I had spent my birthday getting sucked, fucked and dressed up by my mom, who blew my dick and fed me my cum, my dad, who gave me my first taste of cock, my kid sister Grace, who gave me her eighteen year old virgin pussy, my big sister Gail, who dressed me up in sexy girly lingerie, and my big brother Adam, who fucked my sissy ass for the first time. It had been quite a day, but it wasn't over yet, not at all. Even as I felt my brother's spunk run down my thighs over my thigh high stockings, I heard my mom tell me that all the rest of the family would be here shortly for a party and more surprising erotic treats.
Fortunately, Gail had the forethought to bring spare clothing and I was able to clean up my cumsoaked ass, cock and thighs and slip into a new pair of black lace panties and another set of thigh high nylons. Pretty soon, I looked just the pretty girl I had been before and ready for my big birthday party, where all my extended family were going to see me dolled up and slutty.
This family was my dad's brother, my Uncle Pete, and his three sons, Rob, Dave and Jamie, and my mom's sister, my Aunt Helen, her husband Uncle John, and their twin daughters Kelly and Joanne. Thus far today, it had been a pretty strange birthday, but with the whole extended family about to join in, I could sense it getting even stranger. I wondered what sort of presents they'd have in store for me.
Aunt Helen and her family arrived first. They were quite a mismatched pair, Helen was tall, long legged and busty like her sister, my mother, only with long tresses of blonde hair, a total fantasy babe even in her 40s. Her husband, however, was a timid, skinny little man with thin light hair and a wispy moustache. There was no difficulty in telling which of them was in control in their household, it was obvious just from the way Helen moved around the room. The twins, my cousins, were not as tall or as curvy as their mother, but were two cute and naughty 19 year olds, dressed in short pleated mini-skirts and thigh high stockings. Kelly had her mother's blonde hair tied into pigtails, while Joanne's was dyed in a gothic black bob.
'Happy birthday, sweetie,' Aunt Helen strode in, kissing me on each cheeks, barely seeming to register that I was dressed in high heels and lingerie.
'Cute outfit,' Kelly giggled.
'Yeah, you sexy little thing,' her sister chimed in.
Uncle John just looked nervously at the floor, as if this wild incestuous affair was not really his proper environment. I'd never have thought it was mine before the events of today.
'Now,' Aunt Helen announced loudly to the room, 'Time for a present for the birthday girlyboy.'
She reached into her bag and pulled out a massive rubber cock. It was jet black, but with a completely realistic shape of bulges, veins and contours and must have been almost eight inches in length, longer even than my dad's thick hardness. It had a strapon harness that my aunt was preparing.
I watched open mouthed as my aunt shed her thin dress and dropped it to the floor. She was wearing no bra and her beautiful breasts dangled free, hardly sagging at all for a woman of her age. She slid off her dark red panties and slipped into the strapon harness. Now she looked like a hot curvy older woman but with a cock that would put most men to shame. It certainly managed to shame the dick in my lace panties.
'Here's your present, honey,' my aunt grinned, 'Another nice, fat cock for you, only this time it's your auntie's dick!'
'Wow, Aunt Helen,' I gasped, 'It's so big.'
'Don't worry, baby, it's just the way my husband likes it,' she replied, grinning.
Over in the corner of the room, Uncle John blushed bright red. Even seeing his cocklusting nephew dressed in a babydoll and stockings, he was embarrassed to have people know he liked getting screwed with his wife's strapon.
I, however, had no such worries, not I who had loved feeling my dad shoot his cummy load down my throat, who had spread his stockinged legs to take his brother's dick inside him. No, I simply got to my knees, opened my lips and started sucking. It was real big in my pink mouth, stretching it wide open, but I loved the feel of going down on another family dick, even a fake one.
After getting her strapon nice and slippery wet, my aunt made me turn around and, for the second time that afternoon, I gave a show to a room full of my family of me spreading my legs and getting a cock up the ass. I started to feel really good as my aunt's monster strapon impaled me even deeper than my brother had. I was riding my ass up to meet my busty aunt's thrusts and all the time my own dick was getting hard once again.
Unfortunately, we were interrupted in the middle of this kinky scene by some more arrivals, this was Dad's side of the family. Uncle Pete, like my dad, tall and broad shouldered, came in followed by his three sons. Or rather, he was followed by his two eldest sons. Jamie, the youngest, who I had always found superior and a little mean spirited around me, I could not see for a moment. Then I saw that Rob, the eldest son, had something in his hand, it looked like a chain or lead.
Sure enough, on the end of the lead, attached to a choker round his neck, was the third brother, crawling on all fours. Jamie, however, looked nothing like his usual preening superior self. He had been dressed like me in lingerie, white thigh high nylons, a black lace thong, leather mini-skirt and a leather corset laced tight to give him feminine curves. His dark hair was tied in pigtails like his cousin Kelly and he was made up with dramatic slutty make up.
'Here you go, son,' my uncle said to me as my cousin crawled over the floor toward me, 'We've brought you a present, a little something to play with.'
'I'm not into this,' pouted my sissified cousin.
'But you're gonna do it and like it,' said Rob, pulling the lead forcefully, choking his brother a little, as he handed it to me.
'Rob's usually the family bitch,' Dave, the middle brother explained, 'He's quite enjoying having the day off being the submissive dolled up one.'
