A/N: My first HitsuChiru, and my first lemon. Yachiru is supposed to be about 19 years old, which makes Toshiro 26.

Yachiru surpressed quiet moans as she was straddled by the older captain. She pressed her lips to his once again, parting her lips as he pushed his tongue into her mouth. Toshiro moaned as Yachiru's hand wandered toward his 'sweet spot'. She began to suck on his tongue as she unbuttoned his jeans. Toshiro knew he'd get his ass kicked if Kenpachi knew of this, but he didn't care.
"Yachiru-chan," he whispered in her ear as he reached up her shirt.
"Mm?" her tongue snaked across his lower lip.
"I love you."
"I love you too."
Toshiro broke the kiss only to remove her shirt. "And from this day, Yachiru Kusajishi," he whispered. "You are mine."
He unhooked her bra, pulling it off gently.
"Shiro-chan?" she asked softly.
"Yes, Yachiru-chan?"
"Is this gonna hurt?"
"I-I don't know. I h-hope not."
Toshiro removed her short skirt as well as her panties. As he did so, Yachiru was reaching for his boxers, which were, once she got ahold of them, pulled off quickly. She closed her eyes tightly and whined with pain as he pushed inside of her for the first time.
"I-I'm sorry," he managed to stutter out. "Th-this is hurting you."
"Sh-Shiro-chan," whispered Yachiru breathlessly, pressing her lips close to his ear. "Go faster."
Toshiro happily complied with the small girl's demands, pulling out of her then pushing back in quickly. All the pain which she had been feeling before had now became pleasure, as she moaned the older captain's name over and over. She moaned her loudest yet, as the captain released inside of her. He pulled out of her, finally, and lay beside her, hugging her close. Both their bodies were soaked with sweat and they were panting.
"Yachiru," he whispered after he caught his breath.
"Y-yeah?" she whispered in reply, still breathless.
"I love you. I always will."
"I love you too, Shiro-chan."
