Just a few more tugs...

Every nerve in your rock hard cock is crying out for you to stuff it inside her... but she is your girlfriend's mother.

You dearly love your girlfriend Claire, but you can't help thinking that you two are too much of a mismatch, what with your insatiable sex-drive and her prudishness - is that too much of a shallow reason for you not to be together or for you to seek your sexual satisfaction elsewhere?

Whatever the answer, you certainly shouldn't seek your extra-relationship sexual kicks from her family! (At least no more than you already have done! Whoops!)

And also she is a married woman and she might not even know it's you who is poised with his cock out behind her and fingering her pussy right now - plus her husband may return at any minute!

Decision made, you can't do it! Just a few more tugs and then retreat back to your room for a wank right?
