My best friend and I are 16. She came on vacation with my mom and step dad to Florida. We had a condo with a little pool and hot tub. My mom went out shopping and step dad was sleeping late. Me and my friend went in the hot tub then she went to take a shower.

When I went inside I caught my step father jerking off. He was in the hallway listening outside the bathroom where my friend was taking a shower. He was dressed but his fly was open and he was stroking his dick. I watched him and figured out why. I could hear my stupid friend, she was masturbating in the shower and moaning. She was using the hand held shower head. I used it too but I was quiet. She was loud. I heard when she came and so did my step dad who was right at the door.

I watched him from the end of hall. He didn't know I was there. I got to see him cum. He squinted and tried not to make any noise and came in his hand. I could see the first few little white spurts. My step dad is a perv. I told my friend who was embarrassed. She never used a shower head to masturbate before and got to into it.

I can't believe I saw my step father cum.
