My girlfriend's younger sister, Hotaru-chan, loves me too much. This mischievous little sister always wants to see my reaction, so she often teases me by wearing a see-through top without a bra, making my heart race. 'You're always looking at my breasts, right? I'll keep it a secret from your girlfriend.' Hotaru-chan's display of her clothed breasts keeps my desire constantly high. 'Your dick is hard... It's okay to like me.' I can't hold back any longer, even with my girlfriend present! Hidden cheating sex!!!!!
