Pam takes things a bit further with her training when she uses some of the growth chemical to make herself into a giantess in her bedroom in this next chapter of Pam's Training!

Continuing where we left the previous chapter off, Ivan was down at his step-aunt's feet worshiping them as she laid back to rest. She begins to grow bored of this and takes her little guy upstairs, putting him in her shirt against her boob as she walks up the stairs. When she lays down on the bed he crawls out, only to stumble onto her crotch area. Pam loves having her tiny man here and rubs him against her pants as she begins to get wet. Starting to feel hot, she quickly runs into the bathroom and comes back out naked holding two bottles. She explains to Ivan that one is the shrinking formula and the other is used to grow. Wanting to demonstrate it herself, she takes a sip of the growth formula and grows to twice her size, crouching down as the ceiling becomes too short for her. The two of them have fun together, using Ivan as a toy while the giantess touches herself. She drops him onto her mouth and licks all over his body until he cums into her mouth. Upset with how he handled things, Pam decides to grow herself even larger, ending up 3 times her normal size in her tiny bedroom. They continue to have fun until she wants to return to normal. Afterwards, she dumps some of the shrinking formula onto Ivan, shrinking him to only an inch tall as she puts him into her pussy, sealing him away for the next few hours as she slips up her underwear.
