Overview:

This is a masturbation simulator where you can play with a big-breasted girl who moves lukewarmly in Live2D by inserting her into a very thick dildo that is bigger than her torso and stirring it up.
She reacts to every operation in real time, and naughty animations are played back.
Enjoy how her belly swells up by insertion.
We pursued realistic fantasy expressions such as insertion from free fall and recoil by sudden insertion.
Her reactions, breathing and sound effects are perfectly synchronized with the operation.
