Des:My cheeky but super kind sister-in-law couldnt see me struggling with my virginity, so she said, ``Its okay if you put on a rubber band, and let me have sex with her to get rid of her virginity! But I didnt know how to adjust, so I shook my hips like an idiot, and the rubber broke inside her vagina! I thought I was there the whole time, but my sister-in-law felt so good that she realized it halfway through. But as a result, I had to ejaculate continuously...I ejaculated so much that my semen overflowed! sorry! Please forgive me because Im a beginner!
