Mmmm you're doing great.  Use a little more tongue.  Mmm that's it.  You sure you haven't done this before?  Mmmm mwah.  I think that went really good.  You're an excellent kisser.  I'm glad my stepson told me about your situation.  You want to impress your new girlfriend but have no experience.  My idea isn't exactly conventional but it comes from a good place.  You've been best friends with my stepson for a long time so I care about you a lot. Sooooo I hear this Friday is you and your girlfriend's one month anniversary.  She's likely expecting, um, you know WHAT.  You're a virgin, I know.  Feeling nervous is totally natural.  You're a great guy and deserve to know how to please your girlfriend.  It's in my nature to help.  Oh my, you're even bigger than I anticipated.  After practicing with ME today you'll know exactly how to satisfy your girlfriend.  She's gonna fucking love it. Oh you're a good one.
