it all happened way too fast . one moment they were talking , just brother and sister , the next she hugged him . tightly , closely , a little too firmly ... and he couldn't hide it any longer , how could he have ? slowly but surely his lips inched closer to hers , and as he saw the lust in his eyes reflected in the nervous dark brown saucers of his big sister's , he kissed her passionately and flushed her cheeks a delicious shade of bright pink . they kissed , moaned quietly as their tongues danced around each other , and he let out a shameless groan as his cock strained against his jeans . her hand moved . down , down , grazed his inner thigh , and stopped where he needed it to . at once , she kissed him with all the pent-up sexual energy she could release , moaned into his mouth , and squeezed hard around her little brother's aching hard-on . lightning-struck with the sudden surge of pleasure , he thrashed about as he started to cum with abandon . thick ropes of white , hot cum filled his boxers and he whimpered as his sister kissed his breath clean away , licked his lips and told him to cum just a little more for his big , beautiful sister ... it would be one of many , many lewd transgressions to come , and they savored saving up all that love , lust , finger-licking tension to let it out at the most inopportune moments , treating each other to a wholly unexpected , mind-melting cum every once in a while ... ... they behaved themselves the rest of the time , weren't they proper siblings ?
