An unexpected wakeup

"Good morning birthday boy!" came a loud cry, shocking Max awake, to the site of his family standing next to his bed, grinning. He groaned.

"I told you guys I didn't want you to do anything for my birthday," he said groggily. "I think waking me up at" he looked at his clock "5:30 in the morning counts as something."

"Oh, don't be a spoilsport," said Morgan, putting her hands on her hips. "It's not everyday you turn 18. Come on and celebrate," she said, as Katie and Heather began pulling him out of bed.

Left with no other option, Max allowed himself to be dragged to the bathroom. Mention of a shower had him thinking about his triplet sisters' hot bodies, and how great they would look if they got in the shower with him, washed him with those bodies, and then gave him a birthday present of losing his virginity with all three of them. He shook his head to clear the cobwebs of sleep and random teenage fantasy, and, not turning around, began to undress once he heard the door close.

Nude, he turned to reach for the shower faucet and was shocked to see his sisters down to thier underwear, Katie already pulling down her panties.

"Don't just stand there staring," admonished Heather, "the sooner you get the shower going, the sooner we can get clean."

"Yeah," added Katie, "and don't forget what we promised you for your birthday. We're going to teach you all about fucking this morning. By the time we're done with you, you'll know how to please a lady," she said, smirking as her bra came off, leaving her completely and unashamedly nude before her brother. Her breasts were fine and perky, although not quite as large as Max had imagined. His eyes bugged out as they grew before his eyes, matching his fantasy perfectly. He looked at Morgan, just getting her panties off, and saw that she had also grown, but strangely her bra still looked to be the right size.

'Holy crap', he thought. 'What next, mom finished making breakfast and comes to join in? We'll need a bigger shower.'

Suddenly, the door opened, and Max's jaw went the rest of the way to the floor as his mom came in, and began stripping. "Alright, I finished setting up breakfast. When we're finished turning my darling son into a studmuffin, all we'll need is a couple minutes to get the food reheated," she said, quickly and efficiently ditching her clothes. Max could see her form visibly changing in advance of her cloths coming off, and by the time she joined her daughters in nudity, she was a MILF dream.

Walking past him, she reached into the suddenly much larger shower and began to adjust the water.
