The startled cry made both Song Tian and Qin Ying turn their heads toward the doorway.
Qin Rong stood there, key in hand, her eyes wide and mouth agape, staring at Song Tian as he separated her sister's legs, with his hefty manhood right at the entrance, ready to plunge in.
"I, I, I'll come back later!"
Qin Rong said, hastily turning to leave.
Qin Ying let out a cry, pushed Song Tian away, and then bolted towards the bedroom.
Seeing Qin Ying lock the door, Song Tian got up, shot Qin Rong a glare, pulled her inside, and then closed the door behind them.
"You ruined my good time!" Song Tian said in a low voice.
"Hmph, I knew you were screwing my sister!" Qin Rong snapped angrily.
Song said, "I was just about to make my move, and then you had to come and screw it all up, you owe me!"
"I don't owe you shit, you—uh!"
Qin Rong gasped as Song Tian pushed her onto the couch, lifted her skirt, yanked down her panties, and spread her legs wide.
