"Now get up" Vines begin to wrap around his arms and legs in order to stop him from moving. Gasping, an even thicker and longer vine wrapped around his hard cock. Its opening bloomed into a rose, engulfed the head of the lucky Robin's dick, and began sucking. Robin whimpered weakly as Ivy rubbed his chest, placing green kisses on his drooling lips.
"I bet that feels good, doesn't it Boy Wonder?"
"Y-y-es! Let me come, Mistress Ivy!" Ivy smirked, summoning more vines to wrap around his hard member. They began to secrete a thick green liquid. Normally, Robin would wonder what that was, but he was too focused on the amazing blowjob he's getting from Ivy's plants. He clenched his fist in reaction to the intense tingling sensation he felt in his penis. He screamed in pleasure as he orgasmed while the rose flower happily pumped his semen. The plants retreated from his cock, allowing the green liquid to seep into his skin. Ivy smiled softly, running a hand along his length, which suddenly began to grow even longer than before. In a matter of seconds, his cock doubled in size -- a twelve inched giant! Ivy licked her lips in anticipation while Robin looked down at his cock in excitement.
"That Miracle Gro did quite a number on you, but now it's my turn to have some fun" Ivy winked, lowering herself to his giant cock. She gave the glans a little squeeze, prompting a groan from Robin as his dick expelled nearly a quart of precum all over her hands. Wiping it all over her hands, she began to lubricate his long dick, pumping it as she did so.
"Do you love being my slave, pretty bird?"
"I love it so much, Mistress Ivy!"
"Good boy..." She pulled out a beaker of pink fluid and began to pour it all over his hard cock. Every drip felt amazing for Robin and sent waves of pleasure throughout his body. Before he knew it, she emptied the entire bottle onto his dick.
"Does that feel good? This chemical will make you hypersensitive, leaving you powerless to my actions. Prepare to be drowning in pleasure, lover" She placed her palm on his head and began to grind it while sexily licking the side of his shaft. With each lick, his dick spurted more and more precum much to Ivy's enjoyment. She summoned plants so that they could happily clean it all up.
"Nngghh YES!!!" He shook violently as his mind was exploding with pleasure from the liquid and Ivy's talented soft hands and tongue. She winked and began to suck his cock while she pumped his dick, moving around the thick pink liquid. He felt everything Ivy did to him tenfold as soon was ready to come.
"Ivy, I'm coming!" She backed off and laughed as he cried in pain.
"Why!?!?" Along with the pheromones, pink liquid, and his now longer cock, he was willing to do anything to come.
"Because you're my slave, Boy Wonder. You don't get what you want. Beg for it, now!" Ivy spat in his mouth and kicked him hard in the balls.
"MISTRESS IVY, PLEASE!"
"Who do you belong to?"
"YOU, MY MISTRESS!"
"Do you love me?"
"I LOVE YOU SO MUCH, IVY!"
"What would you do just to come?"
"ANYTHING, MISTRESS IVY! LET ME SERVE YOU!" Ivy smirked, wrapping her D cups around his cock. She began to rub her supple tits along his tits and began to kiss and lick his head. Robin smiled stupidly, feeling her thick, juicy tongue sliding around his tongue, leaving behind a thick trail of her nectar saliva. Robin's tongue stuck out as his hypersensitivity sent him over the edge.
"Name your poison"
"POISON IVY!!!" Robin cried. Ivy smirked, planting a kiss on his glans as he exploded, bucking his hips as he did so. Ivy smiled, drinking the gallon of jizz coming from his beautiful member.
"We're just getting started, handsome" Ivy winked.
