The relationship between faculty and students of both genders is quite tolerant and permissive in our college.
So it wasn't awkward, nor scary, when my student Roger wrapped his right hand around my cock and proceeded to masturbate me in order to elicit a full erection.
Lia, his sister, who has already attended two semesters and will be my student only next semester, took off her white panties and lifted her short dress to her waist, aiming to excite me even more by showing me sex with a thin covering of golden hair so small and thin that it did not even cover and hide her delicate pussy.
My cock got so hard it felt like a steel stake stretched in the air.
Roger quickly took off his pants and, fitting his buttocks into my crotch, made my hard dick enter his ass. Soon, with skill, he managed to get my cock all the way in, all the way to the base, into his soft, velvety asshole.
His cock was also quite hard.
His sister stood in front of him and with her legs wide open, fitted her blonde pussy to his hard cock, also forcing him to enter all the way inside her.
