Making Bears

added by Ogrebear 20 years ago BM S TG

Tom tried to pull himself over, the person behind him was not his wife! It looked vaguely like her but Anna didn’t have such a square jaw, or wide nose, or the stubble. He struggled but the being on top of him was stronger, and heavier.
“No….please” he cried
“Oh, no you’ll like this” said the deeper husky voice above him.

Big hairy hands were exploring over his back before settlerling onto his shoulders pinning him into place; whoever it was above him he was stronger than Tom, he felt totally overwhelmed. His legs were spread and he could feel that thing pressing into his ass crack, Tom started praying…..

Anna could heard Tom whispering prayers to himself, she knew this should not be happening, that she should stop, but Tom was at her mercy and she felt so strong, so horny. She rubbed her 10” cock up and down into Tom’s crack it felt so good! This is what Men had! Her body felt so strong! She lifted a hand from Tom’s back and began to push a finger into his ass crack, searching for his hole. She found it and he gave out such a whimper as she pushed in that she nearly stopped, but then he bucked and drove her finger all the way in to the knuckle. Yeah! Anna grinned to herself
“Your turn to be penetrated” she rumbled to herself and stuck a second finger in. Her hands were so much bigger and wider, black hair covered them but she dismissed it and went for a third finger. Tom screamed and then moaned under her as she thrust her hand back and forth; it only made her hornier.

Tom was totally overwhelmed at the sensations. His mind was overwhelmed. He felt a sudden loss as the fingers were suddenly removed then with one thrust his face was in the pillows, his ass was screaming in pain, he screamed his pain into the pillows, gnashing at them with his teeth.

The rush that Anna felt was like an orgasm in its own right, from head to toe she bucked as she thrust herself forward burying her cock into Tom to its root. She pulled out and did it again, and again, and again. With each thrust she drew in more breath, she felt more powerful, her muscles were burning, growing. Anna felt her ball sack drop from within her and begin to inflate with her load, and she had a big one coming!

Each thrust made Anna bigger, her shoulders widening, her back thickening up, her large breasts flattering and turning into 2 huge slabs of male pec, her hips changed shape, her butt grew thicker and square with each rough thrust. She lifted tom higher off the bed as her thighs lengthened. Toms legs were pushed further apart as she adjusted her thicker and thicker thighs. Male hormones rushed through her making her dick grow thicker, longer, harder. Dark hair grew all over her, and from the dense bush of her pubes up and over her six pack abs her treasure trail grew in dark and thick ,joining the carpet of hair growing over her pecs and shoulders. Her head hair grew longer, and thickened in volume, she grew thick sideburns that merged into a growing beard.

Tom lay helpless he could do nothing, he was screaming now in pleasure. He was slick was their sweat. He bucked back against the invader in him, his own cock exploded a massive load into the sheets, he was in a form of ecstasy he could not imagined existed!

Anna felt Tom cum below her, her own load was not far away now, her pendulous balls were churning ready to blow. Anna leaned back and thrust out her enormous furry chest, she spread her hairy arms, each bicep bigger than Tom’s head, and let out a roar that sent Tom into a second orgasm. She could feel the cum rushing down her dick, she thrust faster, her cock swelled and with a second window shaking bellow she came.

Tom’s head snapped back as he felt the first wave exploded into his ass. He came again. The hot liquid seemed to fill him from head to toe. The heat was everywhere, it felt like lava had been poured into him. He let out a scream as wave after wave of cum filled him. Anna continued to pump into him until shed empted her massive balls; she felt extremely spent but entirely satisfied, her big body was slick with sweat her, hair plastered to her. Anna pulled her softening cock from Tom’s ass with a popping sound, a little cum dribbled out, but almost all of her load seemed to be inside Tom. Staring at the puckered hole Anna sat down on the bed, the mattress sagging with her huge weight. The enormity of what had happened had not caught up with Anna, she was in post orgasm bliss. Then Tom moaned.

He felt like he was burning, every muscle and fibre seemed to be on fire. He could feel very movement of breeze past his skin. Tom moaned and rolled over on the bed. His vision was blurry but he could see someone on the bed too
“Anna?” he called.
Tom tried to move a hand toward his brow but the pain was too much, sweat was pouring off him soaking the sheets. Then it passed and a horniess overcame him. He watched his dick inflate at super speed, it grew past it’s normal 7” and just GREW, the mushroom head falling and slapping him in the chest, Tom giggled as it swelled thicker than his forearm. He remembered the other person, he looked up at the figure
“I need a hand with this” he said thickly. His tongue felt totally swollen. The figure moved and cool, soft lips engulfed his mammoth penis. “Yeah” he moaned.

Anna’s eyes goggled as Tom rolled over- already she could see his pecs were bigger, his shoulders rounder, and he had an enormous gut; it hung like a massive semi-soft beach ball over his hips and legs hiding Tom’s dick and most of his upper thighs. It’s thin treasure trail was growing thicker. Tom tried to raise a growing hand and Anna could only watch agog as he began his change. Then his dick appeared, slipping like a snake from under that gut and rising like a hot air balloon, growing thicker and longer with each heartbeat until it slapped against Tom’s pecs. Anna’s own dick began to grow hard again at the sight of that 14” monster. She moved across Tom’s thickening hairy, legs and took it in her mouth- she wanted Tom’s cum and wanted it now!
