GDHH-034 My proud AV was seen by my sister, who surprisingly got aroused! By chance, I ended up watching an AV with my sister… When the erotic scene came on, she started to squirm and naturally stared at my erect dick…

My pubescent sister has recently been very interested in sex! One day, she wanted to watch the ultimate AV collection that I have, so we watched it together… As the content became more intense, my sister squirmed and her crotch tingled… Of course, since it's my AV collection, I got a full erection too!! With the perverted AV and my erect stare, my sister reached her limit! Knowing it was wrong but unable to control our excitement, we ended up having forbidden incestuous sex…
