Yu-waku! Nyu-yoku! ANNEX!!

 It's been 2 years since your kind and beautiful older sister
got married... One day, she returns with a bunch of luggage saying "I got a
divorce". Spending sweet time with her is like going back in time. She dotes
over me, and is the perfect combination of kindness and shy awkwardness. And
you know, big sister...I've grown up too, and when you get up close to me like
this, it's too exciting...! Later, when we go shopping at the mall, we end up
winning a pair ticket for 
an all-expenses paid hot spring trip. All alone at a hot spring with big
sister...what could happen?
