Within IMVU's expansive 3D universe, a neighbor's crush simmers, boiling over into explicit virtual sex. The avatars, brimming with desire, engage in raunchy foreplay before the neighbor suggests, "Let's make a baby." They proceed to a detailed, lewd encounter, with the avatar's body contorting to the user's commands. The scene is explicit, with graphic animations and sounds, culminating in a mutual, virtual orgasm as they create a new life in this digital sandbox.
