Prologue: Cute Mary was just so damn cute, but just that. Cute. Trevor’s hand slid up her tummy to cup her small breast, but she delicately pulled his hand away, allowing him to continue kissing her, but hesitant to go any further. After a year of dating, Trevor was finding it difficult. He was always horny these days, just out of high school, with the whole summer break ahead, and his girlfriend was cock-blocking him aga...

Chapter 7: My Little Brother the Peeper Trevor did, in fact, think about big tits. The day at the mall, being surrounded by so many hot girls had the natural effect of giving him a raging boner. He relieved it at his computer. He consciously avoided any of the fauxcest videos, but many of the girls he focused on seemed to have dark hair and big, bouncy boobs. That was okay, though. They were just porno girls who had hot b...

Chapter 10: Mary and the Makeover When Trevor opened the door to his room, the last thing he’d expected to find was his sister, laying on his bed in a pair of purple panties and a tank top, but that is precisely what he found. He stood stock still in the doorway. “Um, hi?” he said, and Stacy looked up from her phone. “Hey Trev,” she replied, “I was waiting for you.” “Why?” he glanced over at his computer, and Stacy laughe...

An hour later, Trevor nervously sat on his bed staring at the door. His poor penis was so hard just thinking about what was about to happen. When had he become such a pervert, sitting alone with a hardon, waiting for his sister to come in and jerk him off? He told himself it was for a good cause. He was learning how to be a good lover. It wasn’t just for him. It was for him and Mary. The door opened, and Stacy let herself...

Chapter 15: I Like Girls Trevor woke up alone, nearly convinced that the previous night had all been some kind of crazy dream. The dried mess around his crotch and the discarded bottle of lube on the floor told him otherwise. Stacy was gone. He rolled over onto his stomach and fumbled for his phone on the nightstand. It was just after 9:00. His parents would be in church by now. He nearly laughed at the ridiculousness of...

Chapter 18: Couples Therapy The morning’s yoga lessons, normally relaxing, could not shake Trevor’s trepidation about what was to come. It was a curious mix of feelings, he thought, being both terrified and incredibly horny. As he went through the forms with Stacy, he marveled at how relaxed she was. Then, his sister was an admitted slut, he now knew. Having sex with a couple together was probably something she’d already...

Chapter 5: Changing Room Trevor did not see Stacy for the rest of that evening. He kept to himself, bringing his PlayStation to his room and secluding himself inside, only coming down for dinner. “Where’d your sister get off to?” his dad asked over dinner. “Dunno. Said she was going out to see friends.” he shrugged. He was so engrossed in his own thoughts and the food that he didn’t notice the look that passed between his...
