This role-play is performed by adults. When I returned home for a family gathering after a long time, I was surprised to see that my sister's daughters had become so cute! The two become attached just like before, but their bodies have grown into adults... Still, just like in the old days, he comes to the guest room in his pajamas and says, ``Sleep with me!'' I can't sleep between the two of them, and my sister notices my erection and starts playing tricks on me! Moreover, he attacks my lower body from both sides with techniques that rival adults! As expected, my rationality collapsed and I got involved...
