Shen Qinglan chuckled, pressing her aunt's hand on her own chest: "Touch me, just like... hm... just like when you do it yourself..."
Shen Wanqing's fingers trembled as if electrified, but suddenly tightened when touching her niece's erect nipple!
Chen Nan watched the similar features of the aunt and niece lean closer, Shen Wanqing's lips almost brushing Shen Qinglan's earlobe; his waist tightened involuntarily and suddenly thrust half an inch!
"Ah!" Shen Qinglan let out a short scream!
Her warm and moist inner parts wrapped around him as if alive, tighter than usual.
"Too... too deep..." she panted, yet lifted her hips to greet him: "It's all auntie's fault... making me so wet..."
Chen Nan began to thrust slowly, deliberately grinding over that protrusion with each entry!
Shen Qinglan's moans rose sharply, her legs unconsciously wrapped around his waist!
This angle allowed him to penetrate extremely deeply, clearly feeling every fold inside sucking him in!
