"Oh my god, you are making me so hot."
You tell her that she is beautiful and making you horny too.
"I don't know if I can sleep next to you all night, without touching you. I think you need to restrain me right now before I jump on top of you."
Feeling suddenly powerful, you tell her to beg you to tie her up.
"Please, please keep me from pleasuring myself. I need it, please."
