Only with help

Anna realizes it wouldn't be fair to Ken if she quit now, she slowly starts sitting back up, his cock still half inside her, she has difficulty and Nicole grabs her to help her up "That's my girl, now put your hands on his chest and get back to work"

As Kens cock returns all the way in Anna struggles to comprehend much, all she knows is that she needs to move

Ken admires the site of a blonde on his cock again, Nicole hops on the bed and gets right up behind Anna, her breasts pressing hard against Anna's back, she wraps her arms around Anna and rests her chin right on her shoulder "Good Girl now I'm going to help you but you have to do the work"

With that said she slow guides Anna up almost off his cock and back down, when she reaches the bottom she gasps "I can't, he's too big"

Nicole kisses her shoulder and runs her tongue up her neck to her ear to whisper "Yes you can Baby Girl, I'm not going to let you quit, you can do this, come on"

They continue up and down for a few minutes, eventually Anna starts feeling very energetic and after a few more minutes Nicole isn't helping her anymore.

"There you go Champ, I knew you had it in you!"
