Gasping out quite hard when you flick the tail, feeling it tickle her opening down there, making her blush even more when you found out. Looking at you with horror at the idea of you pushing it into her own flesh, grabbing and protecting her rear from you. "no no, I can do it Mistress!"<br/><br/>Panting out some while reaching behind her, grabbing the plug and slowly starting to push it into her own asshole. Crying out quite a bit from how uncomfortable this all is, while you get to watch her body shake some from how naughty this all is! Eventually she does pass through the resistance, to only cry out hard when the plug suddenly and violently slams past her asshole, firmly locked into her now. Thoroughly embarrassed over having to do that in front of you, while holding onto her ass and feeling very sore already.
