Mara found Karen's body interesting

“I’m so sorry,” John said quickly, his voice filled with guilt. “I panicked when Karen woke up and I didn’t mean for this to happen to you. I’m really sorry, Mara.” Mara, now in Karen’s mid-forties body, looked down at herself for a moment. Instead of anger, a curious expression appeared on Karen’s face. She tilted her head slightly, examining her new hands and the soft curves beneath the tank top. “It’s okay, John,” she said calmly, Karen’s voice sounding surprisingly gentle. “I’m not angry. This is actually kind of fascinating.”

Mara slowly ran her borrowed hands over her new body, feeling the fuller breasts, the wider hips, and the softer belly. “This body feels so different. The weight is strange, but interesting.” John watched her, unable to look away. The sight of Mara exploring Karen’s mature body, the way her hands moved across the chest and down the sides, sent an unexpected rush of arousal through him. He felt himself getting hard and quickly shifted his position, trying to hide it. But Mara noticed. Her eyes flicked downward and caught the obvious bulge in John’s pants. Instead of embarrassment, a small, knowing smile formed on Karen’s lips.

Mara took a slow step closer. “You’re getting turned on watching me like this aren’t you?” she said softly, Karen’s voice carrying a hint of playfulness. John’s face turned red. He opened his mouth to deny it, but no words came out. Mara didn’t seem upset at all. In fact, she looked intrigued and almost pleased. She had always liked John, and now, being in this unexpected situation, she saw a rare opportunity to get closer to her crush. She gently placed her hand on John’s arm. “It’s alright,” she said quietly. “I don’t mind. Actually, this might be a good chance for us to explore a little. Don’t you think?” John swallowed hard, his heart racing as he looked at Mara inside Karen’s body, feeling both nervous and strangely excited by her reaction.
