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.'
It thrilled me to hear how much my family members casually mentioned the dirty incestuous sex they liked to have together. I could certainly get used to days like today. I was equally excited by the chance to play with my present. I had always been irritated by Jamie's superior attitude, so to have him be submissive with me was a bit of a turn on. I also had to admit that he looked hot as a girl in leather and pigtails. Hot enough, in fact, that I, still in my pretty pink lingerie, felt a little jealous.
My black lace panties were already filled out by a hard erection given by my aunt's naughty strapon fucking and now I made my crossdressed cousin slide my panties aside and start licking my dick like a little slut while his father and brothers encouraged him, slapping and spanking his ass cheeks, which waved barely covered by his tiny thong and very short black leather mini-skirt.
'Come on, son, be a slut for the birthday boy,' Uncle Pete said, slapping his son's ass, encouraging him to greater lengths than he had so far managed in his not so eager cocksucking.
I could see, spilling out of the thong and dangling out from the tiny mini-skirt, Jamie's surprisingly large, thick eight inch cock. No wonder he was usually so cocky. Strangely, seeing that feminine corset and skirt and submissive attitude paired with an, as yet, limp monster dick, was an even greater turn on than if it had been a tight pussy like my sister's.
I experienced another awkward pang of jealousy at seeing that my cousin not only matched me for girly good looks but had a dick that dwarfed mine. Still, he was the one on my lead, and he was the one who's ass was about to get fucked. As I made sure to make clear as I made him turn from me and take off his thong. Just like my brother had done with me, I thrust my cock deep and hard up into my cousin's sissified ass. It felt every bit as tight and stimulating as my sister's virgin cunt had just that morning.
I was really getting into being on top this time. If my aunt could tap my ass this hard, I could certainly do the same to my cousin, slamming into his hole so our stockings rubbed hard together and my balls slapped against his, his massive dick flopping against his leather skirt.
'Mmm, Jamie, you make a good submissive slut,' I said, slapping his ass, really enjoying myself, 'I don't know why you don't do this more often.'
'Ohh,' he whimpered, 'I'll get you back for this, cousin. Just you wait.'
That made me think that perhaps I wasn't humiliating my crossdressed cousin enough just screwing him in front of the family. I called his big brother over and had him get his cock out too. Soon I had my cousin blowing his own brother while I pounded his ass, getting Rob's dick nice and hard with his painted lips like I could only imagine had happened in reverse so many times.
I could see why Rob was the one the all male family made play the girl most of the time, he had a slender feminine body with long legs and a face that I could just imagine as a woman, wide eyes with long lashes and a mouth with full soft lips. I wondered what they'd be like wrapped around a cock like his brother's were.
That got me really excited, watching the brotherly sissy suck show and imagining how it was in their house as I fucked my cousin's tight ass. Meanwhile, I felt fingers exploring my own dark hole and, soon, my aunt decided to finish what she had started by sticking her strapon up into me just as I was doing with my cousin, matching me thrust for thrust albeit dwarfing me with the size of her rubber dick.
'Oh brother, you'd better be ready for a big, dirty load in the face,' Rob gasped as he pulled his dick from his brother's lips and jerked it off until he shot a great mass of sticky spunk all over him, into his pigtailed hair, over his painted lips, dripping onto his leather corset.
