Ask her to strip for you.

With just a smile she stood up from the bed and took a hold of your tie and used it to swing you down on the bed. She started moving her body in her tight dress, she would swing her self around leaning forward making her huge ass be placed in view for you. She shook it and twerked as much as she could... and her cock would fall out of her dress. She wore no underwear.

"ops" She said as she stood up to undo her dress. she let her dress fall down her body exposing it right before you and dancing with her ass. She looked over her shoulder with a grin on her face.

"Want to fuck this ass now boy?"
