I knew I should drag my ass to the Chemical Engineering lab before I had to pull another all-nighter, but right then I needed some serious “me time.” After last night, I’d earned it.
Thinking about the marathon fuck-fest with Rita last night made my dick tingle like it was still auditioning for an encore. I rubbed it lazily through my pajama bottoms and let the highlight reel play in my head — until my brain, the traitor, kept drifting back to my sister, Liza.
I’d always been painfully shy. When I got invited to my first boy/girl party — the kind with spin-the-bottle and other socially sanctioned make-out roulette — I panicked. I confessed to Liza that I was terrified; I didn’t know how to kiss. Ever the protective big sister, she immediately offered to tutor me.
We parked ourselves on the sofa, and she gave me a masterclass: soft kisses, deep kisses, tongue techniques, the works. I went to the party feeling like a pro and still struck out with every single girl. When I slunk home defeated, Liza pulled me back onto the sofa, and we smooched for a solid hour. I ended up with a painful, throbbing erection and blue balls so bad they felt like they’d been kicked by a mule. Relief only came later in my room when I wanked furiously, painting my bedsheets like a Jackson Pollock of shame.
