Alone for a bit

A short while later Vanessa left the apartment. The second the door was latched Lauren began masturbating. Lauren was always an avid self pleasurer, but she found sitting naked and embarrassed lathered in ointment all day somehow left her hornier then she'd ever been. She used one hand between her thighs over her smooth shave lips, the other working her rock hard nipples. She had three rapid orgasms before she heard her sister returning and stopped halfway to the fourth. Despite having just cum so much, Lauren still felt excited and frustrated.

Vanessa entered with a grocery bag. She looked to Lauren.

"Are you okay? You're sweating like a pig!" She exclaimed.

"I'm fine!" Lauren yelped. "What did you get?" Lauren asked, eager to change the subject.

"Just a few things. Anyways, it's time for your ointment." Vanessa said.

"Again!?" Lauren moped. Reluctantly she stood up.

"You know the drill." Vanessa said. "Arms out."

Lauren sighed, then pried her **** hands off herself. She stood butt naked, exposing herself to her sister. How had this happpened?!
