My wife loves teasing and this morning she was really horny and in the mood for it. Instead of indulging in her desires she went out in the backyard for a workout while I was fixing a wall in the house. She was turning me on, and I think that was her intent, wearing a tiny pair of booty shorts and a crop top. She said if she was going to the gym, she might consider underwear but as she was home she would go without. Every now and then I would watch her doing crunches, squats, dips or weights, getting hotter and sweatier and I was loving the view. She ended sitting on her yoga mat, and got out the blood pressure monitor. She strapped it on her arm and relaxed as she took a reading. Just as she did this, the noisy air pump is interrupted by a young male voice. I glance outside and see the neighbour peeking over the fence. Now, I know my wife has fantasised about him before, playing with herself while she has watched him mow the lawn shirtless and I've given her the green light if she wants to seduce him. He's saying how he thought my wife was doing something else. 'Like what, you cheeky fuck?' She asks, a smirk on her face. 'You thought I had a sex toy?' 'Uh, something like that,' he says, clearly enjoying the view of my wife. 'I'm just checking my blood pressure,' she purrs. 'Maybe yours is high now. Come over and I'll check it for you.' He clambers over the fence eagerly and sits opposite my wife. She takes the arm strap off her arm and takes his wrist and extends it towards her, resting his forearm on her knee as she straps him in. I can clearly see that he's cupping her breast, and she's doing nothing to prevent him. I'm getting harder as I watch his thumb rub on her very hard nipple and she hits the button on the unit and I can hear her murmur something. I see her other arm moving but I can't see what she's doing. She leans forward a little as if to see the screen on the monitor. 'Oh it's so high,' she coos. 'Something has your blood pumping. Look, I'll do mine again.' She unstraps his arm and makes a deal about putting it on her other arm, the one I couldn't see well. She asks him to help and he does so eagerly. He helps her and they turn the machine on again, but he rests his arm back on her knee, cupping her breast again. She exclaims when that reading comes in, 'oh look, they're both so high. We should do it on your thigh next. That's what my doctor does for me.' (I make a mental note to raise her medical appointments afterwards). She's starting to strap it on his thigh and he's adjusting to give her access and then I noticed he freezes and shudders, apologising before he jumps back over the fence. My wife sits back, her lovely tits barely covered, and she licks her fingers and then turns to where she knows I'm looking from and licks her lips, winks and says, 'I gotta shower, babe. Wanna help?'
