At the end of the two weeks she was visited again by the nurse and received injections for the next three mornings. At the same time all the programs on the TV and the books and magazines changed. They all now contained material to do with sex, sex between couples, sex in groups, sex with animals, in fact sex in any form.

Over the following week Helen noticed that the staff that brought her meals started to try and touch her or fondle her every time they came in. During one of the nurse's visits she noticed the nurse's nipples were obviously quite erect and the nurse also started to rub Helen. The nurse realised what she was doing and quickly ran out of the room, returning a few minutes later with a face mask on, to continue the check up. Helen asked her what was going on and was told that phase two was progressing well.

It was about the same time that Helen noticed that her A cup bras were becoming rather tight. Also her nipples seemed to be very tender and sensitive. Every morning now the nurse came in wearing her face mask (as did all the staff now) and inspected Helen's breasts and nipples. It was on the sixth day since the injections that Helen woke up feeling very aroused and noticed her nipples had swollen to be nearly one inch long and half an inch in diameter. She touched them to see if they were really her and was shocked by the exquisite sensation that immediately sparked from her nipples, throughout her breasts and down to her vagina and clit. The feeling was so good that just using one finger to lightly rub along the length of her nipples almost caused her to cum.

As soon as the nurse arrived Helen asked ''What is happening to me? My nipples are so big and sensitive.'

The nurse replied, 'This is just phase two progressing. Once this is over you will have DD breasts, maybe even an E, with nipples as sensitive as most women's aroused clits. Your breasts will also be superbly sensitive to sexual stimulation. The last woman we had in here could cum just by having someone blow gently over her breasts and nipples. It was great watching her outside topless in a breeze!'

'You will find over the next two or three days that anything touching your aureole or nipples will make you feel aroused and if there is any movement or other stimulation you will cum. You will have about two weeks to get used to this before phase three begins.'

'Do you mean I will be like this from now on?' screamed Helen.

'Oh no, they will get slightly more sensitive over the next month or so before they stabilize. Then that will be how it will be for the rest of your life. I see your breasts are nearly complete. Please take your top and bra off so that I can inspect your development.'

Helen stripped off her top and bra and went to lay down. 'No, please stand and put your arms down by your sides.' said the nurse.

'Wow, you sure are developing well - not an inch of droop! They must be a D cup now. Here, let's just try an experiment.'

On saying this, the nurse quickly started to fondle Helen's breasts.

'Ohh... Ohh' cried Helen, nearly collapsing due to the wonderful sensations. She began panting as the nurse continued to fondle her breasts.

'Yes, you sure are coming on fine. Let's see what happens if I suck on your nipples.'

Helen looked on in despair as the nurse bent her head down and took Helen's left nipple into her mouth and started to suck.

'Oh my god, I'm cumming' screamed Helen as she grabbed the nurse for support.

The nurse spent the next few minutes sucking and playing with Helen's nipples causing her to have almost continuous orgasms as she clung to the nurse for dear life.

'OK, that's enough. God, your nipples are the biggest I've seen here.' said the nurse as she moved away from Helen.

'They must be nearly an inch and a half long! Just one more test.'

The nurse then reached forward and using just one finger on each hand rubbed once around the base of each nipple, along it's length and back to the base. This caused Helen to drop to the floor, cuming better than she had ever done before in her life. Once she reached the floor she grabbed her breasts and nipples to make the pleasure continue.

'Don't wear them out or pull them off, I will come back in ten days time to check up on you and begin phase three.' called the nurse as she left.

Over the next ten days, Helen recalls only snatches of what happened as she played with her breasts and nipples. When the staff brought her meals they seemed to take great pleasure in stroking her nipples once they had delivered her food or before they left having cleaned the room. Helen could not bear to have anything touch her breasts or nipples as it just caused her arousal to rise uncontrollably. She spent most of her time masturbating her breasts until exhaustion drove her to sleep.

By the end of the period she was just learning how to have some control over her behaviour. Her breasts were soft to touch, but had absolutely no droop and nipples that were always at least three quarters of an inch long, except when she was aroused, when they extended to about an inch and a half.

Helen's breasts look amazing, they are longer than they are wide, about half as much again. Much as most other women's breasts look when they are hanging down while they are on their knees. Helen's are like this all the time sticking straight out from her chest with her big red nipples sticking out like nose cones.
