HUNTB-520 "If you keep quiet, I'll do something good for you..." My sister, who has fallen head over heels in love with our new stepfather, was seen seducing him and having sex. I saw it all...

My sister, who has fallen head over heels in love with her new stepfather, was caught having sex with him... Seeing this, I can't stay silent thinking about my mother... My sister came to my room and reached for my dick to keep me quiet, forcing a rough blowjob and seduction on me, making it impossible for me to stop getting aroused... I ended up agreeing to this devil's bargain... Even if she is family, I can't resist free sex! Who knew my sister was such a slut... Both my stepfather and I are being manipulated by her.
