It’s becoming more like a craving rather than a fantasy. The idea of meeting with someone, a stranger, in a park or forest and watch each other jerk off seems so hot. No strings attached, no physical touch, just pure visual bliss, making each other cum just by watching. Also talk, as in tell the other what excites you about them or the situation in itself, tell the how good they look soaking wet/throbbing hard for you.
Just being out, feeling the light breeze and having the insane hot view of a stranger getting themselves off in front of you while you do the same is intoxicatingly hot. Would you be down? I’m from Europe as a general indication. The eastern part to be more specific.
