IPZZ-996 | After missing the last train, my girlfriend’s younger sister showed up at my place and made a provocative remark: "Want to find out who feels better—me or my sister?" — Momoa Horikita

"Whose pussy felt better—my sister's or mine??"

My girlfriend’s younger sister seems to have a thing for me, and she’s constantly trying to seduce me in a calculated, coy way. I know for a fact that this is a dangerous trap—I absolutely cannot give in!

Then, one day, she misses the last train and shows up at my place, asking to stay until the first train in the morning. She’s a little tipsy and completely defenseless. Looking at me with wide, innocent eyes, she whispers, "Don't you want to compare—whose pussy feels better, mine or my sister's?"
That one line completely shattered my self-control.
