Red Alert

Although worried about getting pregnant, the pleasure gained from sexual acts made me boldly sneak into my sister's room. The next night, risking my heart pounding with high blood pressure, I pushed her thighs apart into an M-shape, then took out my cock from my pants, slipping it under the edge of her panties to reach her private parts. To prevent G8 from actually inserting into her vagina, I still controlled the glans sliding up and down brushing the groove. But frustratingly, the stimulated glans kept secreting multiple streams of prostatic fluid from the urethral opening, still wetting the entire groove. Many times, it even felt like the glans was really drilling into her vaginal cavity. Wu... orgasm came again, this time forcing myself to pull a small distance from her private parts before ejaculating, which is air ejaculation... achieving (simulated) external ejaculation, so deceiving myself that I won't get pregnant. Finally, I took out toilet paper to gently wipe her private parts... and her panties. Hmm... as I continue playing like this, each ejaculation time gradually lengthens, indirectly training endurance ability~!
