I happened to meet a close-knit mother and daughter. But the mother's voluptuous body made me instantly erect… I tried desperately to hide it, but the daughter caught me! Noticing her daughter's distress, the mother distracted her, saying, "Don't look!", but she couldn't help but get aroused by my fully erect penis, which she hadn't seen in a long time… While the daughter was out of sight, she said, "It's my fault, isn't it?", and proceeded to give me a blowjob! I was getting excited thinking this was definitely going to be an adult relationship, when the daughter returned and caught us! As the mother and I hastily tried to cover it up, the daughter, with a mischievous smile, said, "Hmm, isn't it unfair that only Mom gets to have fun?", which surprised me! "I'll keep it a secret from Daddy, so let me join in!", she said, inviting me to an unexpected mother-daughter threesome! With the mother desperate to keep it a secret from her husband and the mischievous daughter on the offensive, I couldn't stop getting erect and ejaculating!!
