Couple has a threesome with the therapist

my husband and I have had no problems in bed, we fucked so much that nothing we do makes us feel more excited. So we decided to go into couple’s therapy. There, the therapist who helped us and recommended us an effective method that always applies to his patients, was to do a threesome with her. She would be the center of attention of the trio, as our sex toy to practice new things. And my husband and I wanted to try it. The trio is successful in the office, my husband licking her ass and she sucked on the tits while I masturbate. Helped me do a blowjob to my husband, I have learned new techniques. And while my husband scopava, to me, she has encouraged with caresses on my body.
