As Biff fucked June, he watched Marge and Sandy, who had moved to the floor. They were kissing, and feeling each other's tits. Their bellies were pressed together.
Marge then began sucking her daughter's tits. And just as Biff expected, Marge finally swung around and put her head between Sandy's thighs. Sandy's head went between Marge's thighs.
So as Biff came in his mothers cunt, he had the thrill of watching Sandy and Marge eat each other.
Before Biff pulled his prick from June's cunt, he and his mother watched Sandy and Marge lick each other's pussies to orgasm.
Now that all four of them had had at least one orgasm, they got dressed. June offered to make coffee, but Sandy and Marge said they had to be going.
"Well, we'll have to get together again real soon," June said.
When Sandy and Marge left, Biff and June went to their own rooms. At dinner, neither of them spoke about the orgy they'd had.
Biff didn't feel like calling Sandy. And she didn't call him. Nor did Marge call June. And before they knew it, it was time for Biff to leave for his first year at college.
Only after Biff was away from home did he find another girlfriend. He took her out three times before he even tried to kiss her. She almost gave up on him. But Biff knew that things could get out of hand very easily. Maybe he was just an old fashioned boy. But all he wanted was a nice girl he could fuck a few times, a week.
After all, apple pie tasted best when one hadn't had any sweets for a while!
