Billie

Billie giggled to themselves as they slid the key into the lock before wrapping a newly feminine hand around the handle and pushing the door inwards. As they stepped over the threshold, they parted their glossy pitch lips to call out, "Anyone in? I've got something to show you." When no one answered, she slid off her flats by the door and ascended the stairs, dragging the battered blue case behind her. On reaching the top stairs, their hazel eyes darted between their door and the other that belonged to James.

The hem of Billie's azure rubber skirt lifted at the thought of his lips around the head of her cock as she filled his mouth with her seed and initiated them as a fellow Sissiboi. Another giggle fell from their sordid lips as they slid another key into the lock and entered their former room. Once inside, they flung open the curtain, bathing the room in rays of deteriorating light as they adjusted it for their newfound needs. They no longer lust over the silicone sluts that hung from the walls; no, now, they craved the cocks of their flatmates and soon-to-be Sissiboi sisters. It was only a matter of time.

Billie smiled at herself in the mirror as she idly rubbed her hard cock in one hand whilst fondling the sensitive nipple with another. Her mind flashed back to when she had returned home to the family; Billie's usually demure mother had bumped into a former colleague at the supermarket and returned as a hulking dominant Bimgurl, quickly taking and converting her former beau into a Sissiboi. Once Billy returned from University, he met a similar fate to his former father and rose as a subservient Sissiboi eager to serve her newly domineering mother.

After they had all got reacquainted, Billie knew they had to return to University and spread the joy of SISSIES to as many of her peers as she could handle. Cum spewed from their cock and splattered against the mirror as they heard the front door open. Billie smiled at her reflection, silently mouthing Slut to herself as she headed for the door and made her descent.
