Yesterday my wife’s niece, Sarah, invited us to her place for a swim in their new pool. As our city is still warm this time of year, despite being in the middle of autumn, we took her up on her offer.

We arrived at about 11am and she greeted us at the door in a short white cotton summer dress, that was just the ride transparency to show her hard, dark nipples showing through.

She gave my wife a hug and kiss and she greeted me cheerfully. ‘Welcome, uncle. You are so welcome!’, as she pressed her body into mine, kissing me on my lips.

Her eyes were playful as she broke the kiss. ‘Aunty, how do you keep your hands off him? He’s clearly been working out,’ as she ran her hands over my covered chest and shoulders.

My wife looked at her niece’s body, ‘looks like you’ve been hitting the gym too. Not skipping leg day, I see.’

‘Guilty,’ Sarah gushed, grabbing the hem of her dress and twirling, showing her legs and ass in her skimpy bikini bottoms.

‘Where’s your husband, Sarah?’ I asked, still checking out her firm body, much to my wife’s amusement.

‘Oh, unfortunately he had to go to a work meeting,’ Sarah explained, not sounding upset at all. ‘You’ll have to be his stand-in and rub my sunscreen on, Uncle. Are you ‘up’ to the challenge?’ She teased, putting an emphasis on ‘up’ as she rubbed her hip on my groin and growing manhood. ‘Ooh, aunty, we have to share your husband today. Is that cool?’

‘Very cool,’ my wife winked, knowing how much I lusted for her niece, and how much I wanted to make her cum.

Sarah directed us to the pool area and told us to get relaxed and jump in if we were ready. My wife stripped to her one-piece swimsuit and laid out on a deck chair. ‘Come here,’ she beckoned, holding up the sunscreen.

I did as expected, coating her legs as she teased me, ‘Sarah has sexy legs, doesn’t she? And such a perky spankable ass!’

‘I want to explore that tight body,’ I confided to my wife. ‘Do I have your blessing?’

‘Definitely,’ she answered. ‘She deserves a good orgasm, with her answering the door like she did. She’s probably so horny, she’ll be wanting to suck and fuck you. Are you ‘up’ to the challenge?’ She asked, mimicking Sarah’s tone.

As she asked this, she flicked the straps of her swimsuit off her shoulders, displaying her hardening nipples to the warm sun. I squirted sunscreen on her tits, enjoying how it looked like cum on her olive skin.

My wife rubbed my rock hard erection through my swim trunks, moaning as I caressed and fondled her full breasts.

‘I wanna see her pretty lips wrapped around your thick cock, baby,’ she purred sexily, as her other hand stroked her pussy between her squirming thighs, as she stroked my dick through my trunks.

‘Swimsuits aren’t optional here, uncle,’ I heard Sarah behind me, ‘swimsuits are prohibited today.’

I looked over my shoulder to see Sarah place drinks on the outside table. I gawked as she undid the top buttons of her dress before letting it fall at her feet, exposing her gorgeous young body.
