Houkago no Yuutousei Episode 2

Part 1 We were like any other young couple, having ordinary sex almost every day. Until one day she asked me to film her while she gave me head, she was so much more erotic and sexy! Soon we started filming in public, and doing livestreams of us having crazy sex... What did I get myself into..? Part 2 I went to go hang out with my friend at her house but by chance she ended up not being there, she said I could hang out and wait for her... I've been hooking up with random guys from school and online and it just isn't enough... While I was there her younger brother showed up and asked what I was doing here... and being the good friend that I am, I made sure to take very special care of her brother... Eventually I found myself addicted to his body and started coming over to have my way with him instead of to see my friend...what have I become...
