It was a hot summer afternoon, and step-brother Jason couldn't concentrate on his schoolwork. His step-sister Sarah, just back from college, was lounging around in her tiny bikini, and he couldn't stop staring at her perfect body.
As Sarah got up to grab a drink, Jason couldn't resist any longer. He snuck up behind her and wrapped his hands around her waist, pulling her body against his. She gasped, startled at first but then giggled and playfully pushed him away.
Their banter turned flirtatious as Sarah teased Jason about his constant erection poking through his shorts. She offered to give him a handjob but under one condition - that he would make it worth her while.
Conflicted between lust and fear of getting caught, Jason agreed. He led Sarah to his room and closed the door behind them.
