My GF's roomie offered me some tips on snatch eating and penetration!

I was fucking my girlfriend when out of the blue, her roommate walked in on us right in the middle of sex! We didn’t understand what was going on, until this babe explained herself, claiming this babe just wanted to help her roommate have good sex and that that babe was there to aid and train me! Can you make no doubt of that? As it turns out, this babe had been overhearing us having sex and noticed that my girlfriend was always quite quiet, and knowing that I’m lame in bed, it probably meant I was having far more fun than her! I still had my dick inside my girlfriend, as her roommate started coaching me right there on the spot! She told me I had to spread her legs far more open, so I could penetrate her deeper, and judging by the look on my girlfriend’s face, her roommate had a point, so I decided to swallow my pride and let her trainer me. After all, having her in the bedroom watching us during the time that exposed and fucking was really a turn on! Things got hawt when this babe stripped naked and joined my girlfriend in bed, ready to coach her on sucking my cock! Two undressed cuties started blowing me together, I couldn’t make no doubt of it! This sex coaching session was quickly turning into a sexy threesome fuck with my girlfriend and her incredibly beautiful, and very sexual, roommate! This babe wanted to give me some tips on proper pussy eating, so that babe made my girlfriend lie on her back and widen her legs, eating her out while down on her hands and knees, likewise prompting me to permeate and fuck her doggie style from behind during the time that that babe ate my girlfriend’s pussy! Next, this babe got on top of my girlfriend and the angels the one and the other spread their legs so I could take turns fucking one as well as the other of 'em in tandem! While I fucked them, they masturbated each other! I took turns eating 'em out, starting with her roommate, taking all her pointers and applying them to my girlfriend. After fucking both of 'em in several poses I was ready to blow my load, blasting lots of hot and creamy cum all over their beautiful faces, their open mouths and their hot undressed bodies! I erupted like a volcano! The girls' faces were overspread in white spunk from their forehead to chin. I still have a lot to learn, so now we always have sex with her roommate coaching us!
