[Subjective Video] I cheated on my best friend's girlfriend COM-448

That night, I was drinking at home with my relative, his girlfriend (99cm, I-cup). Seeing her large breasts, I couldn't resist having her perform oral and breast sex on me when my relative wasn't looking, and I also teased her with a vibrator. She seemed confused but didn't resist fiercely, so I enjoyed it without worry. After a while, everyone was quite drunk, and while my relative was asleep nearby, I started massaging her breasts. She woke up and quietly resisted, but I forcefully stimulated her with the vibrator, causing her whole body to spasm and tremble uncontrollably. Afterwards, I made her perform oral and breast sex on me, then inserted my penis into her vagina. She struggled between reason, a sense of transgression, and pleasure, continuing to be manipulated by me.
