Peter moans: "AH! AHAH!"
Sonic quietly says: "be quiet, you dumb fat idiot! You'll wake up Lois..."
The two lovers commit anal pleasure in the Griffin house. Sonic thrash his 7 feet (about 2.2 meter) penise inside Peter's butthole at the speed of sound for nearly two hours.
Peter saying, nearly crying at the same time: "maybe next time we'll use lube ok?". Sonic slaps Peter in the dick and in an evil laugh say: "next time I will use sand paper you whore!" Peter nods his head in approve. Peter quietly moans: "I think Stewie is looking at us from upstairs!"
Sonic quickly take a look at the basement door and sees Stewie fapping to them. Sonic Blushes but still fuck Peter so hard there is blood splashing all over the basement where they were "having fun". Peter tries to kiss Sonic, but then Sonic quickly hit Peter with a blunt object. Peter faints. Sonic smiles and quietly say: "at least he'll be quiet now". Stewie runs towards Sonic and while still fapping he says: "if you won't lend me room in Peter's dead butthole I'll call Lois!". Sonic, realize he has no choice but to give Stewie some space at Peter's bumhole. Stewie rushes towards Peter's ass, and insert his 2 inches dick into his analhole. Stewie, still a baby, has failed to hold his cum, and after ten seconds he cum inside Peter's ass. Sonic is disappointed. Stewie, so ashamed at himself, decide to take his own life in a Japanese style (Harakiri). Sonic finds it very erotic, so he quickly splash his sperm inside Peter's buns. Sonic was the only survivor of this beauty threesome. FIN
