Fucking your sister and Mother's Changes

Of course he had to fuck her he had gone this far a bit farther couldn’t hurt, besides if he were going to use this power more some experience would be needed for future fuckings. “Fuck yeah!” he stood up and pointed at the bed she caught his meaning and walked to his bed and placing her hands on it she thrusted her booty out wiggling it side by side. Your dick throbbed in response, but as you got closer you saw her butt and decided to make it a bit bigger, you snapped your fingers and you watched as her butt began to slowly swell by the time your hard dick touched it, it had grown to 60 inches across with perfect round bubble butt qualities. Now of course John’s target was lower down but he couldn’t help but stick his dick between those huge booty cheeks and rub it up and down between them.

Monica felt it, “God bro your dick is, like, soooo fucking hot!” and she began to raise and lower her butt twerking in time with his thrusting. Then she raised her butt high her toes pushing her up, “But I want in my cunt!” she said, John obliged his dick was bulging ready to ram inside and destroy his sisters tight pussy. He grabbed her butt squeezing it and using his new muscles to lift her up he aimed then thrusted in with a single powerful thrust! In one go he had sunk in all 30 inches into her pussy and straight to her womb pushing it up his cock bulging out against her skin, Monica’s eyes rolled up and she gritted her teeth drool sliding from the corner of her lips. “F-Fuck… this… is the best… fucking… dick… ever!” she groaned.

John however didn’t give her time to process it, and he began to thrust in and out pulling out 15 inches only to send it back in. If someone had been sitting in front of Monica they would’ve seen John’s huge cock head bulging in and out. Every thrust was met with a satisfying and loud slap against her big bootay that wasn’t restricted to John’s room as he would find out in a few minutes. He pounded her hard Monica gasping as she rested her upper body on the bed her eyes rolled up so far her whites showed, and her mouth open with orgasmic bliss having orgasmed several times in the time span of 10 minutes. John felt his dick start to bulge, “Get ready sis I’m gonna fill you up like a balloon!” he grunted he grabbed her waist pulling her up. He then lifted her and sat on the bed and dropped her down dick bulging out of her stomach she gave a throaty gurgle and then came the first shot a huge blast of cum that stretched her belly even further the rest came in a stream that bulged her belly up while it pooled below making her belly bigger and bigger her womb filled to ****’s. John came 20 times in the time span of a minute and twenty seconds.

By the time it was finished Monica was so bloated her belly was a complete sphere. He pulled his dick out and for a few seconds her pussy belched out at least a litre’s worth of sperm before her inner walls closed up preventing any from leaking out. John slapped her booty but Monica was knocked out from the orgasms he shrugged and pushed her away so he could get out from his bed and gently lowered her down. He then went to the door and unlocked it and came face to face with his mother, he stood there staring at his mother, who had… larger tits than he remembered. She was also slightly taller but was still shorter than John by about 7 inches, it then occurred to him that possibly changing his sister had an effect on his mom. She craned her head and saw Monica.

Her eyes went wide and she looked down at her son’s dick and her eyes went even wider. John didn’t know what to do… till his mom said, “I see she fucked you… you enjoy it?” she asked.

John felt the odd mix of relief and confusion fill him, “Y-Yeah…” she nodded.

She then leaned in to his ear, “If you really want a good time come to my room tonight.” she breathed. She then straightened turned and walked away John saw her huge booty jiggling as she walked that was somehow bigger than his sister’s massive 60 inch booty! His dick instantly got hard again… There was his aunt and he was curious to see if his changes affected her too… However there was his old crush… his next door neighbor Mrs. Hannigan, a bodacious brown haired woman with a rather rocking body and a kindly but devoted to her family personality. Long did John love her huge E-cup breasts, and big 30 inch booty, that he squeezed from her son who also happened to be an old friend of his. He wondered how far he could alter her body to be his perfect woman...
