I missed the last train and ended up going to a love hotel with my best friend and his girlfriend. Seeing his girlfriend's disheveled appearance, I lost control of my rationality and started rubbing myself against her to masturbate. Then she woke up, and although I expected her to resist, she became aroused by my erect cock and whispered, "It's okay, come on." Despite my best friend being right beside us, she got hooked on my cock, and we kept repeating creampie-filled NTR sex right next to him until morning.
