This was so naughty, as I was 19 and my sister is a year younger than me, and our daddy had to work late at the office, so his boss came over to our home to drop off our daddy's spare laptop that we needed to do our college home work. We were home alone, so of course we invited him in for a coffee, but ended up giving him a lot more than that. We had such a filthy threesome where he even fucked my little sister while she used a magic wand vibrator on herself so hard that she ended up peeing on him while his cock was inside of her. He said it would really turn him on to see us both making out, so I let my sister sit on my face while I deep tongued her pussy.
