You lie to Karen

You don't find a rubber and neither does she. She tells you she is worried that Amber shouldn't be alone with Bobby. You tell her you have known Bobby all your life and he cares about Amber (actually you know he is a dog). You get her drunk after an hour. Soon after that you are both naked. You check her thoughts and know she is ready to fuck but still afraid of having a baby.

You get into position and get ready to fuck her. She tells you she can't as she is fertile. You promise her you will pull out. You care about her and her feelings and would never do anything that she didn't want to. You probe her mind. She really is a virgin and you are the first guy to do her. She has a few minor orgasms as you build to the big one. Your experience makes her first time feel good. She explodes in ecstasy as you pile drive your cock all the way in and dump your potent sperm in her pussy.

"You fucking bastard!! You came in me after promising not to!!", Karen screams at you.

She grabs her clothes and rushes out of the room. You follow her but stop just past the door and just avoiding running Karen over. She is standing motionless and soundless, staring at what she sees ahead.
