Jon read Karyn's story starter but didn't bother reading the rest. He remembered it all too well.
"Well you're certainly a pretty enough witch.", Jon said. "Do I get to keep you?", he added with a teasing mock-eagerness.
"Aye, but 'tis I that shall keep you.", Karyn countered, and then cast a spell.
Jon found himself caught up and driven by the need to fully satisfy the beautiful witch that straddled him.
Jon felt himself recovering and hardening in an unnatural instant.
"Thou art enchanted until thou dost fully please me.", Karyn said as Jon found himself valiantly working to fulfill the geas Karyn had laid.
Jon couldn't stop, even when he wanted to. Until he was done.
"Witch.", he managed to get out, despite being too drained to move. He wanted to sleep for a week.
A very satisfied Karyn gently cooed to her lover, "Thou hast been hagridden, if thou couldst call me a hag in anything but jest."
Karyn's mother picked that instant to knock on the door and call from the other side, "Ok you two lovebirds have had your time together. Now come downstairs and do some chores and finish your homework before I have to come in there."
