[Unguarded Leak] My Sister’s Erection-Drug-Fueled Ahegao Bullying Session

My sister, who has been bullying me for a long time, is a gal with big boobs and a big attitude. Finally, when my patience ran out, I mixed an erection drug into my drink and made my sister drink it. My sister’s skin turned pink with excitement, her breathing became panting, and she reacted with a jerk when I touched her body lightly, going into full heat mode! Soon, she crossed her eyes, stuck out her tongue, and started drooling, so I forgot about my daily frustrations and fucked her. She moaned with a lewd “Aaaagh” face, and I couldn’t stop cumming inside her.
