Smack smack...
The sound of flesh colliding filled the room incessantly.
Lin Tian was fast, and so was Buck.
But Buck could not afford to be slow while Lin Tian was fast.
Otherwise, forget four hours, they could withstand a whole day.
That would be extremely unfair.
Thus, the agreement Lin Tian drafted stated that either party must keep up with the other's actions.
Falling behind meant losing!
"Ah... ah..."
Wang Tong and Peng Rui's alternating moans also began to rise.
For the two sisters, this was also their first time being taken by different men in front of an audience.
It was so embarrassing!
But it was also incredibly exciting!
It granted them pleasure like they had never experienced before.
Seeing Lin Tian and Buck in competition, their cries also grew more vigorous.
Their moans were more lascivious than the last.
