In Karl's ballsac

He shuffled forwards and pushed his cock into the folds of warm skin of his balls. With one last stroke he came, a huge shuddering orgasm. His six inch cock was about half covered by the scrolls of flesh, and he could feel the sperm sliding down inside the folds of Karl's massive balsac.
"well... that was new, did you think of that yourself?" Panting, Brent nodded. "Feels nice." the trio sat there, soaking up the post orgasmic atmosphere. The musky smell of cum and sweat. The quiet sounds of brent recovering. Sam sat there, staring in awe. What an amazing experience this was. She started stroking herself again, soaking up the aura of what had just happened.
"Guys... I've never seen anything so powerful" Karl just looked at them, lust washing through him. These were the most erotic moments of his life, bringing this womans husband to orgasm in fromt of her... Dam he was so horny! he grabbed Brent's hand and placed it on his cock. The wolf looked down and started squeezing it. He started at the bottom and worked his way up the ample length. Each squeeze caused Karl to tense up and flex his cock. He would last about 30 seconds at this rate. Sure enough, on Brent's 2 pass of his cock, Karl began bucking on the bench. He quickly worked the equine now, rapidly jerking him off. Karl blew everywhere. Brent was masturbating him with such **** that his cum went everywhere, all over himself, all over Karl, all over the sauna. It even splashed onto Samantha, something she wasn't quite prepared for.
With the two males in the room spent, energy levels droped. The trio lay there basking in the glow of the heater, feeling Karl's sperm matting their fur.
