[This was a custom request] You walk in on your (very sexy) nanny while she's on the toilet. She tells you to leave her alone while she's peeing but you explain that you really need to go too. She looks at you with a glint in her eye and asks if you want to play a fun game. She explains that the game is called cross the streams and that you have to pee in between her legs while she pees to try to hit her stream with yours. You excitedly agree - you love games! You begin to release your bladder between her legs but before she barely has time to start peeing, you accidentally hit her pussy with your pee. She begins to act very strangely and rubs herself between her legs, playing with your urine. She encourages you to continue and try to hit the same spot again so you do as you're told. She starts to masturbate while you cover her pussy with your pee, until eventually she shudders and stops - explaining that you just made her feel a little tingly, is all. She feels bad that you didn't get to play your game so she offers to pee all over your cock too. She grabs your cock to hold it underneath her pussy while she releases a huge stream of hot urine all over your cock. You begin to feel it hardening in her hand as her warm piss covers you. She notices your swelling cock and teases the lips of her pussy with it a little. She uses the piss all over your cock to begin stroking you as she leans in and tells you how she wants you to feel tingly too. She tells you to let your body take over and if you feel like something is going to come out of you, just let go. You close your eyes and enjoy her hand around your wet cock, she leans in and whispers how she knows she's your favorite Nanny and that you should give her all of your liquids. When you finally cum, she aims your cock toward her pussy again and lets your thick seed dribble all over her pee-covered pussy. She rubs it into herself and lets go of your drained cock. While a glob of your cum runs down between her lips, she innocently tells you to help yourself to some cookies downstairs while she tidies up, as though nothing had ever happened.
