I have a sister, her name is Hinachan. Despite her innocent appearance, she has H-cup breasts. And apparently, she's never had a boyfriend. I've secretly been in love with Hinachan for a while. When my girlfriend went on a business trip, I took advantage of the opportunity and went for her. I licked her lips, squeezed her breasts, and went deep inside her pussy, thrusting my cock until I ejaculated! As Hinachan sobbed, I told her I loved her.
