Before I was far up the stairs, but far enough to be out of view I paused for a moment to listen. Between the clinking of dishes and the sounds of run...ing water I could barely make out them whispering and giggling. I had a feeling this would be an interesting night. Inside the bathroom, I pulled my shirt over my head and unbuttoned my jeans. I let them fall to the floor and soon my boxers were in a pile on top of all the other clothes. I stood there for a moment, looking at myself in the. That's what happened to me today. I was thinking of you, and my panties got wet. I had to take them off and was 'commando' from second period on." That's so hot to hear baby," I said as I pushed my way inside my little sister. She was much more relaxed than the previous night."I love how you feel inside me. I think it hits up against the back of my vagina," she said."That's called the cervix, Stef. I could hurt you if I'm hitting your cervix. That's where my sperm goes to find an egg. It is. “Curfew is in fifteen minutes,” I said.“Nobody pays attention to that,” she replied.“Did you know I put in an RA application? And that Dean Parker is on the evaluation committee?”“You’re afraid someone would find out and you’d lose the position because of her?”“Yes.”“That stinks,” Kristin sighed, putting her head on my chest.“I’m sorry. I didn’t realize you were going to ask me to stay or I would have said something.”She laughed softly, “It’s not your fault! I didn’t know I was going to ask. She said she doesn’t feel any pain in her body but right ankle – pulled a muscle or something and some pain in her neck.I brought a pain relieving spray and when I sprayed it on her ankle, she kind of lifted her leg in shock – I think the cold feeling of the spray. I explained to her about the spray and then I again sprayed it on her ankle. After 20 seconds or so, I think she started feeling the burning sensation because of the spray and asked me not to spray that on her neck. She asked me to.
