He used to request me to teach that subject post lectures in ...he library.We used to sit in the college library and discuss the subject. Many a times, the library used to be empty. I must admit that I never let go of the opportunity of touching his nervy and well-shaped arms and thighs, by any reason whatsoever.I always used to expect that sometime at least I would notice him getting a boner and he would. I never would've imagined that one night, my father would barge in her room and start doing things to her while she was sleeping. She was a heavy sleeper after all.
