What does Helen Do Next?
Helen Wants to Fuck Sam’s Ass
"Take the lead?" you said as you slowly began to back away from your mother.
"I've been reading lots of articles online. I wanted to know the best way to deal with my hard problem."
You didn't like where this was going. You could see a dribble of precum already leaking from the head of your mom's massive cock.
"I read that the best place to put your cock is in the ass."
"Mom, no! You are not putting that in my ass!"
"Let mama take good care of you, Sammy," she cooed.
As you were trying to put some distance between yourself and your mom, you stumbled backwards onto the guest room bed. Before you could get back on your feet, your mom had closed the distance between you and pinned you down on the edge of the bed. You could feel her hot breath coming out in steamy exhales on your face; her washboard abs pressed firmly against your comparatively slimmer stomach; and worst of all, her thick member was pressing sloppily against your inner thigh. You could feel a trail of precum oozing against your leg.
"Let's get you out of those clothes," she hummed.
Not wanting to experience an anal **** from your mother, you squirmed under her powerful muscles and managed to slip between her legs, but before you could make a run for it, your mother's massive ass slammed down on your back and pinned you on the ground.
"Ah, ah, ah! Not until we're finished," your mom teased.
You struggled to escape from under her massive butt. Suddenly, you felt a slight draft. With you firmly secured beneath her, your mom began the work of removing your pants. You tried to resist, but her position on top of you afforded you minimal wiggle room.
"And they're off," your mom announced as she hurled your pants across the room. "Now for the underwear!"
You started to panic as the chances of you making it out of this without your mom's dick being jammed up your ass were looking pretty slim. Regardless, you dramatically increased your struggles, so much so that you actually managed to buck your mom off you for a brief moment only for her big butt to come crashing down on your back again.
"Oh goodness! Someone is eager to have some fun."
"Mom, seriously! Get off!"
"Oh, don't worry! I'm definitely going to get off." Your mother yanked your underwear off and tossed it near your pants. "Now. Let's have some fun, Sammy."
Your mom lifted her butt off of you, and the second you were free, you darted towards the door.
"Sammy, wait!" your mom shouted.
You weren't listening. You had to get out of her before the worst comes to pass. You were almost at the exit when you felt your mom tackle you. You landed on the floor with a thud, and you felt your mom's full weight land on you and knock the air out of your lungs. You started coughing, but then your eyes went wide as you felt your mom's massive leaking cock resting between your ass crack. Your mom began grinding her hips against your ass sliding her dick up and down your asscrack.
"Sammy your butt crack feels so good. I can't wait to plow your ass."
"Mom get off! This isn't funny!"
"You're right! We ought to get right to the main event."
Your mom hocked a loogie onto her dick and began stroking it getting it nice and lubed up. After she was satisfied with the slickness, she lined her dick up with your back door and gently pressed her cock head against your forbidden entrance. You began to make one last attempt to wriggle free, but then you felt the sharp pain of your mom's massive cock sliding into your asshole.
"Holy tightness," said your mom as she relished the sensation.
You, on the other hand, were in total hell. With each successive thrust, your mom buried inch after inch inside your asshole. As it slid it, you could feel the individual pulsing veins that zigzagged across her shaft dragging across your delicate insides.
"Mom! You're too big!"
Your pleas were silenced as your mom gave a hard thrust jamming the remaining inches of her cock inside your ass. You could barely breathe. You could feel the wirey hairs of her massive bush resting against the inside of your asscrack.
"Oh, Sammy! Your butt feels heavenly! We need to make this a regular thing." Before you could protest, your mom pulled back and slammed hard against your ass. You were seeing stars as your mom picked up the pace and began pummeling your back door; the wirey hairs of her bush scratched at the inside of your asscrack; each successive thrust **** the air out of your lungs. This was a nightmare.
Suddenly, the pace of her thrusting accelerated. You could hear the unsettling, meaty sound of her hips slapping against your ass cheeks. You could feel her cock pulsating inside your asshole.
"I'm so close, Sammy. Your ass feels amazing."
You scrunched your eyes closed as you braced for the inevitable. With one last forceful thrust, your mom buried her dick balls deep inside your asshole and unleashed wave after wave of torrential viscous seed inside of your butt. Your mom grunted in satisfaction as she continued to gently grind against your ass making sure to empty every last drop of cum in your ass.
"Ah! Now that was something else," she said as she pulled her dick out of your ass with a wet SHLORP and a river of cum oozed out of your back door
