Class has just ended and as your girlfriend heads out to run errands you approach your yoga teacher about spending some time after working on different poses, she's happy to help. While bending over in her tight yoga pants, you get hard. She notices so you confess that you wanted to see some naughtier poses and be alone with her, she's reluctant, but admits she thinks you're cute and loves having you in her class. She continues teasing you, this time pulling her pants down and posing in different positions so you can see her pretty pink holes. Eventually she asks your favorite position after tasting the pre cum on your dick. She decides on doggystyle, bending over so you can give her a nice deep stretch. You both have sex in various positions, her from behind and on top while talking about how much hotter she is than your current partner. Once you are both about to cum, your girlfriend walks in and catches you finishing inside your yoga teachers pussy. Worth it.
