She accepted his challenge with a bonus

Tsunade knew that she had no other choice or way to pay off her debts.

“Okay, accept your condition, Raikage!” Tsunade said as she accepted his challenge with no hesitation. “But just double the stakes! I get double the money if I win, but if I lose you will Shizune as a sex **** too. Since she doesn’t know I’m doing this, but I am willing to sacrifice her!”

The Raikage looked at Tsunade with surprise, but then he smirked and nodded his head. “Very well, if you win, I’ll give you twenty million ryo, but if you lose, you both become my sex slaves forever!”

The tension in the room grew thick as Tsunade took a deep breath and stepped closer to the Raikage and knelt in front of him. Her heart pounded in her chest as she opened her top revealing her huge tits and wrapped around his massive cock with her breasts. She had seen her share of large men in her time, but nothing compared to the sheer girth of the Raikage’s member. She could feel the heat radiating off of it, and she knew that this was going to be a challenge.

“The rules are simple, you can only use your breasts so no hands, mouth, or any combo of any kind, also no using any justu! You must make me cum within 5 minutes to win!” The Raikage said as he wanted to make sure that Tsunade wouldn’t use any tricks to win.

Tsunade nodded, her pulse quickening as she took in the challenge. She had never done anything like this before, but desperation made her bold. She leaned in, pressing her substantial breasts around his cock, feeling the veins pulse with anticipation. The Raikage's cock was indeed massive, and she knew it was going to be a tough task, but she had to win. She began to squeeze and massage, her tits moving rhythmically up and down, trying to coax out the cum. Her breasts were large and firm, a result of her Uzumaki genetics, and she hoped they would be enough to get the job done.

Unfortunately, Tsunade doesn’t know or hear that the Raikage’s cock is known as the “Iron Cock” because nobody has not able to make him cum at all in the history of his life as Tsunade had walked into a losing battle as it will be too late when it is over.

Tsunade’s eyes widened slightly as she felt the power of the Raikage’s cock, and she knew she had to give it her all if she wanted to win. She leaned back and pushed her breasts together, creating a tight, warm channel for his length to slide through. She began to move them faster and faster, her heart racing as she felt the weight of the situation pressing down on her. She had never been so focused on a task, and she could feel her breasts starting to ache from the exertion.

Ay watched her intently, his eyes never leaving her chest. He was enjoying the sight of the legendary medical-nin’s breasts in action, but his expression remained stoic, not giving away any signs of pleasure or displeasure. Tsunade’s face was a mask of concentration, her teeth gritted as she worked tirelessly to meet the challenge. The sound of her breasts slapping against each other filled the room, along with the occasional grunt from the Raikage as she tried to find the perfect rhythm to bring him to climax.

As the minutes ticked by, the tension grew unbearable. Tsunade could feel the sweat beading on her forehead and her breasts growing more sensitive from the friction. She tried different techniques, using her entire body to move her tits, squeezing them tightly around his shaft and then releasing, only to repeat the process again. Each movement was calculated, each touch precise, as she tried to find that magical spot that would make him cum.

The Raikage's breathing never grew heavier as his face remained stoic. Tsunade sees no sign of pleasure as he has his arms behind his head relaxing if she is not affecting him at all. Her own chest heaved with the effort, her tits bouncing and jiggling with each stroke. The room was hot, the only sound the slapping of skin on skin and the occasional moan from Tsunade as she pushed herself to the limit.

With only two minutes left, Tsunade knew she had to change tactics. She leaned forward, her large breasts pressing against his cock as she looked at him, "I know you enjoy this, Raikage. Let me make you feel good." Her voice was low and seductive, a stark contrast to the sternness she had shown moments ago.

The Raikage's eyes narrowed slightly, but he didn’t say a word, continuing to watch her every move. Tsunade took a moment to appreciate the size and power of his cock before her, then leaned back, using her arms to hold her breasts together, she began to bounce them up and down with increasing speed and ****. Her nipples had turned a dark shade of pink, and she could feel the heat from his cock burning her skin. She knew she had to push herself harder.

With one minute to go, she tried a new approach. She took a deep breath and began to chant a jutsu under her breath, her chakra focusing on her breasts. The Raikage's eyes widened in surprise as he felt an unusual warmth enveloping his cock. Her breasts grew slightly larger and firmer, and she began to squeeze them around his length with more power than before. The sensation was intense, and she could feel the muscles in her chest straining with the effort.

Tsunade knows that she is cheating, but she tries to make him cum fast enough before he notices her using chakra. She squeezes her breasts tighter, her chakra-infused tits moving in a way that seemed almost superhuman. The Raikage's cock grew even harder, and she could feel the pulsing building within his cock, but he remained silent, watching her with a keen eye.

With seconds left on the clock, Tsunade feels the pulsing of the Raikage’s cock growing stronger, and she knows she's close. She bites her bottom lip and pushes her breasts together as hard as she can, the warmth from her chakra mixing with the heat of his cock. Suddenly, the Raikage's eyes widen, and he lets out a guttural groan, his body tensing up as he explodes with a massive load of cum that spurts out, covering Tsunade's chest and face.

The former Hokage sighs in relief and triumph, her cheeks flushed from the exertion. She had done it.
