She was so hot and so tight I knew I wouldn’t be able to last long if I started thrusting into her. It didn’t help when she started rolling her hi...s beneath me, causing all sorts of sensations to shoot through me. I rubbed her back for about five minutes before I couldn’t stand it anymore. I leaned forward, laying above her, pulled my hips back, and thrust deep into her. Just the sound of my hips slapping against her ass was incredibly erotic. I was rewarded with a loud ‘YES!’ from Lori as I. .what WE did. Knowing that nothing will spare me from the cruel passing of time, I reach into the pocket and pull out my phone. The screen lights up brightly, hurting my eyes softly. The I see it. Four messages. All by 'Sabrina'. God. What the fuck did we do, honey, I ask myself. A swipe up reveals the contents of the messages:1st message: 'Dad, where are you?'2nd message: 'If you are scared, I won't tell mom or Jessica, anything!'3rd message: 'Just for my piece of mind: I don't regret it'4th. I watch my cum (yours ) flow out of the tip, a spurt shoots out, then the remaining creamy fluid flows down across my fingers and onto my shaft. I have to rest and recover in the warm water for a minute before I clean up and finish my shower. I towel off and enter the bedroom. She is still sleeping peacefully. I quickly dress, the shower was longer this morning and I am a bit behind but with a naughty smile and a very satisfied cock. The day goes by quickly, I’m sure it has to do with. It was a familiar summer vacation, but not quite long, I was bored. One day, it was a middle of our vacation, me and her returned earlier from the beach. I went to my room to have a shower, so was she. However, while I was closing her room, I noticed that she is not inside. I went down the hall that leads to bathroom and I had what to see. Bathroom door opened and straight look at my sister. She was having a shower at that time, washing her thighs and stomach, so I was lucky and have hold view.
