you feel something switching in you and see in the mirror you balls growing as if compensating for the cum production. you feel it again and see your breasts grow too. you quickly need to stand wide legged as your balls push your legs out. you quickly need sit down. to try deal with it (and to attempt to relief yourself), you, a bit painfully roll onto your now beach ball sized testes sliding your dick in-between your gigantic beanbag breasts,loudly making is slosh and squirting out milk, and slide back out, your dick hardens.
you pump your dick like this for a few minutes. increasing the tempo quickly and
climax.
For minutes streams of milk were filling the condoms on your nipples and the condom on your dick was filling as quickly.
after orgasming your were surprised to find your self having a reasonable size body again though attached to three roughly 10 by 10 by 10 blobs of white fluids in condoms that somehow haven't popped. you slip the condoms off your numb body parts and knot them off.
numb in your head you wash yourself and dress yourself (still needing to put your dick between the breasts you still have) and exit the bathroom.
