German: Lucky catch after my birthday party
Posted: 03 Nov 2025 09:43
After usually having no luck when it comes to getting any interesting audio material during my business trips, I got lucky this time — maybe I just had a good instinct.
Two weeks ago, I celebrated my birthday as usual with family and friends. My sister-in-law, who recently separated from her husband, and one of my old college friends, Chris, stayed overnight at our place.
They’ve known each other for several years from previous birthday parties and have always gotten along very well. Since her children are now old enough to sleep in one room with her cousins, I set up the sofa bed in my office for my sister-in-law. My old college friend was supposed to sleep in the guest room in the basement.
As the evening — and the party — went on, my wife and I noticed that the two of them were chatting lively as always, and there was some subtle flirting going on. Later that night, after most guests had left, their conversation became more personal, and I sensed an opportunity. Because I have several test phones for work purposes (sofware engineer), I started an audio recording on one of the iPhones, which continued until our guests left the next morning.
That night, when my wife and I went to bed, I tried to listen in for a bit during the walls, but I was quite drunk and didn’t hear anything else. So I assumed the recording wouldn’t reveal anything interesting. Listening to it later, however, proved me wrong.
Roughly 20–30 minutes after my sister-in-law went to bed, my college friend quietly knocking on the office door and whispering something to her. She invited him in, and they talked for another half hour or so. At that point, I still thought nothing more would happen. But then, surprisingly, my sister-in-law, who is normally shy and reserved, took the initiative, and things became more intimate when she said: "Sorry for being that offensive. But I want to ride your cock from the minute you entered the house todays evening". You can hear them turning on some music (to glid her sounds?) afterward — I’ve uploaded the following minutes here, after removing all private conversation!
Have fun with Chris and my Sister-in-law. I do especially love how she tries to stay quiet during the whole session.
If you need some more contextual information, feel free to ask.
