A teacher

As the last client is leaving you hear Stephany ask Ellen how she did that thing with the thighs between each others legs.

A few minutes later you return with the next customer. A teacher you knew from school Mr Robertson.

When you brought him in the room you found both girls on the bed fucking each others thighs with their pussies.

Mr Robertson quickly decided he wanted both girls at once.

He refused to let you stay in the room. When you said it was for safety reasons he pointed out there was two girls in the room with him and he was a teacher.

Both bedrooms had second doors that lead in to the bathroom.

You went in to the bathroom and sat on the toilet with your knickers on the floor.

You listened to the threesome in the next room trying to imagine what was happening as you heard all the moans and squeals as well as the instructions Mr Robertson was giving the girls. While you fingered your clit to orgasm.

"Ellen suck my cock. Stephany go down on Ellen. Ellen get on top with my cock in your pussy. Stephany sit on my face. Swap around. Oh god I'm cumming."

You quickly got out of the bathroom just before he entered it.

You started swearing wishing you had got all the spare towels before he had entered.

A few minutes later he was dressed and ready to leave and you didn't get to see his cock once.
