LESBIAN ORGASMS WITH TEEN STEP-SISTER (18) IN THE SHOWER?!

Actually, my stepsister just wanted to stay over at my home for the first time today. I'm completely alone with her and show the shy teen the bathroom. She wants to take a shower, but I just go with her and take my clothes off. I just want to help her and show her how to turn on the water and where the shampoo is. The sweetie likes it, and then I kiss her passionately. She starts to moan softly and gets horny. I let the warm water run over her naked skinny body and lather her up with shampoo. I'm very thorough and wash her wet pussy and her small tits. I feel how wet she is between her legs and massage her wet pussy. I want to finger her and she wants to touch and pamper my pussy. We are getting wetter and hornier and moaning more and more. Will we both experience a hot lesbian orgasm in the shower today?
