The Great Adventure of Mecha Engineer Ris

Ris is a beautiful mecha engineer. During her adventure, she is captured by an alien flying saucer. The aliens are instantly obsessed with her fair body. They use robotic arms to grope and squeeze her full breasts until milk flows out. Then they latch onto her nipples and suck hard while simultaneously thrusting mechanical fingers deep into her wet pussy. Ris trembles in pleasure and moans uncontrollably even as she tries to resist.
