Mommy sneaks into your room during your afternoon nap. She wants to make you feel good after you've been such a good boy for mommy. She takes your crinkly diaper off, only to find you've grown a lot bigger than what she remembered... especially when you have a big fat stiffy all of a sudden. Mommy tells you to stay quiet as she shows you how her mouth can give you special tingles on your little boy parts. She is really happy with how big you've grown, and tells you how much fun she is having playing with you. Mommy keeps using her mouth on your throbbing penis, and soon makes you have big cummies! She quickly wraps you back up into your diaper to contain the big mess you've just made. Mommy is excited to play with you again soon sweetie!
