You grinned as you looked over at your dad. Maybe it was time to get him involved in the fun.
Concentrating on him, you used your power to change his asshole, making it stretchy enough to fit an entire head inside (and then some). Even more than that, you made it to where he actually felt empty when there wasn't a head inside him, making him yearn for it.
Still standing in the middle of the kitchen, holding your mom's smiling head while your cock leaked the last drops of cum from your orgasm, you stepped over to the table and placed your mom's head down on it.
"Hey dad, are you busy?" you asked him with a smirk.
He lowered his newspaper to look over at you. "No, why?"
"I was thinking maybe we could shove mom's head up your ass, that's all."
He looked down at his wife's head who smiled at him gleefully.
"I would actually like that very much, son," he replied.
Your mom giggled. "Well, you'll have to get naked then, honey."
Your dad smiled back at her before setting his paper down and standing up from his chair.
He wrapped his thumbs around the waistband of his pajama bottoms and pulled them to the ground, making his hardening manly cock flop around. This was the first time you've seen your dad's dick. It was only a little longer than yours, but was quite a bit fatter. His hairy balls were a little larger than your own, too.
Your dad actually stroked his dick a couple times while he stepped away from his chair.
"Place her down on the chair, Ben, would ya?" he requested.
You picked your mom's head back up and did as he said, placing her on the wooden seat and stepping back.
Your dad eagerly returned to the front of the seat and bent over, spreading his legs and revealing to your mom his enlarged dark hairy smelly asshole.
"Are you ready, Mere?" your dad asked with a smirk.
Your mom chuckled again. "Are you kidding, hun? I love being up your ass."
Taking that as permission, your dad began to lower himself down. Eventually, his big hairy sphincter was pressed up against the top of your mom's head.
You moved up to your dad and kneeled between his legs so you could get an up close view of your mom's head entering your dad's ass.
Your mom just looked at you with a loving smile as her husband began to insert her. He moaned as his asshole started to stretch out around the immense intruder.
His ass made a wet schlorping sound as the meaty ring finally managed to open up around your mom's head. Ever so slowly, your dad lowered himself, now fapping his own dick in one hand right in front of his son as he was pleasured by the sensations of his wife entering his rectum.
You watched, captivated, as your dad's gaping sphincter gradually swallowed your mom's head, the orifice noisily sliding down her face until she was in up to the nose.
"Oh honey," your mom moaned, her mouth and chin being the only remaining visible portion of her head. "This feels so good."
A few seconds later, the last of your mom's head was swallowed by your dad's ass as he finished sitting down onto the chair.
"Ahhhhh, fuck yeah," your dad sighed. "I missed having her in me so much."
Suddenly, he rose up from the chair and turned around to show you his ass. Your mom's hair was still spilling out of his asshole. A bit of the bottom of her neck was still poking out, as well.
"Son, if you wouldn't mind?" your dad asked you.
"Oh, uh, sure," you replied, gingerly reaching a hand up and placing it on the last bit of your mom's neck. You pushed inward and it, too, was swallowed inside. You kept pushing until the last of your mom's hair was fully inside your dad, which meant you were now essentially fisting him halfway up to the elbow.
"Well damn, son, at least buy me a drink first," your dad teased playfully.
The two of you laughed as you retracted your hand. His sphincter closed around your fist just before you managed to pull it out, resulting in a loud SCHLUMP! as you finally yanked it out. Your arm was now drenched in his smelly assjuice.
Your dad sat back down in his chair and sighed, continuing to jack himself off.
"Thanks a million, Ben, I forgot how good it felt to have something up my ass," your dad said, now gripping his big hairy balls with his free hand.
"No problem dad, it was really fun to watch," you responded, stroking your own exposed dick.
"What do you want to do now, sport?"
You pondered your options...
