For virtually her entire turn

Miia was really enjoying getting her revenge by edging Ms. Smith over and over. She did mix it up on occasion; running her coils between her breasts to give her a sort of boob-tail job while groping her breasts around it with her monsterous strength to exploit she couldn't physically harm Smith, spanking her wildly with her coils in the right places to bend her over, making her eat out her lamia pussy, but always just enough to deny the civil servant her orgasm.

Miia, on the other hand, had cum several times, making sure to clean herself on the trapped Civil servant. Papi and Centorea were masturbating to this, using a chair and her nipples respectively. Cerea looked at the wall clock after a while.

"Miss Miia, Master's allotted hour is almost over." She pointed at it, the lamia seeing she only had two minutes left.

"This was a lot of fun, but time to end this~" She said. Smith had just been coming off a break before Miia began her efforts to her most intense, using every form of stimulation she had at once. Spanking, tit groping, shoving Smith into her pussy, and diving her tail as deep as possible into the human's snatch.

"oooHHHHAAAAAH!" Smith cried out, cumming multiple times in those last two minutes, going blind in orgasmic bliss. But alas, Miia's turn was up. She begrudgingly uncoiled herself from Smith, depositing the exhausted civil servant on the floor.

"All yours, Papi. Have fun~!" She said, deciding that after this she could use a shower. The cum was already drying, and admittedly wasn't the most comfortable, but she'd be back after a quick rinse...
