Yua-chan, a girl from Fukui Prefecture, helped our protagonist lose his virginity at her home. Without condoms. She agreed to do so after hearing that he could win 100,000 yen. Despite feeling embarrassed, she served him diligently. However, when faced with his impressively large and amazing virgin penis, she couldn't help but have a lustful expression, thinking, "I want to try inserting it...". As expected, they engaged in intense cowgirl sex, milking every last drop of cum until there was nothing left, leaving both parties satisfied and glowing with pleasure.
