Hide in the hallway.

Katie was peeking on her sister fucking her girlfriend with a dick. After a few minutes she realized the she was stroking her own cock. She became confused for a second but then smiled and continued.

It seems that Suzie cummed again. She stopped and slided down along Jackie's shaft. Her cock fall down her stomach and released its load on Suzie's belly. Suzie's abdomen was already covered with it.

After she stoped ejaculating she started to move again. This time Jackie stopped her and Suzie moved down to the bed. Jackie stood up and aimed her dick to Suzie's mouth. She started to stroke it with one hand while grabbing Suzie's head with the other one. Suzie obediently opened her mouth right in time to catch the generous flow on Jackie's sperm. She closed her mouth and swallowed. Jackie continued cumming and covered with sperm Suzie's chin and chest ("I wouldn't lose the single possibility to cum on her glasses if I was Jackie." thought Katie).

Then Jackie lowered down and licked Suzie's sperm from her stomach.

"I love you, Suzie!" said Jackie when they were finished cleaning themselves by eating all sperm.

"I love you too!" whispered Suzie.

"I want to drink something. Do you want me to bring something to you?" asked Jackie.

"I'll bring you the water" said Suzie and made effort to stand up. ("She is really obliging lover" smiled Katie).

"No, relax. You've already worked hard." giggled Jackie. "I'll bring you something, dear."

Jackie kissed Suzie, took her bathrobe and walked to the hallway. Katie was fast enough to step in darker side of a hallway to avoid being caught. But she had time to see Suzie's ass when Suzie was turning to side - is was still open, like Jane's - and she silently moaned again.

Jackie left bright room and couldn't see Katie hiding behind the door. She slowly walked downstairs to the kitchen. What do you think the Katie did?
