That JAV

She works overtime and misses the last train and can't come home... and I am alone with her sister "Ai". She said to me, "Are you really working late? I was so upset because she said something meaningful to me, but she teased me by showing her boobs and seducing me. I'm lonely too, so let's do something naughty?" No, no, no, it's not a good idea to be her sister. Besides, I don't know if she's cheating on me. But this face...too cute! And these breasts...they're foul, aren't they? She stares at me at close range...and kisses me! I was caught with an erection, they took off my pants, gave me a hand job, sucked my dick, paisleyed me... I desperately fooled myself with the theory that if I didn't insert myself, it wasn't cheating on her. 'Sis, I'm cheating on you. A woman's intuition. I feel sorry for your brother...Ai will take your place..." What, are you cheating on me? Does Ai know anything about it? My head panicked, I was unwilling to do it, and Ai, who was right in front of me, tempted me and I had sex with her.
