Andrew had never desired another woman like he had his sister. Every time they had sex it was as passionate as there very first time. Only now, they were older and more skilled and knew how to pleasure and please each other. The kiss deepened and intensified and he felt her hands clawing at his towel until it finally gave way, leaving him naked before her. Of course, the door to their bedroom was half open and would remain so, too enamored in her to even care.<br/><br/>He grinned right back at her as she broke the kiss. "Now look what you've done..." He says, his semi-limp cock dangling neatly below. He was clean shaven down there as always, enjoying the hairlessness feel over having hair. "Now, it doesn't seem fair to me that I am naked and you are not." He says, tugging at the thin shift first, removing it by pulling it up and over her head. "Though you certainly do look sexy." He murmurs, staring at her body once more.<br/><br/><hr/><br/>Peter was thirsty so decided to head downstairs for a drink. He did so quietly - it was late at night and people might be sleeping. He filled a glass with water in the kitchen and down it in a few gulps before refilling and taking slower sips. Once he was done, he set the glass down in the sink and moved back upstairs. It was then that the light from his parents room caught his eye.  He had seen them fucking a few times already and, well, his crush on his mother meant that he jerked off while watching. He crept to their door once more and silently peeked in. Things were starting to heat up, he saw - his father naked and touching his mother.<br/>
