Daddy walks in.

When you get ready to push your cock in; the door opens and there is your dad looking. You and your sister looks at each other and then covers up. What is weird tho is your dad doesn't have the shock look on his face or even a mad one at that. He has the look of lust. "What are you kids doing?" he sheepishly says. You and your sister look at each other in shock and back at your father. All you could say was "Umm". You both then see your Dad take his clothes off. He takes his boxers off and his 8" cock pops up into the air. It looks massive. Maybe bigger than yours you think. You look over at Emma and her jaw is wide open.

"So John and Emma are gonna have fun. I will join. Why don't yall get back in position and I will get into mine?" he says while walking closer to the bed. You and your sister look at each other and then we got back in position. With her in the doggie position and you behind her. Dad just stood there playing with his cock. You aligned Your cock up with your sisters pussy and slowly pushed in. She started moaning very loud. You started pushing in and out of her faster. She was really tight on your cock.

Dad walked up to her and placed his finger in her mouth and made her suck it for a few. This was getting extremely hot. She was getting even more wet. He then replaced his finger with his massive cock. She slurped his cock right into her mouth and started to suck away. The bed started creaking from me pounding her pussy from the back and dad pushing his cock down her throat. She was doing pretty good swallowing that massive cock.

After a few you felt her pussy tighten up more on your cock while she rode her orgasm. You felt you was getting close and You did promise her you would pull out. Maybe you can cum on her back or maybe you and dad can give her a facial.
