I technically cheated on my girlfriend with a guy. I wouldn't ordinarily cheat, I'm not that kind of person, but there's a reason I did it.

I wanted his semen. I let him fuck me with a condom, then he tied it off full of cum afterward. I took the condom and kept it in the freezer for a few days. I bought one of those squirting dildos, then the next time I used a strap-on on my girlfriend I loaded it with the cum from the condom and squirted it inside of her. The only problem with this is that after I squirted it inside her, she wanted to use it on me. So she fucked me with it and squirted what was left inside.

Neither of us use birth control because we don't technically have a need for it, being that we're in a committed relationship. I'll find out in a few days, but I may have accidentally gotten us both pregnant...
