it was about 7 o'clock and Emma gave a sudden lunge bringing both her legs up towards her tummy and sitting forward head thrown back.

I jumped up wondering what the hell had happened. "What the fuck!" I said.

Emma slowly pushed back the bedcover and began to straighten her self out

As she slowly begasn to straighten her legs the problem started to become apparent, protruding from between her slit was red triangular mound that was her engorged clitoris. Her clit was about 4 or 5 times it's normal size and ultra sensitive. It was the bed clothes brushing against it which caused her to spasm so violently.

It waas facinating to look at, the skin of her hood pulled tightly back and a small penile head like shape sticking out from below it.

Underwear today is totally out of the question. She has had to settle for short loose skirt and finds it impossible to close her legs fully.

Should be interesting as she has to visit with family later today. 

What caused this?

The previous day I was out all day until late, she was home alone and decided to get out some of her toys, She must have been playing with herself for hours and this has been the result.

This is not the first time she's had this affliction she has had it a few times the worst case taking 3 days for her clit to return to it's usual size, that was following a Christmas  party.
