"If it's just licking the glans, it doesn't count as cheating, right?" His sister sucked and licked his swollen glans, giving him oral and vaginal sex. He was tormented by her teasing to the point of near ejaculation, finally succumbing to her relentless torment and unfaithfully penetrating her vagina, ejaculating inside her.

My girlfriend's older sister, Shiori, came to visit. Since we live together and plan to get married, her stunning beauty made my heart race. One night, after my girlfriend fell asleep, Shiori started seducing me. "Just a lick doesn't count as cheating..." I was captivated by her sweet words and offered her my penis, but she only kissed and sucked the glans, then rubbed it against her vaginal opening, teasing me until I completely lost my mind! "Going any deeper would be cheating, you know? Do you want it all the way in?" I couldn't hold back any longer! Please, just go all the way in, let me cum!
