"Isn't this just a little bit cheating?" Her sister, knowing I'm a virgin, tempts me with all sorts of things... To be honest, she's a super beautiful older sister, so it's really nice, but she also has a girlfriend... "It's cheating if you go all the way, but if it's just the tip, it's okay!" Teasing with her pussy rubbing against my glans, leaving me on edge. Hiding from her, sneaking in little insertions in various places! Isn't this cheating... (sweat)
