Nalla covered her mouth and gasped as she saw what was happening to Betsy.  She was powerless to move as she watched the physician being assaulted be the two strange, arachnid-like creatures while she hang suspended from webbing on the ceiling.  All the scientist could do was watch as her friend moaned around one of the tentacle like legs in her mouth.<br/><br/>Betsy and Nalla had met during training for the mission.  Both girls were the same age and shared similiar interests and became good friends.  To see her now was painful and threatened Nalla's sanity as she watched the aliens' strange appendages thrusting into her friend's orifices again and again.<br/><br/>Conflicting emotions were welling up inside Nalla as she stared transfixed as the violation continued.  She was obviously repulsed by what she was witnessing and wanted to help her friend.  At the same time, she was fascinated by the creatures.  The first alien lifeform she had ever seen.  She wanted to study it, note every detail of it's appearance and behaviour even as it was ravishing Betsy.  She also wanted to run away and find help before the creatures noticed her.   Most disturbing of all, Nalla felt arousal.  Her pussy was tingling and she could feel her nipples pressing into the fabric of her skin-tight uniform as sweat beaded on her exposed cleavage.  The scene was turning her on and she had visions of the creatures doing the same things to her.<br/><br/>Nalla shook her head.  She had to suppress such thoughts, the only thing she should be thinking about was helping Betsy.  There had to be something she could do.  She decided to run back to the medical bay.  There she would call for help before coming back to the cafeteria to do what she could for Betsy.<br/><br/>Then Nalla thought that maybe the rest of the crew had met a similiar fate.  What if there was no one else left to help?  Could she leave Betsy like this?  No, she couldn't.  Nalla grabbed a sharp knife from the serving station and pulled a fire extinguisher off the wall.  Perhaps the super-cool foam would disorient the creatures long enough for Nalla to free Betsy and get them both out of there.
