22 (f4m) trying my very best not to see

Today I want to see how far I can go before I finally give in. I'm incredibly horny because I haven't had an orgasm in over a month and I need to relax. But bring a college girl with me; I have to work. What could be better than a huge dildo slowly being pushed into my pussy at my desk?

Problem: I'm easily distracted and have a weakness for kneeling. So I decide to put my work next to the bed and kneel on the floor. Then I hear my roommates coming back from the grocery store and starting to talk in the kitchen (which is on the other side of my very thin door).

I'm so horny and desperate that I can't stop myself from pushing the dildo deeper and deeper into my pussy, pushing it in and out. I'm still listening to them, face down in the pillow to muffle my moans as I'm close to exhaustion.

I wonder how much longer I can hold out. My door isn't locked, so they could come in at any moment.
