Before Nawaki could respond, Tsunade leaned in for a kiss.
Nawaki didn't resist her at all, he kissed her back so hard that she made a cute sound in her throat. That noise was followed by a low growl of desire as Nawaki opened her mouth, and she thrust her tongue into his mouth.
That grunt made a shiver run through Nawaki's body, making him wrap his arms around her, reaching her bulging ass and very firm and soft, pulling her closer to him, gluing their bodies together.
Tsunade seemed to moan at the feel of her hard nipples pressing into his chest. Nawaki gasped in the kiss as she moved back and forth across his lap, sliding her breasts onto his chest.
"Ahh..." This caused Tsunade to emit a soft moan as her aching nipples were teased against his muscular chest.
Nawaki's T-shirt was fine knit, not unlike him without a T-shirt, and her nightdress was even thinner, giving her the feeling of naked contact.
They started kissing harder as their tongues waged war like young lovers.
Tsunade moans again softly as Nawaki withdraws his lips from hers, lowering his head and trapping his lips on the soft skin of her neck.
"Mm, yes Nawaki!" Tsunade growls, letting her head fall back, giving Nawaki the best access to her neck.
As Tsunade rested her chin on his shoulder, Nawaki kissed her neck more slowly and sensually.
Tsunade ran her nails along Nawaki's broad back, loving the soft sigh of pleasure he let out on her skin. Grabbing the back of his head, she threaded her fingers through his still damp hair and gently pulled his lips from her neck.
As Nawaki looks at her with his blurry eyes, she gives a seductive smile and this time pushing his shoulders to lie down on the bed, she whispers: "Lean back Nawaki, or you don't want to see the breasts you love so much from your Sis ?"
Nawaki's eyes widened in surprise, after all, she asked before to call her differently when they're alone, however, the fact that she took the initiative to call herself Sis somehow made everything more exciting.
Still on his lap, Tsunade took off her nightdress. Although she looked very attractive wearing it, without it, she was spectacular, especially the moment the nightdress rubbed against her large breasts, making them sway a lot as soon as she took the nightdress off.
Cupping her breasts, Tsunade smirked, "Is this what you want, baby?"
"Damn it." Nawaki said softly, his eyes fixed on Tsunade's swollen pink nipples, "Sis, they're amazing."
"Fufu." Tsunade caressed her nipples with her fingernails, teasing herself with her light touch. She looked surprised at how hard her nipples got just from her touch from Nawaki watching, "Do you like Sis's tits? Do you want to suck your Sis's tits?"
"I want to do everything for my Sis." Nawaki said.
"Oh, you're a bad boy! You... oh yes!" Tsunade cried out with a moan like she was in a wet dream, just as Nawaki leaned forward, trapping his lips around her right nipples and sucking them hard into his mouth.
Nawaki growled softly around Tsunade's pink nub as she whimpered as his tongue swirled around her eager flesh.
Leaning back on the bed, Nawaki thought of something. As the position was a little bad, he puts his hands on her waist, putting her back on the bed. He licks his lips, he seems to sense her anxiety for him.
Her next actions proving that what he felt was real, Tsunade wrapped her fingers in his hair, pulling his head down to her right breast. Nawaki cooperates by opening his mouth, and sucks on her luscious pink nipple, making her moan and arch her back, pushing her breasts even further into her little brother's mouth.
The fingers of Nawaki's left hand find her other nipple, taking the nipple between his fingers and rolling it gently while his tongue teased and left a trail of saliva across her breast.
"Oh Nawaki!" Tsunade moans. She could feel the fluid seeping out of her pussy uncontrollably as she rocked her hips, she could feel his cock rubbing her steaming, sticky pussy.
Nawaki starts sucking her other nipple, quickly replacing his tongue with his fingers so as not to leave the other one unattended.
Tsunade lets out a long sigh as she squirms in satisfaction as her little brother enjoys her breasts and nipples.
"That's it baby, show me how much you want those tits." Tsunade moans, "Show Sis how much you want her."
The words seemed to come too easily and got her so excited, and even as Nawaki licked and sucked her nipples, she felt so good!
Nawaki's hand left her breasts and slid down her soft stomach. Tsunade swallowed hard as Nawaki's fingers reached the edge of her underwear which consisted of a white cloth that connected to another one that went around her beautiful legs.
Tsunade felt like she needed to do something, and lifting her hips, urging him on, "Go ahead honey, feel how wet I am, feel how much I want you!"
Nawaki didn't need to hear it twice. His fingers slipped inside her underwear and she moaned as his fingers slid across her sodden pussy lips.
"Oh Sis!" He moaned around her nipple, "You are so wet!"
"I am!" Tsunade exclaimed, rocking her hips in his hand, helping his fingers work the length of her dripping pussy, "I'm wet for you honey, I'm wet for my sexy little brother!"
Nawaki found her clit and her hips shuddered as his fingers rubbed her aching bud. She was breathing hard, her breasts heaving in his face and her hips moving as she writhed under his touch.
