A man and a woman abstain from sex for a month before going on a trip to a tropical island. As soon as they arrive at a deserted beach, they can't contain their pent-up sexual desire and devour each other's lips. She lovingly sucks one dick, strokes it, inserts it, and ejaculates a large amount... After a clean-up blowjob, she inserts the dick again, using her whole body to make it erect again and lead it to ejaculation. No matter how many times he ejaculates or cums, it's never enough, so they rub their genitals against each other over and over again. When they get back to the hotel, they entwine their bodies again and desire each other until their balls are empty! I've never seen Saki like this...
