Masturbating while my sister-in-law gives me a blowjob

I was in the middle of some solo play when my sister-in-law came over to chat. She found me pleasuring myself and, to my surprise, she decided to join in. At first, I was taken aback, but then I let her take over and give me a deep, passionate blowjob. It was clear that she had some experience with oral pleasures, and she knew exactly how to drive me wild. As she continued to work her magic, I couldn't help but imagine what it would be like to have my other relatives, including my aunt and mother-in-law, joining in. The thought of them all pleasuring me was too much to handle, and I released my pent-up desire right then and there. The sight of my cum shooting out was enough to make me weak at the knees, and I knew that this encounter was one I wouldn't soon forget.
