A sea of nodding heads and a forest of rising thumbs replied in the affirmative.“Excellent class! Practice makes perfect; let’s do one more review... We don’t want another Colfax cluster-fuck.” Sheila changed her voice from slightly alto to a nasal falsetto as she mimicked a grade-school teacher from Hell.The Colfax Avenue Debacle, as I found out later, was a legendary fuck-up of epic proportions. Several years after the founding of the colony, a “secret” resupply mission landed on the front. She was really looking forward to the "time together" part. She and Tim had discussed everything that had occurred on the first day that they had switched mates and enjoyed fucks with Tim's parents. This time Cindy thought it would be very arousing and very sexy if the four of them could enjoy fucks together in the same room. She wanted them to see if Chuck and Sue were also agreeable to something like that.That night when Chuck and Sue arrived at Tim and Cindy's house, they came on in as they. A deep passionate kiss. She had fallen in love with him; completely and utterly.He had taken her home shortly after, and had walked her to the door. She saw her father looking through the curtains. He said "Do you have plans for this Friday?"She had replied "Yes" Oh, what are you doing?" I'm going out with a very handsome and kind gentleman"He had smiled and with a dart of the eyes to the curtains which only she noticed, he took her hand and bent to kiss it.She smiled as he bade her goodnight,. She placed her cunt on my dick, got hold of my dick, and asked me to push it in. I did. She pressed down on my dick. And in it went. Now it was her turn to fuck me, and fuck me she did. She kept jumping up and down as I played with her tiny guavas (read breasts). She came down on me and started kissing me all over, my face, my cheeks, she was a tigress enjoying her prey. I was enjoying it too from beneath. I kept thrusting my pelvis up to push my dick in into her cunt, and she came down roaring.
