A Airplane Cup with double unlimited stimulation features. The front and rear sections use different elastic materials, and the extreme sense of tightness in the front section and softness in the back section create a strong sense of contrast! ! Delicate folds squeeze your penis! If it enters the deepest bottom, it will be squeezed and tightened! The mochi-like depth gently wraps the glans and slowly stimulates ejaculation! Taste both strong and kind feelings!
