I was a bit scared but yeah, I’d do that for my bird. To be honest, I thought I’d be the one shagging Gavin but no, if my girlfriend wanted to see...Gavin shagging me then that’s what she’d see. And anyway, Gavin’s tongue felt amazing up my bum, just think what it’d feel like with his cock up inside me.Next thing Gavin took his tongue away from my arsehole. I heard him spitting on his dick. My bird was getting proper excited now. She got in real close.“I’ve gotta see this, boys!”Gavin got in. "Where's the switch?" Cooper asked."You'll find it like you found the doorknob," Bud answered smugly.We stood and scanned the walls, trying to see it the way we'd seen the basement wall, but didn't find anything. I shrugged my shoulders and started walking down the tunnel. The tunnel ran in a straight line about a thousand feet and then stopped at another door."Another door?" I asked"Same deal as the first one," Bud answered, not surprising us at all."Okay then," I said, and Cooper and I began. "Are you all wet for him or do you need some lube?" I slipped off my panties, grabbed the lube and put a generous amount on my ass. I lay back down on the bed on my back. She knelt between my legs. The sight of her hot feminine body with a big black cock pushed all my bisexual buttons. She moved up the bed until Tyrone was near my mouth. "Suck him first, Honey," she said.I opened my mouth and took the rubber phallus inside, taking as much of it as I could and playing with the brown rubber. She was moaning and panting as she tried to tell him how wonderful it felt to have him inside her.He lifted up and told her she would experience many more days and nights just like his one. He planned to fuck her continuously while her white husband was away. She smiled and kissed him as she continued to rotate her hips and pussy on his black cock still inside her. She had fallen back on the bed now and they both were covered with wetness from their sexual.Two days passed and they had fucked in.
