They can't sleep, fuck more
From Torg Adventure
An observer might think the two siblings-turned-lovers would fall asleep at this point, but the intense feelings in their young bodies prevented sleep from coming. Before they had recovered their breath, Jenny rolled on top of her brother's body and slipped him inside her cunt again.
"That's wasn't enough jizz, Jimmy. My cunt is still burning for you," Jenny said as she bounced above him.
"I ache to fill you, sis. Now bring those gorgeous tits down here," Jimmy said as he pulled her down, so he could suck her nipples.
She complied with his suggestion, leaning over him and sticking a nipple in his mouth. She moaned loudly when he sucked it. She bounced faster on his shaft, and the tip hit her sensitive G-spot, pushing her faster toward another huge orgasm. The drugs made fucking so urgent that thoughts of incest never occurred to them. Only their need for fucking and orgasms remained. He thrust up into her as she pushed down, getting a wicked rhythm going. Their bodies slammed together with a loud slap each time. Their grunts and moans filled the room.
"Oh, God, Jimmy, fill me up! I need your hot cum to put out this fire in my loins! Please! Squirt your junk inside me!" Jenny implored her brother.
"I'm gonna fuck you all night if that's what it takes," Jimmy replied, then he rolled over, taking his sister with him. He ended up on top of her again, thrusting, having kept embedded in her hot slippery cunt. She squawked and squealed as he hammered her sex, bringing them both closer to exploding.
Jenny arched her back as her body convulsed through another enormous climax, her screams of ecstasy echoing through the room. Her pounding pussy pulled Jimmy's cum straight out of him, and he roared over her head, his cock shooting hot jizz deep in her willing womb. They both came for several minutes, Jimmy's balls working overtime from the drugs in his system.
Once they were both spent, they collapsed to the bed, panting like they'd run a marathon.
What now?
