I'm your girlfriend, and we just had an amazing date. But ... I can't stay at your house much longer. I have to be home before midnight. You note that I always seem to disappear when there's a full moon, but I brush that off - what do you think I am, a werewolf? Plus, it doesn't matter if I stay at your house anyway. You're abstinent and you're totally committed to remaining a virgin until marriage. But - you say you have a surprise for me. Intrigued, I decide to stay a few more minutes to find out what it is. Maybe you can't fuck me, but you CAN go down on me ... you impress me with your skills - how is a virgin so great at oral? You make me cum hard, but then I realize the time. I have to go! I run out of the house and straight home. Later, I'm hiding under the covers when you text me. You're worried, and you want to come over to check on me. I tell you to stay away, but you don't listen. Just before midnight, you show up at my house, only to discover me halfway through my transformation into a werewolf! My transformation will be complete at midnight, when the moon is at the highest point in the sky. And a full moon means I'm going into heat! I'll be desperate for cock and cum and unable to control my urges. You can't stay! I don't want you to give up on your oath - I know how important abstinence is to you. I beg you to leave me to suffer through my heat alone ... but you stay. We spend the night fucking in every position while I drool all over you and beg for cum. I can barely talk when I'm in heat - all I can do is grunt out over and over again the words "need cum, need cum". When the sun starts to come up, I'm finally satisfied. The next morning, I ask you ... are you going to stick around during all my heats, now?
