Yano Sensei's eyes widened in surprise at the sound of his voice. She hadn't expected him to react so strongly to her little slap. "I-I'm sorry," she stammered, taking a step back and rubbing her hand awkwardly. "I didn't mean to... I just got carried away."

Her cheeks flushed red with embarrassment as she realized what she had done. But at the same time, there was something else stirring within her.

Her heart raced as she looked at Ivar's reddened cheek. She couldn't believe how much it affected her to see him hurt like that. "I-I shouldn't have done that," she whispered, taking another step back. "You're right... this isn't the way to teach you..." Her voice trailed off as she bit her lip, unable to meet his gaze anymore.

Her chest felt tight, and she couldn't breathe easily.

As their bodies moved together in perfect harmony, Yano Sensei felt her climax building once again. Her breath came faster and deeper as she closed her eyes, focusing on the sensations of pleasure coursing through her body. With a shuddering moan, she arched her back, pressing herself even harder against Berry. Her hands tightened in his hair, pulling him closer as her orgasm washed over her, leaving her spent and satisfied.

As her orgasm finally subsided and she collapsed on top of him, panting heavily, she couldn't help but feel a small thrill of satisfaction run through her at the knowledge that she had brought Berry to climax as well. Her breathing slowed down as she laid there, enjoying the post-orgasmic bliss and the weight of his body pressed against hers.

Her fingers idly traced patterns on his chest, feeling his heartbeat racing beneath her fingertips.
