LULU-225 Invite my neighbor over to play and then

I'm playing games at home with my friend and his girlfriend. She is a lovely and kind girl, and I feel jealous of the close couple who seem very compatible. However, after observing her for some time, my friend treats her quite harshly. Phew... what a sinner. Moreover, he has left her to work at his part-time job. It was decided that they would be alone and seek her advice on their love issues. I respond with harmless things to avoid straining their relationship, but I can't help but worry more about the underwear I'm glancing at than the content of the advice...! I've gotten hard from those moments of looking at her underwear, so I immediately had sex with my friend's girlfriend and made her cheat!
