They didn't have too much time as about twenty minutes had already passed since they entered the ship and the mainland wasn't that far from them. They only needed an hour and a half to reach it. When Wuxing said they only had time for one round, he wasn't lying. There was still other stuff he had to prepare before the final escape so they couldn't spend this entire time on themselves.
Because of that, he made sure to use the time they had together to the best of his ability. Dongmei was already ready from his previous teasings so he didn't prolong the foreplay as he had a habit of doing and prepared to enter her right away.
Both her bra and panties were taken off by him while his pants had been taken care of by Dongmei as her hands made sure to prepare his member for action, wrapping around it like an octopus which caught its prey. Her fingers skimming up and down, stroking it rigorously before aiming it for him, putting it straight inside of her.
