                         You be careful
                         An Erotic Story

     I looked down at where my son's prick had vanished halfway 
in his 12-year-old sister's furry little slit.  "Now you be 
careful, when you cum in her," I warned him.  "Make sure you 
ejaculate your sperm ALL the way up in your sister.  I don't want 
you two kids making a mess of the sheets."
     "Yes, Mom," responded the boy; sinking to the root in the 
child's belly.
     "When was your period?" I asked the girl, as her brother's 
strokes inside her became more urgent.
     "Uh ... I dunno ... a week or two ago ... I think," 
responded the girl.  Having her brother about to ejaculate inside 
her was kind of distracting, I guess.
     I heaved a sigh of relief.  One less thing to worry about.  
"Well, OK," I showed my relief to the kids.  "At least I don't 
have to worry about messes because of THAT."
     "Yes, Mom."
     "Now you kids be careful, when having sex.  I want you to 
promise me you won't be fucking on the bed, when your period is 
due, OK?"
     "Yes, Mom."
     Good kids I've raised.  All three of them.
     "Good," I responded.  "Now your little sister just finished 
HER period last week; so I want you two kids to show her how to 
fuck, just like you do.  OK?"
     "Uh ... uh ... UUUHHHHH!" my son shuddered and buried 
himself to the hilt in his sister's body; working to plant his 
sperm as far up in the child's womb as he could.  My daughter 
grabbed her brother close; wrapping her arms and legs around the 
boy as he jerked and shuddered and filled the child's womb with 
his seed.  I took that almost inarticulate groan as acquiescence.
     "And make SURE you ejaculate your sperm all the way up in 
HER too," I added, as I left the room.  "I don't want you kids 
making a mess of the bed, if you don't have to."
     "Yes, Mom."  This time barely a sigh; but I heard it.
