Wendy has been a family friend for years and John always knew her as Aunty. As a result he wasn't expecting her to be spying on him while he took a shower. Wendy stands at the door admiring what a big boy he has become especially as he starts playing with himself. When John sees her he asks her to get out but she has his towel. He gets out and tries to get it but she won't give it back until she has a feel herself. He stands there dripping wet with his "aunt" stroking his growing cock and when she starts sucking his throbbing dick he cums all over her massive cleavage!
