Was in Zurich for work a few weeks joined a dinner party at a friends house. We finished and I was heading out when his sister who’d joined for dinner offered me a ride back to my hotel. It was late and the train would have taken a bit longer so I said sure.

His sister Zoe and I had been chatting on and off and playfully flirting throughout the evening though I hadn’t thought much of it. She’s very cute - late 20s Swiss postdoctoral researcher, 5’10”, athletic build with perky little breasts and short brown curly hair. She was wearing black jeans, a white T-shirt and a green cardigan and sitting next to her in her little 2-seater BMW I couldn’t help but catch a glimpse of her nipples pushing through her top and her cute full lips smiling as we chatted.

She pulled up near my hotel and I started to thank her for the ride and get out, when I see her parking, unbuckling her seatbelt and getting out of the car. She silently walks me through the hotel lobby to the elevator and as soon as the door closes she pushes me against the door and starts kissing me fiercely. Taking the hint, I pull her in and run my hands down her toned back and grab her ass which her jeans are holding onto for dear life.

We make it into my room and I throw her onto the bed and we continue kissing as I run my hands up under her T-shirt and start caressing her tits while she’s rubbing my now extremely hard cock through my trousers. I unbutton her jeans and slide my hand down to her crotch. Her panties are already wet and I start rubbing her clit and pussy through them as we keep kissing and she starts moaning softly.

I slip her out of her jeans and underwear and move down her body, gently kissing her stomach through her T-shirt until I reach her gorgeous little pussy. She had a neatly trimmed landing strip which I kissed and bit gently before slowly sliding a finger into her as I started slowly licking and sucking on her clit. She took her top and bra off and I glanced up at her beautiful perky tits with the tiniest nipples while I concentrated on pleasuring her with my tongue.

It didn’t take long to find a rhythm of me finger fucking her and licking her clit before she was writhing in pleasure - I pushed a second finger inside her and started vigorously fucking her and hitting her gpot - she started cumming and grabbed my hair, grinding her clit against my mouth and she pushed my head down.

Thinking she’s going to need a break, I moved back up and she started kissing me again. I lay on my back and without missing a beat she swings her legs around and lowers her pussy onto my face. I obediently grab her ass and thighs, spread her pussy open and start eating her again. She slides my pants off and leans forward and starts licking the tip of my cock.

I’m in heaven with this nubile girl sitting on my face playing with my cock, and then she just swallows my whole cock in one motion- I can feel her lips on my balls. She starts bobbing up and down - it feels absolutely amazing. I start thrusting with my hips and she holds her head steady while I face fuck her with my face buried in her soaking wet snatch.

I can feel myself getting close when she comes up for air and speaks for the first time since we got out for the car “don’t cum, you need to fuck me”. “I don’t have a condom” I say while still licking her pussy. She gets up off my face, lowers her pussy on my cock, leans into kiss me and smiles saying “just fuck me”.

Again, not one to argue, we kiss deeply as I start sliding in and out of her tight little pussy. I can feel her getting wetter and I reach down to feel her wetness and start rubbing her asshole and then gently rubbing it with two fingers as she buries her tongue in my throat and I start fucking her relentlessly. She seems close to cumming again and I push two fingers gently into her asshole while I fuck her - this seems to send her over the edge and I feel her pussy spasming on my cock as I fuck her through her orgasm which seems to last forever.

She breathlessly collapses in a heap on me and is helplessly kissing my cheek and neck while I slowly keep sliding my cock into her. I gently stroke her beautiful toned back and ass while we kiss, still intertwined. She softly whispers “cum in me”. I give her a slightly hesitant look and she laughs saying “don’t worry, I’m horny, not an idiot - I’m on the pill”. Really not the conversation I was expecting to have with my friends sister a few hours earlier.

Suddenly emboldened, I lift her up, and bring her breasts up to my mouth and start kissing them, gently sucking each nipple in turn as I start fucking her harder and deeper again. She’s clearly enjoying this as she pushes more of breast into my mouth and I start sucking her tit hard and grabbing the other one, as I reaching around with my other had and fingering her asshole again while I’m fucking her. The sensations are almost too much for me as I start to fuck her harder and deeper, and when I’m close I push almost my entire middle finger into her ass and she gasps, clenching down on it while I start cumming hard in her with my mouth filled with and sucking hard on one of her perfect little tits.

She gently rolls off me and snuggles up next to me while she reaches down and starts rubbing her clit furiously. I’m still in a bit of a daze, but I turn to kiss her and rub her tits, pinching her nipples hard and she gets herself off again rubbing herself with my cum.

We both lay their exhausted and content for a while listening to the sounds of the city at night. I realise I’d practically give her a hickey on her left breast which we both laughed about. We chatted as she got dressed and she gave me a warm kiss and a hug before heading off. Totally not the end to the evening I was expecting and I’ll definitely drop her a line next time I’m in town.
