This is a masturbation simulator in which you play with a big-breasted maid who moves lukewarmly in Live2D, making her squirt and cum continuously with a powerful piston vibrator. She reacts to every operation in real time, and naughty animations are played. Please enjoy the way her whole body shakes abundantly by the insertion of the vibrator. Her reactions, breaths, and sound effects are perfectly synchronized with the operation. (There are no mechanically looping motions in this work. All motions are produced by special physical and emotional parameters tuned to sex.) A wide variety of parts can be switched, including ball gag, ear tag, swimsuit, milking machine, blindfold, glasses, squirting and spurting volume, dildo size, and tits, hips, and thighs. This time, we paid special attention to the movement of the insertion part and the expression of milking. The bottom part of her mouth shakes cutely as she sucks on the dildo, looking very delicious. You can drag and drag each part of the body to play with it, but you can take your play to the next level by using the multiple recording function. Since multiple recordings allow you to take overlapping shots, you can create your own original animations combining the movements of multiple parts, such as shaking the body in the first round of recording and manipulating the boobs in the second round of recording. Please try to create an animation of your own liking!
