IENF-244 - My little sister decided to help me out with a 'thigh job' but things got way too heated, leading to an accidental raw climax.

Caught red-handed masturbating to my sleeping sister who was showing everything. Instead of getting mad, she felt pity and offered a 'thigh job' with a strict rule: no penetration. But the tension was too high, and one thing led to another—we ended up going all the way.
