Mystery Girl part 5

Somehow, I knew that I wouldn't see her for at least a couple of days, if not weeks. There was just this feeling in my guts. The next day I got out of bed and cleaned up my room a little, collecting my clothes from the floor and vacuuming the place. I brought the laundry into the kitchen only to find that the washer is broken. Putting my stuff into a basket, I called Amy. Maybe I could use her washer. She said that it was totally fine for me to come over, so I did.
She opened the door and hugged me, nearly causing me to drop the laundry. She led me through her living room and downstairs into the small basement. The stairway's ceiling was hung with her drying clothes. She loaded her washer with my clothes, oddly inspecting my jeans from yesterday a bit, before she started the washing process. We headed back upstairs and sat down on her terrace to chat by a cup of coffee.
When the laundry was due, I excused myself, telling Amy to wait while I quickly grab my stuff.
The wet clothes were quite a bit heavier than they were before, so I put the basket on my shoulder and started walking up the stairs. Not even five steps in though, I got caught in the clothes hanging from the ceiling and stumbled backwards, tearing down a bunch of clothes with me. Lucky me landed soft with my back on a pile of clothes. Amy must've heard the commotion, cause not even ten seconds later she appeared at the top of the stairs, asking if I'm alright.
I just laughed, pulling one of her slips out of my face, and gave her my thumbs up. She laughed and came down the stair. Together we hung her stuff back up and put my clothes back in the basket. She brought me to her door 'to make sure I wouldn't fall and break my neck' and we hugged goodbye. Somehow she seemed more stiff than normal today, but it might be nothing.

Later that day I went back to the park hoping to find the girl again, but nothing. I waited for hours but she never appeared. I waited a few days before heading into the park again, but still no sign of the girl. I felt humiliated and frustrated.
About a week after my last meeting with the girl, Amy knocked on my door. She was wearing her swimsuit and asked if I'd like to swim in my pool. With nothing else better to do, I agreed and we headed into my backyard. I quickly changed into my swim shorts and we both jumped into the water. By the time I was about to say I've had enough, Amy stopped me from going indoors by grabbing me by my arm. She pulled something out of the little bag she brought and handed it to me. It was a little piece of paper with an address on it. Amy said, she found it in my jeans the other day and took it, because she didn't trust the girl. But now it seemed like she was on a guilt trip. I just took the paper and thanked her, trying not to freak out internally. Amy hugged me goodbye and left. Naturally, I thought about going to that address, but it was quite late already and I was tired and soaked from swimming all day. Plus, I felt betrayed by Amy a little. I didn't know how to feel about that. Might just be my otherwise poor sex life speaking, but Amy being distrustful in the girl, maybe even jealous of her, was somehow turning me on. All of a sudden, two hot girls developed an interest in me at once.
When I went to bed, I had the weirdest dreams. Partially of me and the girl, and partially of the time Amy and the others were alone at the beach. The time Amy had this distinct stains. Somehow, that image wouldn't leave my head, until I drifted off into sleep.
