My cute childhood friend with big boobs seems to have someone she likes lately, making me feel a bit complicated... One day, she came to consult me about a problem that only I could help her with: 'I heard that having big boobs makes you less sensitive, so I'm getting anxious... Hey, can you touch them for a moment?' 」And then, they suddenly said something outrageous! Is this my chance? No, my childhood friend is seriously confiding in me about their troubles. There's no choice but to go for it!」 I thought and started groping her huge breasts, but the reaction was subtle. 「I guess it's really true...」 My childhood friend looked dejected. But right after that! By chance, my finger touched her nipple and she reacted with a jerk! "T-that spot... might be really sensitive..." So, every day we do "nipple scratching," developing her nipples. Her sensitivity increases daily, causing her to climax repeatedly. Watching my childhood friend like this makes my sex drive rise higher each day! What's going to happen to us!?
