Some pay back

You finally got your sister in your room and she was getting busy worshipping your cock. "Holy shit, how did your cock get this big? "Emily said while giving your huge cock a couple of strokes while rubbing her face on it. "Fuck, I could suck on this all day," She said before putting the tip into her mouth. The answer to that question would never come since you hade something in mind for her.

"I think that it was about time that I put you in your place bitch," You said while grabbing her hair and thrusting forward a bit into your sister's mouth. You got single gawk that turned into her sputtering on your length in response to your cock sinking into her throat for a second before pulling back and getting a rhythm going. With every thrust, you got deeper into her throat, and you could feel it coiling around you the closer you got to her gag reflex.

Then with one last thrust, you get most of your cock into her throat and she gags and sputters onto your cock while tears fell down her face ruining the makeup that she had put on this morning. "Fuck, that feels so good," You say while holding her head down not letting her come up for air.

After about thirty seconds you finally let her go and she falls back with a pop off of your cock, and was trying her best to catch her breath. "I-It felt like you weren't going to let go," Emily said while gasping for air.

"Almost didn't, that throat was amazing," you said while giving yourself a few strokes while remembering the feel of your sister **** on your cock.

You then pick her up off the floor with strength that you did not have before this transformation and threw her onto your bed. "Get on all fours, I'm going to take you," You said while getting hard in no time, there was really no downtime. Not that you or your sister were going to complain.

"Y-You have to be gentle," Emily said while getting on all fours and positioning herself near your cock that pointing at her.

"Fuck," You groan out while getting a good look at your sister's bubble but that was on display. To think that this stupid slut would **** you every day without at least letting you get some of that tight ass. It was time to let her know that you wouldn't stand for this.

"Hng," Emily whined out while you pressed the tip of your cock onto her entrance and worked your way into her overused snatch. Her folds were no longer pristine, but damn did it feel good to be wrapped your cock up into her warmth. "Fuuuuuuuck!" Your sister moaned out as her back arched and her face fell onto a pillow. "Your fucking huge," She said while you continued to stretch out that pussy ruining it.

"Get ready bitch," You said while grabbing a hold of her hair and making sure that your feet were in place for the fucking that was about to take place.
