Part 2. Eighteen year old Tilly had just started college and was looking for some part time work. She answered an advert for a sitter and even though she has not done that before she applied and got the job. She was nervous to start with but imagine her extra stress out when she found out it was an AB boy. But she soon got into playing with him and his toys. Then his diaper needed to be changed and there was no way out of it. Not only did she have to deal with an icky wet diaper but she had to wipe and powder his private parts. Being from a small country town she was still a virgin and never even seen a penis before much less handled one. And this penis became a big stiffy in her hand while she was cleaning it. She gives nervous little giggles but gets on with the job.
