She uses her tongue

"Now, remember to breathe out."

"What do you mea…"

Before Gamer Girl could finish Ruko slams her pussy into her face, smothering her as Ruko slams her face into Masato's pussy.

Making sure to stick her tongue way out as she practiced with other people. She made to grab Masato's legs and pull them, bending her basically as she starts to vibrate her tongue inside Masato's pussy.

Masato screams underneath Ruko's ass as Ruko really goes to work on her pussy and sticking a few more fingers in her ass.

Masato soon can't take anymore and starts to tap.

Ruko smiles and pull her mouth off her, "Cool, huh? I learned that vibrating tongue trick off Kanya, with improvising the bending of back and fingers in asshole as I figured with me occupy all your holes, there's no way someone cannot tap out. Genius, huh?"

Masato is still tapping out as Ruko is still on her.

"Oh, oops, forgot." She got off as Masato lies dazed on the floor of her friend's dressing room.

"So…" Ruko asks, "What do you think?"

"That…" Masato says, still seeing stars, "That might work."
