"Yes."
His firm answer rang out, leaving no room for doubt.
"But doing it here?"
Liana looked around at the several desks with stacks of papers on them that the teachers usually sat at when she came here on various errands.
In response to her hesitation, Rain moved closer to her, his hand slipping under her skirt and possessively squeezing her ass.
"You don't want that?"
Rain whispered in her ear in an eager, husky voice that sent shivers through Liana's skin.
"No... if that's what you want, I want it too."
Liana relaxed as the remnants of her doubts dissolved in his hot hands. Feeling that signal from her body, Rain grabbed her ass and lifted her up, pulling her against him.
*Chuuuuppp~*
Having already missed these lips, he began to suck them greedily. His sister responded willingly with her tongue as her hands caressed his muscular back.
