My friend went to the shower, and the door was left open. The warm, humid air from the shower filled the room, mixed with the sound of running water. It was at that moment that her partner, who was there, came to kiss me, and desire exploded between us. Our bodies met, and sex began right there. The sound of our moans soon joined the sound of the water, and my friend came out of the bathroom, watching us. The surprise on her face gave way to a smile, and she joined us. That moment became a threesome, with her partner alternating between us, an explosion of pleasure that united us in a new and intense way. He fucked me and her, without distinction, surrendering to that desire that was born so suddenly.
