from you Megan, the hot bods of other women.” Robin’s statement would normally upset a woman, but Miss Martian just nodded her head slowly nodded her head, wobbling the cock in her tight throat.

“Lately I’ve been thinking about how much fatter some women have gotten. Like Black Canary, I can’t get my mind off her huge fishnet covered bottom jiggling around for everyone to see. I hear that Bruce has been banging her hard since her ass started taking up two seats. Lucky bastard,” Robin grunted as he sunk his fingers into Miss Martian’s red hair and started pumping her head on his cock. Images of Black Canary’s bouncing body making his cock tremble in Miss Martian’s esophagus.

“Then there’s Power Girl. I love seeing her arrive because then I get to see her mega sized rack bounce around, I never thought those melon’s could get any sweeter. But I also love seeing her go, her ass is so big and firm looking. I don’t care if she crushes me, I’m going to try and get under her if she fell from the sky. Being crushed under that ass would be amazing.” Robin grasped her head and directed the rhythm, pushing her face into his pelvis as it suddenly swelled in her throat. His balls bounced off her chin as he went faster, feeling a big orgasm building up inside him. Miss Martian continued massaging his cock with her throat, never doing anything else to aid him in getting off.

“Wonder Woman’s getting chunkier too. I heard her knockers had grown so much that they wouldn’t fit into her breast plate. That and the stars on the bottoms she wear never see sunlight for long because they keep disappearing up her ass crack.” Robin was moving Miss Martian’s head furiously now, saliva running down his thighs as she provided lubricant for him to fuck her throat. “But what bugs me is that now that they are getting fatter, they only want to fuck Superman and Batman, not the Boy Wonder. I want to try sticking my cock in a giant, bouncy ass! I want to feel my body press against blubber! I want to fuck a fat chick!”

Robin ripped Miss Martian off ho cock as the first squirt of cum came out, hitting her on the cheek. Miss Martian smiled as she was bathed in rope after rope of semen as it shot high into the air and fell splattering on her forehead, hair, nose and lips. It dripped all over her face, getting onto her clothes as well. Robin pumped his cock in his fist in front of her face for several seconds, getting as much out and on Miss Martian cute face as possible. She giggled after he was done, enjoying his display of human affection.

“I know how you feel Robin, I have a fantasy too that I want to try, but no one will volunteer to do it with me,” Miss Martian explained as she cleaned up. Robin watched her absorb the cum covering her face into her skin and then watched her do it with her ‘clothes’ too. What she was wearing was just her transformation skills at work. She could change anything about what she wore and what she looked like, which gave Robin an idea.

“Say Megan, how about we both get what we want. You can turn yourself fatter and I can do whatever you need to have your fantasy come to life.”

“Are you sure, I understand that my fantasy is kind of strange for humans?” Miss Martian asked with concern.

“Trust me, after double teaming Wonder girl with Beast Boy while he’s a dog, nothing is too strange for me,” Robin boasted, not even bothering to ask what it was Megan wanted to do. He figured it was something wild for her like anal sex, which Robin had done last night with Ravenger. The martian girl smiled at him, happy to finally live her fantasy.

“Okay, one fat Martian coming up,” Megan said and began to change, turning her cute teenage body into an obese whale.
