SNIS-978 My girlfriend's slutty little sister

If your girlfriend's sister is more beautiful than her, has a big chest, loves me, and always tempts me with her breasts, can you handle it? This work is the story of a man who cannot endure it. When I wake up, when I take a shower, when my girlfriend goes to work, I always snicker and ask, 'Do you want to have sex?' Just see if you surrender to temptation and if you're happy.
