He had his right hand knuckles deep in her pussy when he felt a sudden heat in his groin followed by an intense rush of sensation. As she made his dick grow, it was like his hard-on was getting stronger and even harder. He was so overwhelmed by that he couldn't help and push his entire hand in her so hot, slick and stretchy pussy. She moaned loud then took a time to adjust, she tried to put her mouth over his glans but he had grown too big. She let out a groan of frustation before having an idea.
Before all she wanted to check something. She willed him to shrink and he did, moaning as he felt like his hard-on was getting denser. She smiled, thinking about what she was going to do. A latent fetish had come alive and she just wanted him to stretch her over and over, beyond all limits. She asked for the lube.
He gave her the bottle and she took a large dose in her mouth as she willed him even bigger than before. The lube gel quickly liquified and she swalloded some, finding the taste strange but pleasant. The liquid began to spread hitself, covering all the inside of her mouth and throat, making them tingle and flowed out over her lips. She took his huge dick and let some fluid flow over the inhumanly large glans. It spread quickly and even began to invade his piss slit. Feeling him shiver from pleasure and with a wicked smile, she let out her tongue which stretched and began to tease his slit, covering it with even more lube.
He moaned and arched his back when she pushed her tongue in his slit, going deeper and deeper. Doing so she also put her lips on his glans and pushed, stretching her lips and mouth until his dick head popped in her mouth. The stretching they both felt gave them intense pleasurable feelings but somehow they didn't come.
She pursued this incredible blowjob for a while and retreated her tongue, keeping just his head in her mouth. She made an even larger bulge along his shaft and began to deepthroat him. She placed an hand on her throat and shivered when his cock head passed there stretching her. She carressed him as she took him inch by inch until the knot she had made in his shaft bumped in her lips. She moaned, making vibrations around his so deep cock and pushed her lips, stretching thin, over the huge bulge. She was way beyond human possibilities and enjoyed avery second of it. Finaly the knot popped in her mouth and she elongated his shaft until the bulge was firmly lodged in her thoat, her hand carressing it from outside.
