Well I had my overnight adventure
A drive to Niagara on the lake, a walk in a forest/photography, the hotel, wine tasting and buying, dinner, a show at the Shaw festival (Me and My Girl), drinking wine, music with her singing and me playing guitar, admiring the lake from our hotel balcony, some art, some poetry, then at 3 am she called up a friend (also an SP) for a threesome thus checking off a second item on my bucket list. The second Lady also brought more wine but not enough, and after the wine had gone, she called room service to see if she could get another bottle, but apparently that's not possible at 5 am in Canada.
The one thing we didn't do is actually "sleep" together, I passed out on the bed a bit after 6 am as the ladies were admiring the sun rise, and woke up at 9 to find the two ladies had past out on the sofa. My girl then woke up, realized it had gotten cold and scurried into bed with me for warmth.
After dropping her off at home, I messaged her later that day to thank her...
She replied, "No. Thank you. Soooo frikkin awesome."
Cost: A hell of a lot, but soooo frikkin worth it.
Romance and fun without commitment or baggage; just enjoying the company of a beautiful woman for an entire day.
