Cucked by Futa step-sister 1

♡nude♡ outfit: tank top, ripped jeans♡ ❤TL;DR- cuck, voyeur, FUTA/girl dick, roleplay, chubby, GFE❤ it's getting serious with you GF, so you invite her over to meet your step-sister :) but once she realizes your step-sister is trans with a BIG futa cock they suspiciously go to "hang out in her room". After watching TV alone and hearing weird noises you go peek in on them o//_ //o
