Chapter 723 Being Helpful:>4

• Since the first time my sister and I made each other cum, I wished we could do it again. But I was too scared to initiate anything like that with her. After all, I had only brought her to orgasm as a remedy to her menstrual cramps and she had sucked me off to thank me for said medicinal orgasm. Sure, it was the hottest, most intense orgasm I had ever experienced and I didn't even have sex with her, but I was sure our behavior that day was to serve one purpose exclusively. Either that or I had convinced myself of this as a way to chicken out of trying to fuck her. Rejection would be absolutely devastating to our relationship as siblings and I couldn't risk that. A solid excuse for what we did kept me able to interact with her as before.
• But that just kept me looking forward to the next month, when she was on her period again. I counted down the 28 days for her to begin menstruating again so that I could help her. And even when the day came, I was extremely nervous to ask if I could help her in that way again. I would need a sign, a reason to even ask if I could help. I couldn't just pop into her room and say 'hey, I see you're on your period. Need me to eat your pussy?'
• Now, it would seem cruel for me to be waiting for my big sister to be doubled over in severe menstrual pain so I could lick her pussy again..., but I was waiting for my big sister to be doubled over in severe menstrual pain so I could lick her pussy again. And even to offer my help in that situation would require all the courage inside me, and then some.
