I stood in front of them, my son grinning broadly at me while Marcus, still kneeling forwards with his hands prizing his arse-cheeks apart, peered over in wide-eyed horror.
"I just happened to see your light on and wondered what was keeping you two guys up," I said by way of flimsy explanation.
"Of course you did," Jake chuckled, and I was unable to stop myself from smiling back at my son in spite of his state of nudity. I made an effort to keep my eyes from making contact with his erection which he was brandishing flagrantly as if showing it off in some sort of macho display.
Marcus, meanwhile, struggled upright and away from him, and ended up crouching almost foetally against the headboard of the bed, trying to cover his genitals with both hands.
"I... er... I'm so sorry, Mr Furlong," he stammered, his face blushing a deep purple colour which nicely co-ordinated with that of the swollen head of his penis. "We were just messing around... and I... er... slipped... and Jake's tongue must have accidentally --"
He stopped when he saw that I was amused rather than angry and I did my best to reassure him, "It's okay, Marcus -- really. I think the point my son was trying to make was that there are two Furlong mouths in the household."
Marcus stared at me, wide-eyed and with face flushing so dark it looked like he had been slapped on both cheeks, seemingly still unable to understand the idea which Jake had been mooting.
"I hope you appreciate, dad," Jake cut in before Marcus could formulate a reply, "how good it is of me not to hold grudges. I could so easily have ticked you off for spying on us and then sent you away, just like you did when you were in my shoes."
"It is indeed very noble of you, Jake," I smiled. "I'm proud of you."
I realised that the front of my pyjama bottoms were still being pushed outwards by the semi-hard-on I'd developed before I'd entered the room but I made no attempt to hide my excitement. Marcus peered at my unconcealed bulge with continued bafflement at first, before it finally began to click with him what was going on. At that point his gaze shifted from my crotch upwards to my face and he stared at my expression as if trying to figure out what exactly my motives were.
Jake got up off the bed and walked over to the chair in front of his desk and sprawled himself out naked on it, adopting an especially indecorous posture given his lack of attire. He seemed totally unbothered by the fact he had a very large hard-on, the shaft of which still bore some of the remnants of where it had so recently been, nor that his large pair of bollocks hung down gracelessly between his wide open legs.
He was far more keen to underline his self-righteous sense of magnanimity. "I mean, when I was a kid, you always told me how important it was to share. And some of us are very willing to share, even though you were so blatantly uncaring and unsharing last week!"
"I get the point, Jake," I retorted. "It just felt wrong last week... what you were suggesting with Bradley. Now -- I dunno -- it feels somewhat different."
I smiled at Marcus, hoping my expression didn't look too lustful or predatory, but he continued to look wary and kept his genitals well-protected by cupping them in both hands.
"Yeah, I wonder what could have caused your sudden change of heart," Jake chuckled as he scratched his large, hairy scrotum, and glanced towards at his extremely attractive young friend.
"Would you be happy for me to take up Jake's offer, Marcus?" I asked, hoping to ease his discomfort with a more direct approach. "And offer you a second mouth for your... er... continued pleasures?"
"My dad is, like, the best rimmer ever," Jake bragged, apparently oblivious to his friend's feelings of awkwardness. "He can probably get his tongue all the way up to your liver!"
Marcus looked over at me with even more embarrassment. How did a person respond to such an accolade about your friend's father when he was standing half-aroused in front of you?
"You've really got to get rimmed by him, mate," Jake went on. "He's so much better at it than I am!"
Well, he was right on that point.
"How do you know that, Jake?" Marcus asked with the same obvious unease.
"I saw him rimming a bloke downstairs on the couch one night. His tongue was so far in there, you wouldn't believe it! It was like --"
"Alright, Jake! I think he gets it!"
"You actually rimmed another man in front of your son?" Marcus asked incredulously.
Jesus Christ, he was going to be calling Social Services next.
"Jake has a tendency to interrupt my... er... soirees," I explained. "It wasn't like it was a performance I'd arranged especially for him to see."
I threw a pointed glance at Jake to let him know I was aware that his game tonight had been precisely that.
"But you have sex with other guys?" Marcus attempted to clarify, distractedly taking his hands away from his crotch. His cock had completely withered from its earlier glory and was looking disappointingly shrunken as it flopped against the fair, downy fluff on his balls. It was still rather lovely, though.
"Would it be a problem if I did?" I asked.
"Of course not," Marcus said, with a half-hearted smile. I sat myself down on the bed next to him in the spot Jake had vacated. There was a wet patch on the duvet from where my son's stiffie must have been dribbling as he'd made a pigs-ear of rimming his friend.
"It's just that it came as a bit of a shock when you walked in," he went on. "I knew you were divorced but I didn't realise you were... how would you call it... bisexual?"
