Jason and his sister-in-law, Lily, are relaxing together in the living room when a football game comes on TV. They both get caught up in the excitement and start making friendly bets about who will win. Lily loses a bet and has to give Jason a blowjob, which she's initially hesitant about. However, as she gets into it, her hesitation turns into desire. She starts licking and sucking his cock, and he can't help but moan in pleasure. Eventually, he reaches climax and cums in her mouth, causing her to taste his salty essence for the first time. Despite being new to this experience, she finds herself craving more of Jason's cock. Story ends with Jason leaning in close and whispering that there will be plenty more opportunities for them both.
