MIAA-018 Shove it in all the way! She's driving him crazy by only letting him enter just a little bit, while he endures life cheating with her sister. Yui Hatano

"Isn't this level okay for cheating?" Her older sister, knowing I'm a virgin, starts tempting me in various ways... Honestly, she's incredibly beautiful, so it's quite enjoyable, but I do have a girlfriend... "It only counts as cheating if it goes all the way in, just the tip is fine!" She rubs her vagina against my glans, teasing me mercilessly. Hiding from my girlfriend, I keep sneaking in little insertions in various places! Is this really not cheating... (sweat)
