She uses this to her advantage

"Well, if you do really mean anything, then maybe we can work something out so that I forget this ever happened."

"That would be awesome. What do you want me to do?"

"I want you to tell me why you were jacking off and who you were thinking of. Truthfully. And I want you to get me a towel to clean this shit off of me. Oh.... and I want you to hand wash all of your cum out of my clothes while I am taking a shower."

"Uh...yeah sure. That's it?"

"Well, now that you mention it I also want you to promise me one favor. Anything I want when I ask for it."

"Deal. Just please don't tell the other two."

"That's part of the deal. Keep your end and I'll keep mine. Now, answer my question."

"Okay. I was jacking off because of your ass grinding on me before you left for your run. You just looked so hot in the outfit and then you rubbed your ass on my crotch and I made the mistake of thinking about how little was between you and me. It just happened. I am so sorry."

"Well, thanks for being honest, but are you implying you have a crush on me or just that your dick was reacting to the proximity of a pussy."

"Proximity, definitely proximity." I responded in a lame attempt to cover the fact that I did have a crush on her and both of her sisters.

"Well, follow me to my room so you can take my clothes and get them washed when I change out of them and take a shower to get the rest of your cum off."

She turned around and walked up the stairs with me following her and despite the chewing out I had just received, I couldn't help but stare at her tight 19 year old ass still glad in her tight running shorts. Arriving in her bedroom, she slid her top off while walking towards the bathroom connected to her room and coincidentally joined to the guest room I was in as well. This revealed her bare back to my eyes but she continued to face away from me while she walked towards the bathroom. I was so startled that she was in the bathroom and tossing her shorts out of the bathroom door before I started to move to pick up her top. She closed the door and I finished picking up her clothes only to notice that there was no underwear that had come out. Leaving her room I went to the hall bathroom that the other two girls used and washed out her clothes. Returning to Mia's room, I hung her clothes over the back of a chair to dry out and sat on her bed to wait for her to come out of the bathroom. Not thinking much of it because of the number of times I did just this, I was very surprised when Mia came out of the bathroom completely naked with her eyes closed fixing the towel that was around her hair not even noticing that I was there.
