Kim has to fit in a HUGE object in her "spy pocket" for a mission but she's doubting herself because the object is larger than her fist! Not one to give up Kim lubes up and works her way from one finger to her fist eventually giving herself the confidence to attempt to insert her equally huge butt plug as a test to see whether or not she could fit what she needs to. This process made her really horny though so she ends up vibrating herself to orgasm while the plug is inside her.
