"I like big breasts, and I use my little sister's J-cup bra as masturbation material... It's disgusting." While cursing, she made me ejaculate through breast sex with her eyes. (Miki Kanna MIDA-561)

My sister's breasts are huge, huge, huge. Mature, fresh, super-fruity J-cup. The buttons on her uniform shirt popped off. *smack* Today I'm masturbating with my sister's J-cup bra again... "Brother. That's my bra... Ha. The worst, disgusting." "I know you like big breasts, but there are limits." "Eh, do you want to use my breasts to squeeze? No, no, absolutely not." "Want my breasts?... Hmm. Anyway, it's better than you committing a sexual crime." My sister is usually tsundere, but she doesn't care if you compliment her a little, she's so cute. She's annoyed by her brother's liking for breasts, and her disdainful look is irresistible. I'm so excited. (´￢_￢) Staring... My sister who makes me ejaculate by squeezing her J-cup breasts with her eyes is the best. "Brother is a creature who can't live without my breasts." That's right. I can't live without Kanna's breasts. So today, I want to use those breasts to squeeze many times. Coming home from school, I subdue my sister's breasts. Niu Niu's cosplay breasts. Bubble breasts I see during our long-awaited bath with my brother. Moo Moo Niu Niu's cosplay breasts. Breasts in tight pajamas, about to burst. "My breasts aren't vibrators." "To insert into my sister's vagina is the worst." "But I'll die without them, so I can't help it." Kanna is best when she feels good with her brother's penis. Her breasts swaying with piston-like movements are the best. My sister who ultimately allows sex is the best. Ejaculating in her breasts and vagina is the best. Looking at her useless brother with disdain. Those eyes are the best. My sister who curses me while ultimately accepting me is the best. Kanna-chan loves it the most!
