Everyone is over 18.] I looked from my laptop up as my sister Angie came into my room. Hey Zack, whats up? she said Hey sis. I just heard from Stepha...ie. She has too much work to do this weekend, and she cant make it back. Our older sister was in college and had been planning to come back for the three day weekend that now stretched out before us. That sucks. So are mom and dad at that conference? No, they are out for tonight, back in the morning. Then they leave for it tomorrow morning, and. Helen would have liked to leave them in privacy for this, but unfortunately Frank's legs were entangled with hers and she couldn't escape.Eventually the two lovers parted and Helen could go up to her room for a shower and the day went on as usual.That night Karl took Helen up to bed, to the obvious relief of Frank and Paula, though he didn't seem to notice or care what they thought about it. In his room he pressed Helen to the floor and pushed his still droopy prick in her mouth. It went in. She hold the phone to her ear with her left hand, her index finger on her right hand strokes the lace top of her hold ups and her skit is lifted.He answers the phone with his usually breezy voice, her whole body spasms, and she feels her cunt run with her juices. They chat and her fingers stroke further up the thigh, her fingers slide inside her moist knickers, her finger starts to circle her firm clit.He asks what she is doing, she tells him to guess. He's reply is you naughty girl , how wet. Now, holy crap, I’ve got to figure out how we’re going to do this. I knew that Mr Matthews was going to be fine with this, given that he was the one who told me that real men don’t beat around the bush on these things. Heck, I was a lot more worried about meeting Mr Matthews than Jen’s mom, but that all changed, and I had to worry about Mrs Matthews wanting to kill me. But I guess that Mr Matthews cleared the way for me, because when we got back to the big house, Jen just jumped in her mother’s.
