Sheldon and Leonard are working on their Japanese while Amy hangs out. She suggests she might try, then proves that she’s quite good at learning languages. Sheldon tries to get their study session back on track, but eventually he takes off. Leonard tries to talk Amy into continuing their Japanese study session, but Amy cuts through the bullshit and suggests they just get it on as she takes off her shirt. Leonard points out that he has recently gotten with Penny and should probably not bang, but Amy points out that fellatio isn’t the same as fucking. Pushing Leonard down, Amy makes good on her promise to suck him off as Leonard basks in her expertise with her mouth.
