Nikki has prepared a big pool of custard for a naughty fantasy she always wanted to act out. She walks around it in a very sexy outfit, talking dirty about what she wants to do. Then sexily strips nude and starts dipping her toe in the pool and eventually getting in, covering herself in custard and talking about all the naughty things she wants to do. One of those things she fantasises about is getting fucked in it, so she invites you to get in there with her. She acts it out, being excited by your big cock... and asking you to fuck her, masturbating herself a little as she thinks about it... then she acts out giving you plenty of blowjob action and lots of fucking in different positions. To finish she cums after being fucked by you and then, after encouraging you to cum on her pretty face, she gets a major faceful of (fake) cum... being covered in cum making her fantasy complete.
Bit off topic it was the word Smash made me think of it, but we once had a restaurant manager who put mashed potato on the menu, we ordered the stuff, she offered to help, and returned to us a few minutes later, asking where the stuff for the mash was, we told her, and she replied 'what,under tthe potatoes?' Turns out she thought mashed potato was only made using packets of Smash (dried powder) and had never made them using potatoes.. she had worked in catering for fifteen years
