It took all I had but it was a fat joint and I knew it would fuck us all up. I went back about 5 minutes later and walked by my sisters room and was g...eated with a fully naked Lisa putting on her clothes. Now I must tell you that my sister was no dog. She was 5'7 and about 125lbs with d cup tits, long black hair and nipples that looked like pencil erasers. I used to hide in her closet and watch her get dressed and undress. I'm sure you know how teenage boys are at that age. We don't care who it. We had chemistry together and this was the first time I've ever physically touched her on accident. We were doing a lab and she was bending over to look into the microscope. Let's say her name was Pa and my gfs name is Mai. Pa had that nice round bubblebutt and c cup titties. Mai had a big round ass but B cup tits. During class that day she asked for me to help her with her lab since she was new to the school. When she bent over she leaned back and rubbed that ass on my thigh. I didn't think. Because of their images, they were constantly bringing home guys for my interview. I trusted my sisters and allowed them to go on most of the dates, only turning away a few who I knew had a bad reputation or just rubbed me the wrong way. I knew that they were old enough to decide what to do and to make the right decisions. Also, with our relationship being more friendly than fatherly, they told me most of what happened. From what I had heard, Abby, not surprisingly, was not a virgin, but. She was parked on the backside of the parking lot away from the stairs.When we got to her car, she fumbled around in her purse looking for her keys. I was standing slightly behind and to her side. She found her keys and triumphantly turned around to show me when all of sudden she was aggressively kissing me, with her body pressed against mine.I took the keys from her, unlocked the door and crawled across to the passenger's side. She got in behind me into the driver's seat. Without saying a.
