章 71: I don't care, just put it in (R-18)

'As always, my brother's cum is the best❤️'

Liana thought, licking the remnants of cum off her lips with her tongue with relish.

"Thanks for the treat, brother."

The sight of the panting girl in front of him, devouring his cum like the world's most delicious dessert, made Rain's cock even harder than before.

"I still feel empty in some places, I hope you can help me with that~"

With those words, she teasingly ran her hand over her pussy.

"Anything for my favorite sister."

Rain showed a loving smile and touched her hips. But before he did anything else, the voice of the system sounded in his head.
