Time for you two to be spontaneous. Then mommy will never know.

That is actually really creepy. Most parents would be thankful their son was planning times for that stuff so they dont have to hear it, but OP's mum seems like she wouldnt mind walking in on them. I think your mums a bit socially retarded OP. Try discussing those matters on facebook instead, solved.

I reckon.. "Oh hey you two, hows it going in there? :D Can i get you anything? Condoms, Redbull.... a camera perhaps? No? Okay then, i'll just be in the next room! Let me know if you erm, need a hand!"

Chastity mother :/

How old are you that mommy still reads your text messages?

Sounds like your mom needs to get laid too.

Or use secret words that wouldn't look so obvious . And don't forget to use a rubber .

And that ladies and gentleman is the best form of birth control and a great barrier method. Sorry op

OP could still be on his moms phone plan which would enable her to read them from her own device. That seems like a possibility considering she was "dropping by", most likely to his place.

Next time don't answer the door until you are finished, then you and your girlfriend answer the door buck naked, both of you with baby batter dripping from your privates. Bet she won't do it again.
