Birthday Bumps (Part 1)

*I wrote this as a one shot but had a better idea for the second half so I decided to split it and post Part 1 now since it's a decent length.*

​

It was a Thursday evening and Martin had invited his adult children over for dinner to celebrate his son's birthday. Martin was a divorced dad in his mid 40s. His son Dan had just turned 20 and his daughters, Kayla (22)and Maddie (23).

The night had not been going very well as Dan and his sisters kept arguing over everything. Martin almost regretted even hosting the event but he rarely got to spend time with his family so he was trying to make the best of it.

Martin was cleaning up after they had dinner when Dan and his sisters started to fight again. Dan had been making fun of Maddie about her recent breakup and when Kayla tried to stick up for her Dan started teasing her about being unemployed. Both women were pissed and a screaming match ensued between the siblings. Martin ended up having to get involved and told them to grow up and stop fighting.

Martin started to make conversation with them while he cleaned up and things started to go better until Dan crumpled up his dirty napkin and tossed it into Maddie's drink. Maddie started to get mad but Kayla grabbed her arm and whispered something in her ear. A huge smile spread across Maddie's face.

"Dan, I think it's time for your birthday bumps" Kayla said with an evil grin.

"What the fuck? we're not doing birthday bumps that's stupid kids crap" Dan sneered

"You're never too old for birthday bumps Dan" Maddie winked, "Don't you remember you earned yourself some birthday bumps on your 19th birthday when you got drunk and pissed on mom's purse?"

A look of fear appeared on Dan's face.

"oh Birthday bumps that sounds like fun" Martin said, "how about you kids go in the living room and do that while I clean up in here and after that I'll bring out the cake"

The girls both got up and started pulling Dan out of his chair but Dan started to protest. Dan offered to help Martin clean up, which was uncharacteristic of him, but Martin insisted he clean the kitchen alone. He already felt bad that he couldn't have thrown a better party but money was tight. The least he could do to make sure the others enjoyed themselves was to spare them from cleaning.

The girls dragged Dan toward the living room by his arms. Dan struggled to fight them off but the two of them managed to overpower him. "No! Let go! Dad, please help!" Dan begged.

"I'm sure it will be fine Dan. Just don't drop him too hard girls." Martin said

"We won't" Kayla reassured him as they disappeared around the corner.

Martin didn't understand what the fuss was about. He remembered birthday bumps as a kid where the birthday person would lay on the ground and then two others would hold their hands and feet and lift them up so they were held in the air and then lower them, bumping their butt on the floor. The person would receive a bump for every year of their age. It all seemed pretty childish but if it occupied them for a few minutes he wouldn't mind having them out of his hair while he finished the dishes.

A short while later Martin heard Dan cry in pain. His hands were submerged in the soapy dishwater so he didn't want to leave the sink. He stood still and tried to listen.

"Uhhhhhh" Martin heard Dan moan

"Two" Kayla said

"Ugh!" Dan grunted

"Three" Kayla said

Martin thought it was weird that he couldn't hear any thuds as Dan landed but he could hear his cries as they counted. A grown man being bumped on the ground by his sisters should probably be louder...

"Ow"

"Four, do one more Maddie and then it's my turn"

Turn? Martin wondered. Weren't they both lifting him together?

Martin heard a light slapping sound and then Dan made a high pitched yelping sound.

Martin pulled his hands out of the sink and quietly dried off his hands. He crept around the corner to peer into the living room.

Dan was lying face up on the floor and Maddie was sitting on him, facing away from Martin. Kayla was standing between his legs. "and now it's my turn" she said. She stepped forward and kicked her foot in between Dan's legs. Dan yelped and his legs twitched in pain. Kayla was holding her phone in her hand, filming the whole thing.

Martin was shocked at what he saw. He was into ballbusting and was awe struck by the wild scene that was unfolding right in front of him in his own home. He watched, mesmerized as Kayla kicked her brother another three times while she taunted him. Dan's cries getting more and more anguished.

Martin locked eyes with Dan as Kayla kicked him again. Dan sobbed as he stared at Martin with a look of pain and betrayal on his face. "Dad, help me! why are you just standing there?"

The girls looked over at Martin.

Martin suddenly remembered where he was and who he was with and was embarrassed to have been caught watching what had been happening. "Yeah, hey girls you need to cut that out" he said, walking towards them. "Come on Maddie get off of your brother." he said holding out his hand to her.

Maddie looked up at Martin's hand and then noticed the boner in his pants. "Oh my god Dad, what the fuck?!" she shrieked, pointing at his crotch.

Dan and Kayla both looked at the tent that had formed in Martin's pants. Kayla pointed the camera at Martin's crotch. Martin grabbed the phone from her and turned the camera off and deleted the video and handed the phone back.

"Are you sure you want us to stop Dad? because it looks like you're enjoying the show" Kayla said as she kicked Dan in the balls again. "that's 11, only 9 more to go!"

"Ow, Dad make her stop!" Dan cried.

"Come on Kayla, leave him alone, he's had enough." Martin said, stepping toward her and trying to guide her away from her brother.

Kayla snapped her foot up between Martin's legs and he fell to the ground in agony.

"Sorry Dad but I need you to stay out of my way. Maddie, stand over here and keep an eye on him and if he moves, kick him in the balls again. We need to prove that Dan received all of his birthday bumps and since Dad deleted the video, now we need to start over."

"Nooooo!" Dan screamed.
