A long session!

Knowing Sebastian's favorite position, you get behind him and start teasing him, rubbing your cock up and down, occasionally letting your cockhead catch in his well-lubed asshole. After teasing him once more, you ease your thick cockhead into Sebastian's greasy entrance, making the young twink grunt as you enter him with a loud 'POP'.

Sebastian groaned as you eased the rest of your cock into his hole, only stopping when you feel his meaty bubble-butt up against your rock-hard abs. Sebastian looked back at you shyly and nodded his readiness to continue, you smile back at him and placing your hands on his hips start thrusting forward at an ever increasing pace, making him groan in ecstasy as you rub his sensitive prostate.

"OH, GOD! SO FUCKING GOOD!"

You grin as you continue to fuck Sebastian, alternating your pace until you feel him shudder and whimper as you feel his ass tighten up on you as he cums for the first time. His head drops as he tries to catch his breath, not that you were going to allow that!

"I want you to cum again and again for me Sebastian... I want to drain your balls!"

"Oh, God!"

To prove your point, you angle your cock so that every time you thrust in and out, you were hitting his prostate, making him whimper loudly every time. It's not until you look up that you realize that there's a mirror facing the bed, softly grabbing Sebastian by the hair, you make him look up and watch as he gets fucked, you notice his increasingly sweaty, red face as you make him exert himself more with you fucking him better and for longer than he ever had been at high school or college.

Thirty-five minutes later...

Sebastian whimpered to you that you'd succeeded, his balls were running on empty. You smiled as you told him to watch as you filled his womb up and bred him. Sebastian moaned at the thought of you breeding him and watched intently as you started really pounding his ass. You started breathing heavier as you get nearer to your climax, what sent you over the edge was Sebastian licking his lips, feeling the tingling in your balls, you push your cock as deep as it will go inside your young lover and roar out your release, making Sebastian cry out as he feels your piping hot cum flood his womb, your cum fills him up so much that some starts to leak out.

"Do you have a butt plug?"

Sebastian leans over the bed and quickly grabs one and hands it to you, moving quickly you pull out and insert the plug, making sure that as much of your cum stays in his ass as possible. Walking back around to Sebastian's face, you offer up your semi-flaccid cock for the young Brit to clean off which he does eagerly.

"Next time I come here you and I are going to fuck for at least an hour, and in multiple positions..."

Once the two of you caught your respective breaths, you both made your way to the shower. After your joint shower (with plenty of touching), you got dressed and headed home, leaving a slightly hobbling Sebastian behind.
