   Summary

   Tweek Tweak found himself sent back to St. Leonard's Hospital to carry a pregnancy in secret that his parents wanted gone. The plan was simple: survive the birth, sign the papers, hand the pups to a family that could love them and then return to his normal life in his parents coffee shop and then get married to a nice Alpha who need not ever know any of this happened.

   But Dr Craig Tucker has a different plan... his research into the determination and selection of secondary sex assignment has driven him crazy and here in his grasp is the perfect patient zero. All he needs is for his friend, colleague and part time lover Dr Kyle Broflovski to forget about morals and let him... experiment.
