I spit her tit out of my mouth and leaned back to look at her. Our eyes met for a second before drifting to her saliva covered breast."Why did you sto...?" she asked."Does your mom know what we're doing?"Sally shrugged and said, "Of course." How about your dad? Does he know?" I couldn't picture Mr. McCall condoning his seventeen year old daughter having sex with a sixteen year old boy for three hours on a Saturday afternoon."No! And don't you even let on that we've been fucking when we go. It felt so filthy, looking outside, seeing it get dark and wondering who might disturb us. They could watch for all I cared it would be a hell of a show. His cock lined up with my pussy lips, coated with wetness, and he pushed into me. He was trying to hold back I could tell, so I whispered in his ear to Fuck me… fuck me deep. He rammed my hole for all it was worth, still holding onto my ass, gripping it tight as my cunt gripped his cock. He began to pound my pussy hard and fast as I shook. "Oh yes." I said softly.He pushed forward more, slipping a few more inches into me.He released the hold he had on his cock and placed his hands on my hips and eased forward slowly in one long push."Oh my god, you are so big." I said.He continued to slide in until he felt resistance. he was almost completely in me when I felt the tip of his cock press against my cervix. He waited, I was completely relaxed, he had slipped easily into me with my wetness. He pulled out a few inches and slowly. He said that after a long talk with is lovely wife they decided to bring another man into their bed. At that remark Joan came out to introduce herself, She was a middle aged lady, about 5'6" tall not fat but very pleasingly rounded muffin top, Strawberry blond hair (at both ends). She was dressed in a nighty that was almost transparent, Her tit (I found out later) were 36D with some nice nipples protruding from the silky fabric, After the pleasantry introductions and 30 min of getting to know.
