I never really liked my step sister Elizabeth. She was extremely shallow, and she only seemed to speak to me when she wanted something - usually homework help.
When our parents moved our families in together, she ended up with the room right next to me on the 2nd floor. Think of a long hallway, where the stairs led up to a small landing. My dad's room on the left, and our rooms on the right with mine closest to the stairs. We shared a connected washroom.
I didn't realize the perks of my location until a few months down the line, when Elizabeth got more comfortable. I always left my washroom door ajar, and she'd walk into the washroom with a towel or skimpy shorts and a bra before closing my door. I think she just ignored the fact that I could see her.
And why wouldn't she? I was a nerd, essentially invisible to her at school as well, even though we shared the same classes. She didn't have a reason to pay attention when it didn't suit her. Elizabeth was a boob-a-licious cheerleader, and I was a ghoul that lived in her shadow.
And drool over those boobs I did, they were massive and seemed to defy gravity, if her skimpy clothing was any indication.
I decided to be content with my small perv sessions, and got on with my life - whacking off when I could, to the glimpses I got. There was something so taboo about it.
Things stayed this way for months, until one night I heard her talking to someone. At first I thought it was my step-mom, then a friend on the phone, but after a few minutes, I realized she had snuck her boyfriend into her room.
Eventually I heard the bed creak and him groan, telling her to take him deeper. I imagined her giving giving him head. I couldn't do anything except listen.
Slowly took out my dick, imagining I was sawing in and out of her velvety mouth. Her tongue grazing the tip before I forcefully shoved it in deep down her throat. Her cheerful smile dropping as she tried to keep up with my thrusts. Imagining her tears and mascara running made my dick harder if possible.
I came when I heard him groan, as gross as that sounds. I spewed what felt like gallons of cum, way more than my shitty tissue could hold. It was insanely intense, and I realized I needed more.
==============================================================
I bade my time. Around 2 weeks later, my parents decided to go on a getaway, taking time off work, leaving Thursday night, and coming back Saturday afternoon. I was left in charge as the older one, and I unfortunately "let" Elizabeth walk all over me and throw herself a late birthday party. She had turned 18 in the last month.
I made sure there was a ton of alcohol , and bought a few roofies from this kid at school. This was going to go really well or really poorly.
Elizabeth was prepped and ready by 7 for the party that was supposed to start at 10. Her top was low cut, the upper half of her breasts out for all to see, and her skirt was very very short. I was sure if she leaned over, I would've had a lovely pre-show before the main event.
It started off without a hitch, but the whole thing was much wilder than I imagined. This ended up working in my favour.
There were a ton classmates, people from other high schools and even a few college guys. Elizabeth started panicking about the mess and her friends convinced her to drink more to calm herself down. I took this opportunity to slip my magic helper in her drink.
By 12 AM, she was stumbling around and clearly out of it. I told her friends I'd take her upstairs and put her to sleep.
I stumbled her to her room and gently lay her on the bed. As much as I wanted to slowly undress her, my dick was hard the entire evening and it was starting to get sore and tired. I peeled up her short skirt, and saw she was wearing netted underwear that left little to the imagination.
I practically tore my pants off, and started rubbing my dick along her thin panties, her slit on the other side, begging for me to enter. I finally pushed them aside, and ran my raw dick across her almost invisible whole, circling her clit a few times. It eventually became too much and I slowly eased in. God she was tight. My dick was average, about 6", but her vag was squeezing it for dear life.
I was going to cum in seconds if I wasn't careful. I waited a few more minutes, and then pushed deeper in. I pulled out a bit to notice blood.
