Step daughter gets caught and watched

I caught my step daughter being wounded by her boyfriend.

This is a true story.
I caught my step daughter and her boyfriend having sex.
I had been out behind the house working in my vegetable garden and tending to some other outside chores. As I came back around front to take a break and cool off, I noticed her boyfriend's car parked behind her car. I didnt think much of it since they were always together that summer. I went in the house and got a cold drink only to realize my step daughter and her man are nowhere to be seen. Thinking they went for a walk, i kicked back in front of the fan and relaxed awhile. While I sat there I kept hearing little noises and then heard a loud moan from inside the house. Getting up I quietly crept around the house trying to figure out what it was I had heard. When I got to my daughter's room, i noticed the door was partially open and her boyfriend was fucking the hell out of her. She was moaning pretty good cause he was speeding up and really slamming it home. I had seen my daughter in conservative bathing suits before but hadn't seen her in anything less. I have to say she had a bangin body. She's short n stacked. Less than 5ft tall with double Ds and from what I could make out a shaved pussy. They had left the light on so I could see she was on her back and he had pushed her legs back to her ears so he could pound straight down into her.
She must have been really into it cause she had cream running down her ass. She always hinted to her mom that he was well endowed and im not sure on the length but it was definitely much thicker than her wrist and was stretching her pretty good or her pussy was very tight cause her pussy lips had a hell of a grip on it.
I watched them go at it for a while while trying not to whip out my dick for a wank right there.
This went on for a few more minutes when I saw him slam down in as deep as he could go and then start pumping her full of cum. He fell off of her and she got up and crouched in front of him with her ass pointed my way and started licking their combined juices off of him. She was positioned in a way I got a clear view of her bright pink freshly fucked innie pussy with cum drooling out of it. She switched to a short bj to get him hard again then mounted him cowgirl and started riding him for all he was worth. His cum was still coming out of her with every thrust.
At one point he grabbed her ass and pulled her cheeks apart so far that her pussy lips pulled apart too and he really started slamming his cock up into her.
I'm glad he was being so wild because at one point he slipped out and I got a good look at her gaped open pussy still leaking cum. At that point she turned around and leaned back on top of him and I got a full view of her pussy lips stretched around his thick cock. She started moaning loud saying she was cumming and was playing with her clit while he hammered up into her. He didnt last much longer before I saw him clench up and shoot another load into her. She pulled off of him and started scooping his cum out with her fingers and licking them off. At this point I backed off so as not to get caught by her and went back to the living room to wait.
When they eventually came out I told them "if ur gonna have sex, don't do it in the house. And if ur gonna sneak some then you'd better make sure no one is home first". They said they didnt know I was home and I pointed out my truck out front. She ran to the bathroom embarrassed and he looked over at me and asked "did you enjoy the show?" When I acted confused he said "I saw you in the doorway watching us. I didnt tell her. How much had you seen?" I told him "just before the the first creampie when you had her legs up by her ears.". He kinda chuckled and said "that wasn't the first one, that was the second. I told her I was gonna make sure she was leaking my cum for the rest of the day." Then he added "thats why I spread her open to give you a good view and why I told her to ride me reverse and lay back.". I asked "why would you want her step dad to see her like that?" And he replied "because she said no to daddy daughter role play with me so I thought I'd get it vicariously through you. Even if she was unaware of it and frankly that was hot as hell."
At that point she came out of the bathroom and drug him out the door. When I was sure they were gone I went and had a much needed wank and went back out to the garden. Later that night I fucked my wife while imagining it was her daughter i was fucking and cumming into and that was the first time I made gave her a bed soaking squirt. We went for so long she had to tell me enough and she couldn't walk very well the next day .
