In a moment she had it in her mouth and began to suck beautifully. As she touched my balls, I wanted to blow out. My sister sensed it and put her finger in my ass and I was already spraying everything into her kiss. She had something to do to swallow it, but something dripped on her tits. When I stopped cumming, she sucked it out a little more and licked my acorn to keep it clean. She told me that she hadn't tasted such a good seed yet and for my age that I was a good stallion even with equipment that even my dad didn't have. So I helped her out of the tub.
