To the gym when school gets out.

When school ended, Sarah, Katrina and Amanda headed straight to Jake's locker, where he was putting his stuff away. Since it was Friday, no one had to bring anything home with them, so they left everything in their lockers. Jake's heart dropped when he saw his step sister and hers two friends heading towards him. All three girls had these giant smiles on their faces and were rushing over, basically skipping from just how excited they were. His mind was racing as fast as his heart was, as he thought of all the horrible things his step sister and her friends could possibly make him do.

"Come on little guy! We are going to the gym! I think you need a good workout." Sarah said with a devilish smile.

"Why are we going to the gym?" Jake responded.

"You'll see small fry!" Amanda said giggling.

"Unless of course, you want those pictures and video of you naked to go viral. And If I was you, I wouldn't, not with how tiny your dick is" Katrina said, raising her voice for the last sentence.

Jake blushed and locked around, hoping no one else in the hall heard Katrina talking about his dick. Unfortunately a few girls, that were talking at a nearby locker heard and they started louldy giggling. Jake looked down and Amanda put her arm around him and started to guide him down the hallway. He was way to nervous, scared and embarrassed to resist at all, so he just went with them. As they walked Katrina smacked his ass a few times, causing him to jump each time she did it

When they reached the gym, the lead him straight down to the weight room. The gym was set up with a few basketball courts and the locker rooms on the first floor, then There was an indoor track up above the bleachers. The weight room was down in the basement of the gym and it was a very large and had a lot of equipment. There was only one way to get to the workout room and the door was on the far side of the gym, away from the locker rooms and stairs to the track. Jake was starting to get very nervous, feeling like he was basically trapped, once they got down there

"Strip naked for us. Don't worry there are no sports that have practice today, so no one else will be coming down here." Sarah said.

Jake knew he didn't have a choice, so he took a deep breath and reached down and took his shoes off. Next he slowly took his socks off and his face started to turn Red again, making the girls laugh. When he grabbed the helm of his shirt, he started to shake a little bit, but he still took his shirt off. Now it was the moment of truth and he reached for the waistband of pants and boxers, with his hands really starting to shake. The girls were already dying laughing, but the all almost fell over when he finally pulled his pants and boxers down, exposing his little soft dick.

When Jake put his clothes all together, Katrina said "let's go to the treadmills first. That seems like a good place to start little dick's workout."

As they started to walk over to the treadmill on the far side of the room, Sarah said "oh no I almost forgot something. I'll be right back. Don't worry Jakey boy, Katrina and Amanda will keep a good eye on you."

Jakes heart dropped, as his step sister turned to walk away, leaving him with her two very good friends, both of whom were very attractive. As Sarah walked way, she scooped up her step brothers clothes, making sure he didn't see her take them. She quickly rushed up to the girls locker room and tossed Jake's clothes into a random locker. Then she snuck into the gym teachers office and grabbed one of the extra locks. Sarah put the lock on the locker she put the clothes in and locked it, then grabbed a jump rope and sat down, figuring it would be a good idea to leave her step brother alone with her friends for a little longer.

The second Sarah was out of sight, Amanda put her hand on his right shoulder and Katrina put hers on his left. Amanda was a tall blonde, with a very beautiful face and an hourglass figure, who was dressed in a thin sun dress. Katrina was a shorter red head, with perky tits and a really nice ass, who was in a small crop top and yoga pants. Jake could feel his stomach completely fill with butterflies, since he secretly had crushes on both of them. His heart really started to race and he could feel his body start to tingle, making his feel even more naked then he already did.

The three continued to walk over towards the treadmills, that was about 100 yards away from the stairs. When they got there, both girls took their hands off Jake when they got there and took a few steps away, standing in front of him. Katrina turned around and bent down, sticking her ass out, as she adjust her shoe. She wiggled her ass around, causing it to jiggle around in her tight yoga pants, not even actually fixing her shoe. Jake was way too distracted watching her ass to notice and as his body continued to tingle, it got a lot stronger between his legs.

Not that he noticed right away but his tiny dick quickly grew fully hard, still only getting to two inches. Katrina slowly stood up and turned around, snapping Jake out of his daydream and causing him to look away. Amanda started to laugh her ass off, witch made Jake look down and he saw that he had a boner. As Katrina saw his rock hard little dick too she just started laughing her ass off and she wiggles her pinky at him. he felt like time had come to a stand still and he froze up, unable to move or even think straight, as the embarrassment overwhelmed him.

"You like looking at my ass baby dick!" Katrina said.

"Maybe we should make him tell us witch one of us he thinks has a better ass." Amanda said giggling.

Jake turned the brightest shade of red that either of the two girls had ever seen in their life. Of course his reaction told them that it would be an easy way to make him squirm and they liked that idea. Both of them then turned around, facing away from him and started to shake their asses. Amanda bent over basically right after she started to dance, while Katrina stood up for a little bit. Of course Jake's eyes were glued to Katrina, since he could see her asses shape a lot better in her yoga pants.

"This isn't fair, your ass stands out so much more In Those pants!" Katrina said.

"Let's shake our bare asses then." Amanda responded.

The two girls looked back at Jake and since his jaw had dropped, they both smiled and winked at each other. Amanda flipped her sundress up and she dropped her panties to the floor and stepped out of them. Katrina pulled down her yoga pants and her thong down, then she stepped out of them completely. Jake's eyes basically popped out of his head, as they both bent over and showed him their bare asses. His little dick was starting to throb around and he started to breathe really hard, having never seen a girls ass nude before.

Katrina had a fat and round ass, that looked so soft and squishy, while Amanda's ass was tight, but still very rough and looked just as soft. Jake was drooling as he stood there, not sure what he should do, but was incapable of looking away. Both of them started to shake their asses at the same time and he couldn't help but let out a loud mhhhh. The girls started to giggle and Amanda reached her hand back and smacked her ass, before putting her panties back on and fixing her dress. Katrina did the same thing, before she reached over and grabbed her thong and pants, quickly putting them back on.

"So who's ass is better nakey boy Jakey body?" Katrina asked.

"Oh look at him, he loved both of them too much to decide." Amanda answered.

"Think he could answer about our boobs?" Amanda quickly added.

"Let's find out!" Katrina said then she winked at Jake.

Katrina then quickly removed her crop top and bra, exposing her decent sized, but really perky and round boobs to Jake. while Amanda took the shoulder strap on her dress and undid then and flipped her dress down below her braless chest. Her c-cup boobs were bigger than Katrina's, but we're just as perky and round. Jake started too drool, as he stood there looking at the girls, with this goofy and pathetic look on his face. The two girls put their hands under their boobs and they started to shake them around, making it so Jake could hardly stand up.

That's when they heard Sarah coming back down the stairs and Amanda and Katrina quickly re-dressed. Jake just stood there dumbfounded, not able to think about anything but the sexy display his step sisters friends just gave him. His dick was still rock hard and throbbing, witch made Sarah start to laugh her ass off. That's when Jake's face turned that extremely bright shade of red again and he snapped out of his daydream. He wanted to cover himself, but he knew his step sister and her friends wouldn't let him.

"Let's get started shrimpy!" Sarah said with an evil smile.
