Mistress Mercer grabs, squeezes, twists, slaps, tugs, pulls, and punches her bound and helpless sissy slave's balls until they are red and swollen, simultaneously bringing her to the point of no return with a mindblowing hand and blowjob. She spits on her face, slaps her, and verbally degrades her to her heart's content, knowing her slave is loving every minute of it. With no choice but to cum from the overwhelming mixture of pleasure, pain, and humiliation, slave Erica can no longer hold back a huge load... which is then shoved in her greedy slut mouth and down her throat, along with most of Mercer's hand.
