I Set Her Up On Purpose

I had these shorts that were very loose on me, the head of my cock would show slightly out of the leg hole or just be visible with the large leg opening. I knew sooner or later she would come to my room asking about this or that and I was ready for her, I would turn my chair around and ask her what is up as I kept my legs open giving her a view. Her eyes went down a few words into her question, she stumbled and looked up at me then back down again. She stopped then turned around and left my room so I went back to my gaming and let it ride. Few minutes later she came back again, did the same thing and this time I was a little more excited, I could feel the chair cushion on the bottom of my cock head, knew she could easily see it peeking out. She was smiling and not able to talk, she pointed down at it then looked at me so I looked down at it and asked if she wanted to see more of it or maybe touch it. She stared for a few seconds then asked if she could touch it, the first touch of her fingers made me contract and my cock head jumped upwards and it started getting an erection pushing further out of the leg hole. She sat down right in front of the chair and had both hands up running her fingers over the head and shaft, I slid myself to the edge of the seat putting my cock within a foot of her face, pulled my short up some exposing more of me for her fingers to explore. She began caressing my balls and was just staring it everything with this little smile of wonder. The next question she asked was how much bigger does it get? and she giggled some, told her not much more, just about fully hard. Few minutes later and a few more questions, I told her she could see me cum if she wanted to but she would have to either stroke me harder or suck on it. She looked up at me wide eyed, suck on it?!?! like with my mouth? I told her yeah, she did not have to put all of it in her mouth just like this part and maybe down to here as I ran my finger over the cock head and about an inch down on my shaft. She was thinking about it and still running her fingers over it then she just leaned forward and started doing it, her lips felt amazing wrapped around the head and sucking. She was sitting with her legs crossed and just rocking forward and back sucking on me like she had done this before which just amazed me. I asked her if she wanted to swallow the cum or maybe stroke me onto her chest, suggested she take off her t-shirt for it mostly because I wanted to see her tits. I helped her get the shirt off then she went back to sucking with me promising to let her know when to stop and stroke me off. The sight of her nipples nicely erect and bouncing some as she moved around was a huge turn on for me, ejaculation was coming on so I said Okay, go ahead and stop sucking and start stroking now. Seconds later the first shot of it hit her neck and between her tits, few more followed as she let out a giggle and then leaned back in and started sucking again getting a taste of it and liking it. When she stopped she looked down at herself and laughed saying she was a little messy and was going to go shower off. She told me it was a lot of fun and wanted to do it again tomorrow, I watched her walk off out of my room and thought this is going to be a great summer break for sure.
