Instead of lotion, Ann can collect the cum of all her lovers in a cute little bottle (that has Joshy's face on it) and squeeze some out onto her body, face and hands as needed. Of course, this cum was slurped out of Ann by Joshy (with a straw) and put into the bottle by Joshy (also with a straw).
That way, she'll always be properly moisturized. And, of course, Joshy gets to slurp cum, spit cum, and see Ann rub cum on herself all the time out of a bottle with his face on it. Which is basically the same as Joshy himself cumming on Ann, but better.
