"Looks like you need a harsher lesson and punishment."
Jenna put even more weight on her foot, forcing Ethan to let out a pained groan and grab onto her leg while lying down in an attempt to ease the pressure on his junk.
"Please!... ah...slow..it's too much!"
Ethan said helplessly, unable to move Jenna's crushing foot away from his genitals.
Now, even the point of her long heel was painfully digging into his balls while the sole pressed his hard-as-wood erection into his lower abdomen.
A vicious smile appeared on Jenna's red lips as she said to Ethan,
"This is nothing. Remember, you are a slave. Learn to embrace the pain and humiliation. That's where the true pleasure of being a slave is."
Ethan stared in shock up at Jenna as the painful pressure on his dick and balls grew.
He realized, despite being in pain, that his erection got harder, trying to resist the weight of her foot.
