The prank on my sister didn't go according to plan and ended like this...

Took all the sex toys from his sister to get her to agree to incest

"Well, since your boyfriend is a cuckold and doesn't mind cheating, so help your brother out."

Accidentally came in a glass of juice, and my sister drank it and wanted more

Daughter misbehaved and ran into her father's penis as punishment

Sis was embarrassed for a long time, but she sucked her brother's dick in the entryway

Wanted only to jerk off to his sleeping niece, but snapped and fucked
