My Stepsister on the Cell Phone and Her Boyfriend Putting It All in Me

I was standing there next to my stepsister; I couldn't take my eyes off the phone. Her boyfriend looked at me, so I went up to him and he told me that she was always glued to the phone and never gave her what he wanted. So I started giving her a blowjob while she was busy. He started fucking me hard and deep while she kept scrolling around the screen as if nothing was happening. With each thrust, I had to cover myself so I wouldn't moan too loudly. He left it all inside me, all the way in, and it came inside me without her noticing.
