Robin had waited At the extraction point for far too long. He realized something was wrong so He tried to contact Batman.

"Batman Whats you're location?"

As Ivy was finishing reprogramming Batman Robin's voice came through.

Ivy smirked and told Batman " Get him here so I can show him my love." 

Batman replied to Robin " I am in the Bowery district across the court house."

Robin arrived a few moments later only to find no one there. As he was about to spear He saw something out of the corner of his eye.

"Hello My Pretty bird." Ivy seductively cooed.

"What did you yo with Batman?" Robin demanded.

 "I didn't do anything He didn't want Robin." Ivy replied. With that she blew a Cloud of Pheromone dust into Robins face. As he coughed he saw Ivy lifting her Huge tits through her leaf corset.

"Like what you see Robbie?" Ivy Aked.

"I-I-Ivy you're coming with me back to arkham where you belong." Robin stammered while looking at her marvelous chest. Trying to ignore the growing bulge in his costume. 

" I know you'll be cumming but why not look at my big titties Robin, after all what teenage boy doesn't like a pair of tits, after all mine are hypnotic aren't they?" Ivy replied.

Ivy lowered the corset so her tits would be free and jiggly. As she shook her tits Robin tried to look away only to be met with another pheromone cloud. " Look at my tits Robin they are so big, So round, so sexy, so hypnotic." Ivy seductively said. Robin moaned as he stared at her big tits. Ivy smirked as she told him "lower you're pants and start stroking." As Robin complies he couldn't help but let out a moan. so Ivy got closer to him. With her Tits right in his face filling his vision, his mind melted and he could only think of how sexy her nipples were how they were drawing him in. How her cleavage was drawing him in, how he wanted to be hers forever. Ivy then lowered herself and put his dick in between her tits. She brought her tits up and down in and down. Robin whimpered as he bucked his hips faster in her cleavage. "Yesss robin become mine, Wouldn't you like to put you're face right here in between my tits and be smothered to death? Ivy hissed. Robin let out a groan as he came everywhere. "You're now my slave until yo're death robin." Ivy said while kissing him on the lips. Sealing him to her. Forever
