Tied face down, gagged and helpless on the bed!

Annabelle's step father is in town and staying at a local hotel. She goes there to visit and sees a woman leave his room. She goes in to find her step father is in the restroom. So she goes over to the bed and sits to wait for him. There, she finds a pair of women's panties. Having seen, the women leave the room and finding these panties, it doesn't take Annabelle too long to figure out, her step dad is cheating on her mother. When the man comes out, she confronts him about this. Then she picks up her cell phone to call her mother so she can report this. Step dad cannot let this happen. So he grabs Annabelle and ties her up. To keep her quiet in case her mom calls back, he stuffs and tapes a gag in her mouth. Annabelle struggles bound and gagged on the bed. But here is the the problem. This girl is very kinky and is very turned on by this. When her skirt rises, the man notices welts and bruises on Annabelle's fanny. Seeing this and the lack of anger for her situation, Step Dad now knows what a kinky girl she is. As things evolve, Annabelle now finds herself tied spread eagle and face down on the bed. Then her phone rings. It is her mother calling back. No longer gagged, Annabelle talks on the phone to her mother, to let her know things are great. After she hangs up, Annabelle tells her step dad to gag her again, so she can scream loud when he fucks her.
