In this fantasy I place an ad in an M4M section of an online site.  The ad reads: "Very bi-curious married male seeks well-endowed male whe needs oral satisfaction.  Drug- and disease-free a must.  Picture required for response.  I promise full satisfaction."   I receive several responses, but one picture gets my full attention.  It shows a long, thick, uncut erection with just the tip of the cock-head showing.  The man advises that he is divorced, doesn't do drugs and is disease-free.  We text back and forth a few times, and arrange to meet at a commuter parking lot near an expressway.  He has a small motorhome that we can use.  The time of the meeting approaches, and I am very nervous.  I have never done this before!  I drive to the location and his motorhome is parked at the far end of the lot.  My heart is pounding as I park nearby and walk to the motorhome.  "Bruce" opens the door.  We are using different names for this first meet.  I go into the motorhome and Bruce closes and locks the door.  He is dark-complected and heavy-set, good-looking and very polite.  We exchange small talk, then begin talking about the ad.  He suggests we go back to the bedroom and undress to begin with, and I agree.  I know I'm blushing as we undress.  We face each other, totally naked, and I see that his picture was not faked or enhanced.  His cock is ...... big!  We sit next to each other on the bed and he pulls my hand to his semi-erect cock.  My heart is racing as for the first time ever I hold another man's penis!  It erects as I fondle it.  I slide the foreskin down, revealing the big cock-head, then up again.  I am becoming very aroused.  I begin to stroke it slowly, and Bruce moans huskily.  He gently urges me forward, smiling.  I kneel in front of him and he opens his legs.  I slowly len forward, slide the foreskin back..... and let the swollen cockhead slide into my mouth.  He groans as I begin to suck on it.  I stroke the thick, throbbing shaft and my other hand gently squeezes the large taut ball-sac under his cock.  I taste his pre-cum as it oozes from the tip of his cock-head.  Bruce's hips begin to thrust slowly, setting the pace.  I gradually let the head go further back in my mouth with each thrust, until I have over half of his long hard cock in my mouth.  I stroke the cock more rapidly.  Bruce is moaning louder...  "I'm ... gonna ... CUM!" he gasps, and a huge stream of his cum squirts into my throat!  I swallow, just as a second, and a third spurt shoot from the bloated cock head.  I swallow every drop, milking the big shaft as Bruce collapses back on the bed, moaning.  When I have sucked and swallowed every bit of his cum, I raise my head and smile.  It was a fantastic "first time".  We arrange to meet again.
