“You going to give her a nice big load of cum up her butt soon little bro’?”
Bobbie, red-faced, nodded.
Pinned beneath him, Sam eyes slid closed, focusing on the sensations in her ass. She was glowing with a light sheen of sweat as she followed him towards her third orgasm.
“You ready for my brother’s cum in your ass, lover?”
Sam grinned wickedly, eyes still closed. “Yep. He’s fucking me so good, girlie. He’s got the perfect cock for this. He’s going to make his girlfriend very happy. For her sake, I hope she likes anal so she gets the chance to appreciate this.”
Sam twisted her neck upwards to kiss Bobbie. Their tongues twirled openly as Bobbie steadily reamed her. She broke their kiss to urge him on.
“Go ahead Bobbie. Come in my ass. I can’t wait to feel your shaft swell up inside me. Then your tip will flare out too. Then I’ll feel your hot cum spraying the walls of my tight little hole. I love that part. Do it. Do it while your sister watches. It’ll make me come again.”
Sam’s plea set Bobbie off. His toes curled as he grunted and plunged deeply into Sam’s upturned rump a few more times. Then he growled and fired way up into her ass. True to her word, Sam came with him, grinding upwards to bury as much of his length as they could cram into her. They both panted together for several long minutes. Sam’s head plunked down onto the pillow under her heavily. Bobbie carefully eased his cock from between Sam’s slender little buns and rolled off of her.
Bobbie had used Sam’s ass well. Her little ring stayed open, pulsing for a few long moments before it slowly recovered and closed. We watched some thick white cum dribble from her hole. Sam held still and let it roll down over her sex and drip onto the bed beneath her. She was looking back at Heather evilly, letting her girlfriend see the raunchy result of Bobbie’s anal conquest.
Now that everybody had their fun, I sort of figured we would be wrapping up this strange little event.
Heather, still grinding back softly onto my half-hard cock, had other ideas.
Her eyes were locked on her brother’s erection – by some miracle he was still hard. Ahh, to be a teenage guy again. Heather looked at Sam. Samantha leveled her intense gaze on Heather and then she shook her head. She knew what Heather wanted. Hell, even I knew what Heather wanted.
Sam shook her head again more emphatically. She rolled over onto to her side and pulled Bobby’s cock, fresh from her ass, into her mouth. Bobbie shivered in a mixture of surprise and gratitude. With his shaft half-sank in her mouth, Sam looked back down at Heather and shook her head again.
But Heather nodded again. “Yeah, I’m going to.”
“I really don’t think it’s a good idea,” Sam sighed. But she moved herself out of the way.
“Maybe, but I’m doing it anyway.”
Heather touched her brother’s shin. “Okay Bobbie, ready for another lesson?”
Bobbie glanced down at his own unflagging erection. “Not sure. I guess, maybe parts of me are.”
She started rubbing her brother’s leg affectionately, “I’m thinking you shouldn’t leave here without learning how to make love to a girl.”
