HUNTB-691 "I... I'm about to cum, so I'm too embarrassed to have sex." My stepsister who is extremely sensitive all over her body and feels pleasure just from being slightly touched! Let's cooperate to improve her condition...

I was consulted by my stepsister, who said, 'I... I'll come too quickly and it's embarrassing so I can't do it.' Apparently, she has a complex where her entire body is an extremely sensitive erogenous zone. On top of that, she asked me to help improve her constitution, so I started touching her body... But when I actually did, she came more than I imagined! It was nothing like improving her constitution; the atmosphere in front of my eyes was all about moaning and feeling good, making it impossible to focus on practice. In the end, it wasn't just touching; we went all the way with penetration for a full-blown constitution improvement!
