Selena eyed Bruce's spreadeagled form greedily for a moment, running a hand along the dimpled curvature of her fat thigh. "I think -", she turned, rolling over until she was laying chest-down on top of Bruce's body, "I'm going to have some fun with you for now... How long do you think you can hold your breath, Bat-boy?" Bruce resumed his wriggling beneath Selena's massive, naked body, but it was no use. The whale-sized vixen leaned forward, and before Bruce could so much as whimper his entire head was buried beneath the burgeoning mass of Selena's oversized breasts.
Selena grinned as she used her elbows to smoosh her breasts down fully over Bruce's face, ensuring an airtight seal. The once-hero of Gotham tugged and jerked frantically beneath her swollen body, but he couldn't have made her budge if he wanted to. As the minutes ticked by, Selena felt Bruce's violent spasms dwindle to mere twitches. Only when it seemed likely that Bruce was at the edge of unconsciousness did she lift herself slightly.
Immediately, Bruce craned his neck back, desperately sucking air into his lungs through his nose. He was bright red in the face and looked dizzy. Selena clucked her tongue playfully, "Tut-tut, Mr. Batman - you're losing your edge." She shifted her massive weight back slightly, causing the bed to groan beneath the pair of them. "You couldn't have been under me for, what, five minutes? And look at you - you almost passed out. Some 'hero' you are..."
With a deviant smirk still teasing at the edge of her lips, Selena moved off of Bruce, crawling up toward his head. "Tell you what, Bruce. I'll make you a square deal - give you a fair chance, 'cause I'm just that kind of swell girl." She moved to her side, swinging a heavy, jiggling leg out over Bruce's head until she was straddling him, her gargantuan, bare-skinned butt planted firmly on his chest. Turning her head to look back at him, Selena winked and continued, "I'm going to spread these heavenly cheeks of mine, lean back, and bury your face where the sun doesn't shine..." She giggled as Bruce squirmed nervously beneath her again. "But before I do that, I'm going to pull that tape off of your mouth. Here's the deal, if you can slip that silver tongue of yours deep enough into my ass to get me off, I'll let you live. But, if you bore me back there, I won't get off of you until I'm sure you've stopped breathing. Deal, Bat-boy?"
Selena reached a bloated arm back and grasped the tape covering Bruce's mouth, tugging it sharply off of his head. Bruce had barely enough to spit the behemoth woman's panties out of his mouth before she descended over him, engulfing his head in the darkness of her enormous ass cheeks. The scent was an overwhelmingly earthy and moist, a mixture of sweat and juices from Selena's crotch. In the back of Bruce's mind, he thanked the universe that his captor was at least aroused already. From beneath the muffling confines of Selena's rump, he heard her teasing voice, "Tick-tock, Bruce - best not to keep me waiting
..."
