Since childhood, I've been treated like a child by my beautiful older sister. Even now, she spoils me, who should have grown up and gotten a girlfriend. She talks to me as if I were a baby, saying things like "You're so cute, aren't you?" and "Good boy, good boy." As usual, my sister's pampering finally crossed a line... While licking her fluffy breasts, my erect penis was stroked, and I gradually felt my brain melting... So this is "baby sex"... "More kisses!" "Give me lots of your milk!" I'm completely taken in by my cousin's sweet, lewd words and forget about her...
