My twin sister catches me washing my squirt covered sheets... and I have to tell her the truth. When I tell her I have been squirting lots, she seems so curious and since I will always look out for my twin sis, I offer to teach her! I tell her how to pleasure her pussy, we watch each other squirt and I even squirt a second time watching her have her first squirt! It's a secret only twins could keep... it's just between us
