Tricks him to do a few pull ups.

Sarah walked outside to the pool area, where Jake and Samantha were sitting in the chairs at the table, with Samantha about to lit a blunt. "You girls mind if I join you?" Sarah asked "go away" Jake said, then Samantha cut Jake off to say "year sure, oh and Jake be nice to your step sister."

Sarah sat down with Jake and Samantha and they smoked the blunt and Samantha poured Sarah a mixed drink. Jake and Samantha were clearly already drunk, so Sarah drank faster to catch up to their level of drunkness. The three talked,smoked and drank for about 45 minutes. Then Sarah had a light bulb go off in her head.

"Jake you really should get back to the gym. I'm going up a lot of weight on each Machine since the last time we both went. I bet I could do more pullups then you can now." Sarah said with an evil smile.

Jake didn't notice the Conniving grin on his step sisters face, but Samantha sure did. However, instead of telling Jake that his step sister was about to prank or truck him, Samantha just sat back and giggled. Samantha and Jake have been hanging out for years and years, but Samantha didn't love how much Jake would stare at her and that he was an asshole some times. Samantha actually liked seeing Jake get a taste of his own medicine every now and then.

"No way bitch, I'll show you that you are wrong. We got a pull-up bar right there on the side of the pool house." Jake said and Sarah smiled and she said "alright, you can go first LITTLE bro." Jake walked over to the pull-up bar and jumped up, grabbing onto it. Jake started pulling himself up slowly.

Sarah let Jake do 5 pull-ups before she struck. As Jake was pulling himself up for his 6th pull-up, Sarah grabbed Jakes bathing suit. In one swift and quick motion, Sarah pulled Jakes swim trunks down to Jakes ankles, then completely off of him. Samantha bursted out laughing Hysterically as Jake turned bright red.

"Oh my gosh, Jake you have a baby dick, oh my, to think I wanted you and was just playing hard to get. Oh my God, I can't believe this that little thing is pathetic." Samantha said as Sarah ran inside with Jakes bathing suit. Sarah tossed it into Jakes room and then Sarah shut and locked the door to Jakes room.

Jake was frozen with humiliation and shamefulness. Jake just hung there, still holding on the pull-up bar. To make things worse, Jake was almost fully erect. Samantha turned to grab her phone and Jake couldn't help but watch her ass as Samantha faced away from Jake. This made Jakes dick start to twitch and he got completely hard at 2 inches.

Samantha started snapping pictures with her phone and she said "this is to funny!! Got anything to say to my Snapchat friends??" Then Sarah came back outside. Sarah started taking pictures too, then she turned to Samantha and Sarah said "what do you think we should do to him next, Samantha? I locked up his room and my mom and stepdad's room, so he can't get to any of his clothes or my step dads!"
