DANDY-584 "There's a reason why she quit drinking! My friend who always said 'You absolutely must use a condom!' actually has big breasts and loves creampies when she's drunk." VOL.1

A big-breasted older sister I met at a friend's house. She seems concerned about my younger self and starts being seriously nosy, asking things like 'Do you have a girlfriend?' and 'Make sure to use protection.' However, when this sister suddenly has the chance to drink alcohol... seeing her gradually losing control makes me hard. The sister, who sees my cock, gets turned on and is actually a hypocrite, saying one thing but doing another. I can't hold back any longer and go for raw insertion, cumming inside!
