Bobbie shook his head, “Hold on a sec. If I move right now I’m going to cum.”
“No, no can’t have that,” she snickered. “In the meantime, why don’t you come down on top of me? You can get off your knees and I can feel your warm body pressing down on me.”
Sam was already laying on her belly with her ass arched up to accept Bobbie. We watched him stretch himself out on top of her.
“Yeah, you’re all nice and warm on top of me,” Sam sighed as his body covered hers, “Follow me for a sec? I want to readjust a little.” Sam wriggled to rotate her butt about 30 degrees towards us. Bobbie, crammed into her ass, followed her.
Shrewd little Samantha quietly lined herself up with us. It gave us a direct and graphic view up their bodies of Sam’s ass stretching to take Bobbie’s cock. Sam’s vacant pussy was shining-wet with her arousal.
The view got even more graphic when Bobbie slowly withdrew and then gently slid back into Sam’s ass. His balls bounced against her open pussy with a soft, moist smack and she moaned happily.
Heather and I were staring at her brother sodomizing Samantha barely two feet away. I couldn’t resist, I leaned forward to whisper into Heather’s ear. “It’s hot seeing them like this isn’t it?”
“Yeah.” Heather whispered back, sounding like she was in a trance.
“He’s fucking our girlfriend.”
“Yeah,” she repeated.
“Sam likes it too. See how wet she is?”
“Uh huh, she’s dripping down onto the bedspread now.”
“You feel pretty excited yourself. You turned on?”
“Totally.”
“Does watching your brother have sex turn you on?”
There was a long pause. “I think so. Am I sick?”
“Maybe a little,” I chuckled softly, “but in a good way.”
I held Heather by the hips and matched Bobbie’s slow, steady pace screwing in and out of Samantha. When he thrust into her ass, I pushed into Heather. When he pulled out, I did too. The synchronized action made Heather moan. If I didn’t know better, I’d have said she was fantasizing about being in Sam’s place.
“You want what Sam’s getting?” I let the double entendre hang, I could have been referring to anal or incest or both.
Heather either didn’t catch my implication or she ignored it, “You know I love you in my butt, but stay in my front a little longer. I’m gonna come soon.”
We watched Bobbie fuck Samantha’s taut little olive-skinned rump, his nearly eight inch length sawing in and out of her rectum. He was driving into her firmly enough that they pressed down into the mattress at the bottom of each stroke.
Still watching her brother’s pistoning cock, Heather leaned down onto her elbows and arched her back submissively in a pose that mirrored Sam’s. I sank myself in and out of her steadily.
Heather’s new position also put her close to one of Sam’s feet. She kissed Sam’s foot and nibbled at her heel. In response, Samantha giggled and moaned from beneath Bobbie. Sam pointed her toes and twitched happily as Heather obliged by sucking her first two toes into her mouth. She licked between them and around them.
I’m not a foot fetishist, but it was a final bit of debauchery that perfected this depraved scene. And I felt my balls stir, “Need to come soon,” I warned Heather.
