I let my dad f*** my gf while my mom was out for the day at work. And my gf gave her consent for this. I let them do it in my room so that there wouldn’t be any proof in my parents bed. It was the middle of the day and we sort of played a little cuckold game. I told my gf to wear a red dress that showed her thighs, and told her to sit next to my dad on the couch. And my dad was free to do what he wanted. All in front of me. So they had a whole flirty conversation and after a few minutes they told me they were going up stairs. It wasn’t long before I heard my gf moaning and her cheeks being clapped. I watched from the slightly open door which my dad did on purpose so I could see, it was part of the deal. They fucked for like 20 minutes and just by watching I could feel the precum on my pants. Well my dad ended up c****** deep inside her and still had enough to drip on my sheets. After that my dad jumped in the shower while my gf was there on my bed t****** facing up, and I pulled my d*** out and used my dads c** as a lubricator and started f****** her again. I hugged her so tight while I fucked her and told her I loved her. She said she loved me to. This is our little secret. I’m thinking of allowing my gf out on dates with my dad when my mom isn’t home. I have no problem sharing with my old man.
