It started suddenly and subtly. Kyle entering his home and laying on his bed, stripping down as he idly scratches his chest. He had a long day, worked his office job, then got mugged on his way home. His assailant, a pudgy man who seemed overtaken with a fit of rage and lust. Kyle was stunned as he felt a muscular hand wrap around his back and pull him close, the thug pressing Kyle against his hair filled pecs.
Kyle shook his head, remember this... bizarre encounter. His body tingling as the memory continued, the thug beginning to have his fun. Kyle remembered himself being pressed against the bloke, his face forced against the man’s hairy chest. His struggles suppressed as the thug toyed with him, pressing him against his chest before grabbing Kyle's head and bringing it to his own. Kyle, seeing the face of a 30-year-old man, bald and with a well-groomed beard.
Kyle felt so strange as the memory continued, a wave of pleasure hitting him as he saw his rising member. A thought occurred, he was alone in his apartment... he can stroke himself. His hand reaches his prick as he begins to pleasure himself, his memories brought back to that thug.
Kyle remembers the thug forcing a kiss, their lips connecting as Kyle felt so strange. He was always straight, he'd never kiss a stranger let alone a guy... but that all seemed irrelevant as he kissed the thug. His body and mind lost as him and the thug were linked for what felt like an eternity. The man so sexy... his body hairy, pudgy, perfect.
Kyle closes his eyes as he began to moan, the image of the thug filling him as his body begins to alter itself. Kyle was a thin and hairless man, but that all seems to change as his chest expands. Fat being packed onto his form as Kyle's chest bloats, then defines. His pecs firm and powerful, but his stomach like a barrel. Small black hairs begin to sprout out of Kyle's chest as he continues to stroke himself, his mind still recalling the thug, remembering when the man reached a hand around Kyle and groped his ass.
Pre begins to leak from Kyle's member as he thrusts into the air, his pubes now even hairier, and his dick having grown an inch. The entire tool thickening, his hand barely holding his own member, though that struggle quickly fades. Kyle's hand becoming bigger, his arm matching the growth as it grows mightier, bulkier. His arms now as thick as tree trunks, and quickly covered in thick black hairs. Kyle can't help but grin now as his mind wanders to when the encounter turned truly intimate, the thug breaking the kiss, and lowering Kyle's head.
Kyles gaze once again returning to the thug’s hairy chest, his eyes lowering as he loses sight of his chest, instead fixating on his thick and throbbing dick. His hands desperately grabbing at the thug’s prick, his lips following as he gives in to his lust. His mouth filling with the taste of the thugs pre, then of seed. His mouth painted white as the thug pats the back of his head, encouraging Kyle as he worships the man. His hands roaming the thug’s hair filled legs and chest, as his mouth cleans the thug’s mighty dick.
Kyles legs and feet begin to enlarge, trying to catch up to his torso and arms. Within seconds, they become thick and hair filled, Kyle barely resembling his prior form. His face becoming flushed red as he feels his climax approaching, the changes reaching his head.
Kyles previously hairless chin begins to tingle, Kyle stroking his prick with one hand as the other roams his chin. His hand feeling small black hairs, then longer black hairs, then a full beard. In seconds, Kyle finds a full groomed beard covering his chin, his hand roaming the rest of his face as he feels his features define. His face becoming more rugged, his lips seeming to naturally sit in a scowl, his entire body aging. Kyles own voice and grunts deepening as his strokes are filled with more force. A manly and dominant yell filling the room as Kyle reaches his limits, his seed spraying into the air, and landing on his chest.
Kyle catches his breath, before standing from his bed. A new vigour filling him as his previous life leaves him. His job and work are no more... Kyle has been reborn as a bear, and he'll enjoy sharing this gift with others!
