Chapter 9: Steve Finds Out

Coming of Age Sex Story: Chapter 9: Steve Finds Out - Dating a guy exclusively can be more complicated than people might think - there's his family to deal with as well. I suppose it goes both ways but in my opinion Steve's family posed much greater challenges for me than my parents did for him. It didn't help that his younger sister was jealous I was having sex with her brother!

Everything was going along perfectly. I’d gotten a load of cum in my mouth, one in my pussy, and another yet to be determined. I’d fucked and sucked and all the while his sister had been watching without him having a clue. Now how hot is THAT!?

Steve’s dick was starting to stiffen to where he was maybe three quarters erect and growing faster by the minute. It had taken almost fifteen minutes I was guessing for any response but once it got started then it was like a snowball going downhill. Picking up momentum along the way. Another few minutes and he would be fucking me again! Mmmmmmm, I wondered what position he would want me in this time.

My room was so quiet as to be almost eerie. The only sounds were the slurping of my mouth on Steve’s dick and the occasionally moan that would escape his lips when I hit a particularly sensitive spot. I’d started to play with myself, keeping my pussy ready for the inevitable fucking I was about to enjoy.

Bang!

Steve’s head popped up from the pillow he’d be laying back on, his eyes wide open.

“What the hell was that?” he asked as he stared at the source of the sound - my bedroom door.

“Just our old house creaking,” I told him, trying to calm his fears.

“No ... someone’s out there. I swear I saw someone looking in!” he said as he sat up in bed, “Oh crap, what if your dad caught us?”

I suppose in his panic that he might think that but really, did he REALLY think my parents didn’t know what we did when I brought him up to my bedroom? Sure I never let him know about the open door but why would he think he had anything to worry about so far as having sex with me? I mean for crying out loud, they all but said, “Go fuck our daughter” when he came over!

“My dad would never spy on us,” I assured him, trying not to show that I was fibbing.

In a way it was true though as my dad never “spied” on us. Sure he might sneak a look in now and then to make sure his daughter was OK but he wasn’t like Sharon, standing out in the hall masturbating watching her friend was getting it from her sexy brother.

“Well, someone was out there so it had to be him,” he said, more accusingly this time. “I can’t believe he would watch you like that.”

My first reaction was to remind him about how his own mother had spied on us and how THAT had turned out but it didn’t seem quite appropriate under the circumstances. It’s not like my dad would ever want to join in!

“I need to go talk to him,” Steve said in a determined tone, “Don’t worry, I just want to know what the story is.”

Damn, everything had been going so well and now it was all threatening to fall apart. The last thing I wanted was for him to confront my dad in this way. I could just imagine how embarrassed my dad would be to have my boyfriend accuse him of being some sort of Peeping Tom, and to do it looking at his daughter at that!

I quickly got out of bed ahead of him and went to the door and flung it open. To be honest, I was hoping like heck nobody was there and that’s just what we saw - nothing.

“See, nobody out there ... nothing to worry about.”

Steve was upset and not about to buy my story. Amazingly his cock had lost every vestige of its previous erection which told me more than anything how bothered he was. I needed to think of something - and fast before he accused my dad of anything.

Rather than try to dream up some elaborate hoax that would only fall apart sometime later and make everything worse in the end, I went with the truth, or at least most of it.

“It wasn’t my dad Steve ... it was your sister.”
