This clip starts where Part 3 ended. Ace shoves a giant white squishy ball in her mouth. He tells her to not spit it out and he won't tape it in yet. She does what she is told. Ace continues taping her to the chair. Her elbows are taped together and then he tapes her arms up from her hands all the way to her shoulders. She is pretty much mummified to the chair at this point. He removes her gag, hoods her with a nylon, and then puts the gag back in and seals it in with gray tape. He then increases her breast bondage severity by wrapping them in clear tape. He flicks her nipples and gropes her bound tits. He then uses the gray tape and completely covers her head. he pulls her head back with the excess nylon, but soon unties it. He decides to add some black tape. He leaves her to endure the bondage in darkness and with limited hearing. After a while he ties her head back again. Riley moans and whimpers, but mostly she struggles to breathe. After what seems like an eternity, Ace returns. He asks her if she has any information for him and she nods "Yes". I included some footage at the end of Riley being released from her bondage. Riley is very expressive and all of her reactions are real.
