As my stepbrother walked away, I took the opportunity to indulge in some self-pleasure. I slipped my hand down my pants, feeling my arousal grow as I imagined his eyes on me. My fingers danced over my clit, sending waves of pleasure through my body. But then, I craved something more intense. I grabbed a thick dildo from my bag, imagining it was his cock filling me up. I moaned in ecstasy as I pushed it into my tight asshole, fucking myself harder and harder until I came hard. I can't wait to try it with him next time
