I successfully reconciled my constantly fighting sisters by giving them a forbidden aphrodisiac, which turned them into intense lesbians! But maybe the aphrodisiac was too strong? Their overly erotic lesbian play got me fully erect! And when they noticed me, I got pulled in and ended up kneading and licking their sensitive big breasts! I kept alternating thrusting into their slippery double vaginas! I thought I couldn't do it, but I gave in to my desires and ended up having a forbidden 3P incestuous relationship.
