Fuck your ass (Cum Inflation)

“Okay, can I fuck your ass, dad?”

Your father begins to bite his lip sensually with desire before answering, “sure son, you can fuck my ass.”

Without hesitation you pull out your massive monster cock of a dick that you have from changing yourself. Your father stares at it with oust and fear. You then grab your father and pin him down, to which he resists you pinning him down despite the look of lust being present on his face. You smack his face with your massive dick and turn him around onto his stomach and grab ahold of his plump ass, hot dogging your dick between those hot buns of his.

You begin to tease him while somewhat pleasuring yourself by trotting his ass. After half an hour, he looks ready to explode from the teasing, so to release that, you pull your dick back and press it against his pretty pink pucker and thrust your massive dick into his extremely tight asshole, so tight it feels like it is trying to crush your dick but it is too massive to do so.

“Fuck! Dad, you asshole is so tight!”

You father screams out in great pain due to him being an anal virgin and you making it worst by making his asshole tighter than normal.

After another hour of thrusting into him with your massive 16 inch (40.64 centimeter) long dick, your father begins to moan out in pained pleasure.

“Dad, I am going to go all out now!”

“Stop calling me dad, call me by my name, Sam!”

You thrust even harder into your father. His asshole is just so irresistibly tight due to your machinations. You continue to watch his ass jiggle a bit ass you fuck him, to which a though comes up in your head. You begin to spank his ass and watch it jiggle more, causing you to spank it more, with even greater vigor and even more speed. After another 7 hours of so of fucking your father, his gives you a facial expression that you know as an ahegao.

“I am going to cum father!”

“C-c-cum, imshid mwe, sjahn!”

His lack of control with being able to speak pushes you even further and you give one final thrust into his asshole and release the load you have been building from not ever masturbating for nearly a decade and holding back the build up from fucking him for over eight hours straight.

“Argh! I am cumming into your moist and hot bussy, Sam!

You turn your father around to stare into his eyes. You look down and see your load that you’re releasing into him build and build. His stomach begins to bulge and distend. You are filling his stomach some much with your cum his stomach is bulging so much he looks like he could be several months pregnant. But given you continued to cum more, you see the expression on your father’s face with his cheeks bulging, you spurt one more stream of cum and your father begins to vomit a fountain of cum which just covers himself in your cum, and covering the front of your hips as well, given you are still connected to him.

It was so hot for you, you got hard again in your dad and begin to fuck him and cum in him until night time, to which you got tired and went to sleep on your bed with him in your arms and your dick erect, sitting inside him, with him covered in your cum.
