I saw my twin sister Goba masturbating in VR, so I went with the momentum and asked her to let me touch her tits. 'We're siblings! That's impossible... but just a little bit then...' she couldn't hold back her curiosity for sex... Finally, they reached the point where only the tip was inserted, and decided on the rule that 'inserting up to 3cm doesn't count as sex,' repeatedly having head-only sex. However, even just the tip going in and out felt incredibly good, and they started wanting to insert it deeper… Twin siblings' life on the brink of elimination, fucking non-stop!
