My wife’s niece (f22 at the time) and I (m35 at the time) always were reasonable close and friendly.

It started when she turned 18 and became a lot more open about her sexuality. Basically no filter and her family would always tell her to shut up as the family history was very conservative and traditional.

She started exercising, toning up which boosted her confidence. She became more flirtatious and cheeky.

A few years went on and we went on a family picnic and she decided to wear a little pair of denim shorts and triangle bikini top.

We started playing football and there was a bit of tackling. Yes, she caught me looking because there was no padding in her bikini top and her nipples showed so well.

She started flirting and tackling me more and I tackled her a little bit too hard and I managed to bundle her up in my arms and turned so I hit the ground and she landed on me. We had both missed the ball and we were a short distance away from the rest of the family.

She sat up on me and I realised one of the triangles of her bikini had slipped and her left was poking out so nicely. I said to her quietly, “uh Sarah, you’ve got a malfunction happening.”

She said, “Uncle, it’s only a malfunction if it’s an accident, and besides, it feels as though you’re enjoying it.”

She ground her pelvis on my growing erection subtly and a wicked smirk on her face. The rest of the afternoon there was a lot of physical contact, with tackles and wrestling and ‘accidental’ gropes here and there. I didn’t count on my wife catching it all.

Later that night, my wife teased me about Sarah, asking if a young girl in skimpy clothes would turn a guy on. I said for sure. She asked if it turned me on and I brushed it off with, “honey, she’s your niece. She’s family.”

My wife was asking me this while she was stroking and sucking me, so she knew it was a sexual topic. Then she brought up threesomes and her watching me with another girl. She didn’t get to finish me off, but it was clear she enjoyed the topic just as much.

Later that evening, Sarah called and asked if she could come over to chill out because her mum was being overbearing about what she ate, how much she exercised and they were arguing. My wife said sure.

Sarah came over in her pjs - satin booty shorts and tank top under a short satin robe. I let her in and she hugged me a little longer, and a kiss on my neck.

My wife, Sarah and I all sat on the couch and were chatting. Sarah got really comfortable, tucking her legs up, which, from the side exposed her ass cheek a little.

My wife commended her on her fitness journey and got her to stand and turn around, smacking her ass, tell her that her booty looked great. Sarah pulled her robe up and squatted, swivelling her hips a little with a laugh, and my wife said with that move and ass she could look at exotic dancing for a living.

My wife then said she was tired and was going to go to bed, that Sarah could sleep over if she liked and I was to make her comfortable.

Sarah and I chatted a bit more and Sarah asked if I thought she could be a stripper. I said to her that my wife said exotic dancer. Sarah said with a sly wink, “what if I really like taking all of my clothes off, Uncle?”

I almost got instantly hard and she said she’s fantasised about giving lap dances to guys and she backed up between my legs, swivelling her hips and thrusting her perky ass back at me.

I took hold of her hips, and told her what she was doing was teasing. If she wanted to give a lap dance, she had to drop that sexy ass, and I pulled her down onto my lap.

She whispered back over her shoulder at me, “you’re so big and hard, Uncle.”

I lifted her off me quickly because she was going to make me cum in my pants if she kept going. She looked amused and said in a low voice, “I really turn you on, don’t I?”

I tried to change the topic and said, let’s watch some tv and without thinking, I grabbed the remote and turned the tv on, only realising as the picture came up, that the last thing my wife and I watched was a lesbian porn scene, one of my wife’s favourite scenes. I said oops, and was about to change it, but she took my hand and pulled me back onto the couch next to her, saying, “no leave it. I want to watch this.”

She lay next to me on the couch, her head on my thigh, watching the screen intently. She smiled and said she wants to try that, being sexual with a girl. I asked if she’s kissed a girl, she said yeah, kissing, groping, licking nipples. She watched and almost absent-mindedly reached into her robe and pinched her nipple.

I pulled aside her robe and told her to let me see what she’s doing, and she teased both nipples, both getting so long and hard as her breathing got heavier.

I asked what was turning her on more, watching the girls on screen, or her touching herself in front of me. She said both, and my hard cock was also making her feeling naughty.

She sighed a little, rubbed her head back so my erection was brushing against her cheek and asked if I would like to watch her and a friend do that. The porn flick showed the girls licking each others nipples. I pulled down Sarah’s tank top and her nipples flicked free. I said with those sexy nipples, definitely. I moved one of her hands away and placed it between her legs. I then started pinching and playing with her nipple. She rubbed her pussy through her shorts and smiled, telling me I was so naughty.

Sarah, being so small against me made her look so hot so I easily dragged her body up with her back over my lap, so her breasts were pointed straight up at me, and her legs were to my right. I moved her hand away and slipped my hand under her waist band. I loved that she was so smooth down there. I stroke her clit in circles and she arched her back, her nipples within reach so I sucked one into my mouth. She stayed watching the screen but gasped, “fuuuck!”

I started stroking hard, and she pushed my hand down, guiding two fingers inside her, and she started grinding her hips, whispering, “do you like how tight my cunt is, uncle? Do you like…ooooh fuck…what are you…?”

I had rubbed up on her G-spot with my fingertips, and it was clear that she hadn’t experienced that before.

I asked her if anyone had done that for her before, as the screen showed one girl going down on the other. She said no, so I wrestled her shorts off her and settled between her thighs. She asked if I liked the look of her pussy and I told her honestly, it’s a very pretty pussy and kissed her lips over and over, and she spread her thighs a bit more as she played with her nipples, pulling and pinching them.

My wife heard, came to investigate. Neither Sarah or I saw her watching in the doorway.

After I made Sarah cum a couple times, and made out with her for a while, I went to bed. My wife was awake, grabbed my cock and slowly stroked it, whispering that I had set the bar pretty high for future boyfriends. I asked how much she saw. She said she watched me take her to her first orgasm and said I needed a reward for being such a gracious host. My wife told me to imagine it was Sarah and she sucked my cock so well.

Sarah proved to be a hot topic for us for quite a while.
