Pained moans, deep grunts, and slurping sounds were the only things that could be heard inside my truck, and I just noticed that Riri was having a hard time going down on the last few inches of my cock.
Riri was clutching hard at Ruru's hair while the other was almost clawing at my arm while I kept groping her nice tits and pinching her nipples between my fingers.
Her body would tense and slightly tremble each time she tried to lower herself even more but she would twitch each time Ruru's tongue hit a specific spot in her pure flower. With that said, I could hear the sounds Ruru's pussy made since she was also touching herself while she was eating her own sister.
"MmMh! Mmh! Ah! I-Is it— D-Did I t-take it all i-in?"
"Haa… Haa… A l-little more s-sis… Do you want me to—"
"P-Please!"
