She stays

Your aunts face is mix of fascination and apprehension. Her eyes look away only to revert back to you, Watching, as your cock becomes enlarged by your hand.

You see her steadily becoming engrossed by your performance. You stop stroking your cock and squeeze it in your hand, accentuating its substantial growth.

"It looks huge, doesnt it?" You ask her.

You get no response. Her eyes are just fixed on your cock.

"You could come over with me on the couch, if you want to." You say scooting over a little.

Thats when she makes eye contact with you again.

"Its up to you."
