Black Cat stared wide eyed at her hostage. Her action had gotten her completely off guard. One minute she was grinding Mary Jane's face between her butt cheeks, then the next thing she knew, a tongue passed over them.
On the opposite side, Mary Jane was more surprised, and terrified over what just happened. She was so lost in lust that she went for the ass of the very woman who kidnapped her, and was trying to steal Peter away. All that jiggling fat before made her so horny, and to make matters worse, now the thought of being in handcuffed in the prescence of this fat seductress was turning her on too.
Even so, she shuddered when she saw Black Cat smile.

"My, my, my, Mary Jane, you naughty girl." Mary Jane shook her head as Cat looked down at her, trying to shake her feelings. "Does my blubber butt turn you on?" Cat asked with a smirk.
"N-No." MJ whimpered.
"Really?" Black Cat turned back around, shoving her ass back in MJ's face. "Don't you just want to caress my fat, beautiful ass?" Cat asked. Mary Jane continued to whimper as she returned to where this started. With Cat lifted above her lap, she had her cheeks nearly wrapping around her face.
Mary Jane couldn't stand it much longer. When Felicia was skinny, she was a bomb-shell that any man, or woman, would be happy to screw, but this..................

"Ow!" this time Felicia felt Mary Jane's pearly whites dig in her cheeks. She didn't stay mad about the pain though, as it proved her point.
"Okay! Yes, yes I'm turned on by your ass, yes I love your new body, and yes I want to fuck every fat inch of it. I don't care what you do to me, just fuck me, please." Mary Jane didn't deny her feelings anymore. She had to have Felicia.
Mary Jane saw an evil smile cross Felicia's face.

"I can't say that I hadn't thought about this. It's been so long since I've gotten any, and your body is so hot." Felicia kneeled down in front of Mary Jane. She reached out to touch her, finding her hostage trembling at her very touch.
Felicia then finally activated her Black Cat powers. Once her hair became silver, she ripped off Mary Jane's top with her claws, snapping the bra strap with her nails.

"Felicia!" Mary Jane moaned as she felt her hot tongue caressing her body. She could feel the Cat licking her neck, sending shivers up her spine. Slowly her tongue switched to licking circles around her bulging tummy. Felicia actually enjoyed hearing the gurgles and growns from the stuffed gut, it was starting to turn her on. Mary Jane for a moment wished there was more for her to lick.
She teased the pushed out belly button, and stroked her hands and kissed over that fleshy dome, recieving even more moans from her captive.

"Nice titties." Cat handled them with care, caressing each mound in her plump hands. They were so big and lucious, though it made Felicia smirk at how much bigger hers were now.
Unable to resist herself, Felicia planted her mouth on the left nipple. Mary Jane let out sharp moans as this hot, fat blond nursed from her tit.
Felicia mmmmmed around the now erect, pink stub. Mary Jane's body had tasted so delicious. All Felicia wanted to do was shove this fat redhead down her gullet.
She resisted though, Mary Jane was still not fat enough, and they were both way too horny to depart from each other. After biting her neck for another taste, Felicia tore off
MJ's shorts and underwear.

"Yes! Lick my pussy, Faster!" Mary Jane begged. In the midst of ignoring her hunger, Black Cat moved to a spot that delivered an even more delicious treat. Her pussy walls rippled around Cat's tongue. She felt Cat rub her face against her inner thighs, and especially her belly. All this mixed into a perfect storm of pleasure.

Black Cat by now was losing her mind. The very scent of of Mary Jane's cum was so delicious, though not as delicious as the taste. Black Cat lapped and sucked every drop she could get, enjoying the sweetes drink she had every had.
Unfortunately, she couldn't savor this moment. She knew that if she didn't do something fast, Mary Jane was going to get deep throated by her. So Cat licked and sucked on the clitoris as it begged for her attention. She nibbled the inner flesh, resisting the urge to ravenously attack it.

Finally Mary Jane through her head and erupted all over the Black Cat. Her captor downed all the cum, again nothing escaped her hungry. For a twat that hadn't seen some action in almost a month, Mary Jane had a lot to give up.

"Pussy, for the pussy cat." Felicia chuckled at that. She licked her paws and anywhere else on her for the few drops that leaked out beneath her reach, purring at the delicous, tangy flavor.
This was no time to savor the taste either though, as her hunger had only grown stronger. Her belly was hungry, but it was also filled with hot girl cum.

So Black Cat had to two options here.
She could either, forget about her plans and eat Mary Jane "Fatson".
Or she could fuck her brains out, since MJ still looked like she wanted some more.
