Heidi couldn’t help herself; she bent over Johnny and enveloped the sensitive head of his cock in her warm wet mouth, and licked it with her tongue. It felt incredible to Johnny, but suddenly she released him and positioned her sex over him.
“Do you have one more shot of cum for me, Johnny?” Heidi asked, as she lowered her cunt over his big stiff boner, enveloping the whole length of his cock inside her tight pussy. She rhythmically squeezed his cock with her pussy with each stroke as she slid herself over him; up and down she rode his prick, again and again.
Johnny was content to have Heidi fuck him, he was so damn tired, and it felt so good. And it was so delicious to be watching Jan, to be seeing her finger her pussy and rub her own legs and tits. He shifted one of his legs so that his foot rested against his sister’s naked ass, savoring its softness.
Jan frigged herself off as she watched Johnny’s big prick disappear into Heidi’s pussy lips, inch by glorious inch, again and again. It wasn’t right though, she wanted Johnny’s cock to be inside her, not inside Heidi. She ran her hands over his muscular legs though, feeling them tense with each stroke of Heidi’s pussy. When he put his foot on her pussy and clumsily rubbed it, she grabbed it with both hands, pressed it against her pussy mound, and rubbed it against herself. The bottom of his foot mashed her juicy cunt lips and clit. She was fucking him at last, she felt, fucking her twin brother Johnny! Soon she felt herself cum as she held Johnny’s foot tight against her convulsing cunt.
“Fuck, fuck, fuck!” Johnny said, as Heidi fucked him, and kept fucking him. This time, it seemed to take a long time, but at last his cock throbbed and he shot hid cum deep inside of her wonderful soft clutching pussy. “Ahhhhh,” he moaned. He felt content and exhausted.
Heidi used her practiced fingers on her clit to help her get to her own orgasm. She too was tired: it had been a very long day. She felt Johnny soften within her and she kissed his lips. “Rest now, Baby, she told him. You deserve a rest.” Johnny smiled and quickly fell asleep. Even teenage boys had their limits. He was just like Mike, Heidi realized. After a hard day of fucking Mike dozed off and slept soundly for the rest of the night. Johnny had earned his sleep. Let him rest up for tomorrow. Tomorrow she had plans for him and his twin sister.
Jan was exhausted herself. She watched numbly as Heidi put a sheet over Johnny and kissed his cheek goodnight. Johnny was soundly sleeping on the sofa. Then she let Heidi lead her to the big soft king-sized bed where Heidi and her Daddy had fucked each other earlier, and lay her down. The bed smelled faintly of Daddy sweat and cum, and seemed to still be warm from Daddy’s naked body. There were also two little pairs of panties on the bed that seemed too small for Heidi or herself. She almost asked Heidi about them but didn’t. She was exhausted and needed to sleep. Still, she didn’t protest when her stepmother spread her legs wide and gently licked her pussy with her soft tongue, alternating between pussy and clit. Gradually she was aroused yet again, and the savored the licking tongue for what seemed like hours. When she at long last had her final orgasm of the day she felt content as she drifted off into sleep, except for one thing that nagged at her. She was still a virgin.
