A pure, naive virgin girl named Yuki, who has never had a boyfriend in her 25 years and has no experience whatsoever, loses her virginity. With an estimated F-cup as a virgin nurse, her voluptuous, lustful body is a sight to behold. Her skin and breasts are flawless, and when her nipples are touched for the first time, she becomes so aroused that even through her panties, a wet, slippery sound comes from her pussy. She reveals her deeply horny side, even begging, "I want you to touch me more." Her intense scream of "Aaahn!" right after first penetration is a must-see.
