Lift her up and impale her
From Create Your Own Story
You think to yourself that you've waited long enough. Using your new found strength you easily lift your mother, much to her surprise, and position her pussy right above your dick. Letting go of her, she falls straight on your prick and gasps as she's speared by it. To your surprise your mother isn't the only one who becomes paralyzed, you too become unable to move as you try to get used to the stimulation.
"It's too big!"
Your mother complains as you realize that her gasp was from pain and not pleasure. Although your mother is experienced in sex it seems her pussy depth is not deep enough for your prick, meaning that when you impaled her, your prick penetrated not just her cunt but also her womb. Taking a deep breath you grab on to your mother and hold her in place to prevent her from escaping from the pain. Much to your surprise she doesn't even try, she just remains on top of you, looking at you for directions as she gets used to your size.
You both remain still for a couple minutes, only hearing each other's breathing as you both get used. Looking at your mother's chest you see her breasts slowly bounce as she breathes. "Ok, I'm going to start." Finally tired of waiting you decide that it's time to get to work. Your mother's body becomes stiff as she prepares for the pain. You slowly lift her body, giving her the much needed relief. Only to drop her again on your prick. You repeat this again and again, ignoring her grunts that slowly changed to moans. Eventually you didn't even need to lift her, your mother would just move herself up and down, impaling her cervix over and over again.
You clench your teeth as your body goes numb, your hands holding your mother down as you thrust deeper inside, unloading your seed directly in her uterus. You mother's body contracts as she spasms from her climax. Your hot seed hitting her walls was too much stimulation as she falls on you. Normally this would be bad considering the difference in size, however thanks to your new prowess you barely feel her weight.
After a couple of minutes of resting, your mother lifts her torso off you, your massive dick still inside her. You push her, this time you were going to be on top. This sudden action catches your mother off guard as her body simply concedes to your dominance. Holding her down you start to thrust, your mother's moans growing louder and louder. That was actually becoming a problem. While you had control over your mother, that wasn't the same for the rest of your family. If they caught the both of you like this, things could get nasty and fast. Looking around you find one of your used socks, picking it up you notice the stink of your sweat in it. Making a ball out of it, you shove it in your mother's mouth. An action that goes completely unnoticed by her current state. Now with her moans' volume under control you start to thrust harder until once more you cum inside her, once more the unloading is too much for your mother and she orgasms. Your mother collapses on your bed, her body losing all strength.
However you will have none of that. Turning her body while still buried, you put her in doggy style. With no strength left in her body only her rear is lifted up as you pound her cunt again and again. Eventually cumming one more time inside her causing her to climax once more. Her belly was visibly inflated from all the seed inside her. Your mother is completely lost in pleasure, drolls staining your bed sheets.
You feel tired, it seems you've reached your limit for now. Your vision grows dark as your body falls on your mother's.
