yes, but not by choice

Sakura feels the serum Hinata gave her earlier spring into action, making her incredibly horny and in need of attention. Sakura furiously nods and Shikamaru releases her from the shadow technique, allowing her to nuzzle her head to his groin, clumsily working his erect cock into the ring gag where she uses her tongue to message his length.

"that is better" Shikamaru sighs enjoying the message from Sakura's tongue.

Sakura pulls back and grumbles at Shikamaru, trying to tell him to remove the gag, he seems to get it and soon Sakura is giving him a full on blowjob, gag free. It isn't long before she feels him erupt in her mouth. Sakura swallows the whole load as Shikamaru pulls out, Sakura immediately starts licking him clean.

"geez, you really are enjoying this aren't you" Shikamaru says stroking Sakura's hair "why don't we get you home and finish things there?"

Sakura stops licking at this point and looks at Shikamaru.
