DANDYA-045 · I Went to a Public Bath with My Mother and Was Secretly Toyed with by a Big Sister Who Chased Me Even When I Tried to Escape, Making Me Cum and Swallow My Semen Many Times

I came to a day-trip hot spring with my mom. She told me, "You're just a kid, so it's fine," and let me enter the women's bath. My mom left me behind as I felt too embarrassed to undress.
A beautiful older sister next to me spoke to me, saying, "Are you here with your mom? How cute," and I hurriedly got into the bath out of embarrassment.
As if chasing me... the older sister started washing herself right next to me, making sure to show off her big tits.
Being at that age, I couldn't help but look, and when our eyes met, she asked, "Could you wash me?" and started pressing her tits against me to tease me.
I got into the bathtub to hide my growing cock, but the older sister followed me and secretly gave me a handjob and blowjob inside the tub, making sure my mom couldn't see! After swallowing my cum, she said, "You're so energetic. I wonder how many times you can cum?" She chased me around and we had sex in places where my mom couldn't see... and she drank my cum over and over again.
