Finally, with both her hands and mouth, Li Na served Zhao Tienan comfortably after one hour and eight minutes.
"Ah, I'm so tired, my tongue is numb, and both my arms are so sore they're numb too."
"Doctor Zhao, how do you manage to do this? How can you be so strong?"
Li Na was exhausted, her entire body limp, and she lay weak and innocent on Zhao Tienan's chest, her body drenched in fragrant sweat.
"Are you already losing your nerve?"
"Director Li, it's three days and four nights, this is just the beginning and the main course hasn't even been served yet."
Zhao Tienan held Li Na's sexy little chin and admired with a smirk the face of a mature and beautiful woman.
"Yes, Doctor Zhao, why don't you just let me go?"
"If this keeps up, I'm afraid my body won't be able to take it..."
Li Na sniffled, then began to act coy, lying on Zhao Tienan's body.
"Dream on!"
"Who told you to agree so readily at the beginning, and now you want to go back on it? Too late."
