Getting off to all of these
Basic but can’t stop jerking to them
GF needs to close a sale and agrees to fuck her client (male or female)
GF goes to dinner with a client, has several drinks, and ends up in his/her room. Maybe with 2 or 3 of them
GF makes friends with a guy or guys at the gym. They watch her workout, she starts teases them, and they develop a FWB relationship
