My sister grabbed my hand and pulled me into the bedroom. She told me to strip and to lie on the bed. I was dumbstruck until she forcefully started to... strip me. When I was naked and laying on the bed on my back with my cock pointing at the ceiling, my sister started sucking on Grace's tits. She slowly worked her way down, pulling off her panties. I was jerking off slowly watching when I froze. When Grace's panties came off she had a 6” cock. I wasn’t sure how to feel but seeing that was more of. " Yes, I see," he says. "Of course."He pauses awkwardly."So, um, I'll come by on Monday to get the new assignments?" I ask."Oh, right. Of course. Good idea. No problem... ah... Marshall. So,listen. My wife and I serve Thanksgiving dinner for any physics studentswho are unable to go home for the holiday and so naturally I thought ofyou. Do you have plans for Thanksgiving?" No, I don't have plans, thank you, Professor!" Well then. My house is on 110 Maple, just up the road. Drinks at 6,dinner's. Marjoleen & me, we keep those tasty moments in our memories. As anydoes does with memorable first times. My minds' eye still sees her in that tiny blue bikini. We write about the sexy Summer of nineteen sixty seven.My mind works out a plan to have her all for myself, when we are all on a long holiday at an aunt in Bavaria.My s!ster agrees with me that the trip to the castle 'Schloss Neuschwanzstein' will be probably very boring.She agrees that taking sunbaths and swimming in the lake, at less. Like you, I love all four of you and have been terrified I might lose you. Now that you’re here and talking with me, I feel so much better. And, by the way, you both look great! You are both so beautiful inside and out, how could I not be at least a little bit turned on by you?”“Thank you for having the courage to do all this, Cee. You’ve always been the person who gets the group to try stuff so If anyone was going to do something like this, it would have to be you. I’m so grateful to you.
