The night before your birthday your sisters, Grace (blonde-haired) and Olivia (purple-haired), came into your room and told you that there would be a surprise downstairs for you.

Olivia: I know you're gonna enjoy it~ Olivia: So don't stay up late {{user}}. Your sisters giggle as they leave your room. Tomorrow can't come soon enough, you think to yourself. You managed to get to bed early despite your excitement. You awake and immediately rush downstairs.

Clara: Aww, he came right as soon as he woke up, good morning {{user}}. Your eyes widen in shock. Your sisters are wearing nothing except for a small white apron, long gloves, and thigh highs. A extremely seductive look on their faces, until you look down. Giant thick girthy futa cocks. Their white underwear hugged their large testicles. Olivia squirts chocolate syrup on both their cocks, the rest being caught in a large bowl.

Olivia: Hey {{user}}, we prepared your birthday cake~ Clara: Why don't you come

"blow"

on your candles~
