Secret Masturbaiton

I have many visitors and sometimes family at my house but I still need to masturbate.

I'll cruise porn throughout the day and get close to cumming but get concerned that I won't be able to clean up.

I usually like to jack it for like 45 minutes and cum on my stomach or into paper towels.  I'll then put it into a plastic bag and put it into a larger trash can in my garage.

I don't think my cum smells more than anyone else but it does have that specific smell.

Any tips on how to cum and clean up without leaving a trace?

I've thought about cumming into dry/plain condoms (condoms also smell) and then putting them into a bag and then into the garage....suggestions?
