I decided to don my spectacles to get a better view of my stepsister's phallus as she was preparing for some action. But in my haste, I accidentally declined her offer for anal penetration. She was taken aback by my refusal, but I explained that I just wanted to savor the moment and take in the sight. She understood and we continued with our intimate encounter. She took my member into her mouth, giving it a thorough sucking before allowing me to penetrate her. The sensation was intense, and I could see every detail of her pleasure through my glasses. She moaned in ecstasy as I thrust deeper, her body convulsing with each thrust. Finally, I reached my climax, filling her with my hot seed. It was a sight I would never forget, and I was grateful for my decision to put on my spectacles.
