Cora sat on Freyja's penis for several moments as her breasts were rubbed.  She liked the feeling of such fullness and warmth.  After a while her belly began to ache and her arrousal deminish.  It was time to try and move.  "I... I think I'll move now," she said.  She brased herself.  Freyja had warned her not to spill any seed.  She must be sure not to.  Cora was unsure what the consequences might be, but she knew she didn't want to make this fine lady mad.  She started to stand up, pushing herself off the huge penis.  It hurt as she moved, but she didn't want to go too fast for fear she might allow some cum to spill.  She felt the notch of her tip hit her sphincter... and new she was almost there.  She clenched her anus as tight as she could... even though it hurt... and pushed up and off.  She felt warmth and moisture at her anus... but didn't think more than a few drops got out.<br/><br/>She breathed a little easier... and layed down on her bed roll.  Holding her tummy, which was still so full of seed.  "ohhhh....mmm" she moaned.  It was hard to hold her sphincter tightly shut.  She hoped that would get easier.
