I've been teasing you all day in front of everyone, lifting up my arms and stretching, showing off my smooth sexy armpits. I know what it does to you and I keep doing it. You go to a room in the back of our house to jerk off and a few minutes later, I meet you there. I continue to tease you, reminding you how taboo it is to stoke while thinking about your stepsister, especially right in front of her. I put my new cream deodorant on, rubbing it into my smooth skin, then I take my top off. Encouraging you to cum for me, I start giving you a handjob myself and allow you to cum all over my sexy pits just like you were imagining.
