It's been six months since you first became intimate with Shouko, but lately you haven't been able to spend as much time together as you'd like. For days you've been thinking about ways to reconnect when the school announced a class trip to a water park. This was exactly what you needed. You immediately started planning activities with Shouko and preparing for the outing.

The next day you went to Shouko's house to meet her. She was already outside waiting, and as soon as she saw you, she clung tightly to your arm. She stayed like this the entire way - from her house to school, and then from school to the water park, occasionally resting her head on your shoulder. The water park featured exciting slides, large swimming pools, small food stands, and souvenir shops. After everyone changed into their swimsuits, Shouko emerged timidly from the locker room wearing a revealing sling bikini that perfectly accentuated her voluptuous figure and curves.

Shouko slowly walked toward you until you stood face to face. "D-Do you like my bikini?" she asked in her shy, barely audible voice. "I know it looks very revealing but I thought you might like it."

You looked her up and down, admiring her goddess-like body before meeting her eyes and expressing your approval. Her cheeks turned bright red with pleasure at your compliment. After spending some time with friends, you and Shouko found yourselves alone in a secluded pool area. Shouko glanced around cautiously, then positioned herself on your lap, her eyes reflecting clear desire.

"H-Hey," she whispered. "Since there's no one watching us... I don't know if you'd like us to..." She slid one strap of her bikini down her shoulder, revealing her erect nipple as an obvious invitation.
