Cassie can't find them

Emma starts out slowly licking all over your cock and gently stroking your dick. After you are rock hard she starts going faster, slipping up and down with her hand and her mouth in unison. She feels so good you forget about the scene and just lay back enjoying it. Before long you are getting close.

Cassie comes strolling back in empty handed. "I couldn't find any." she says in her ditsy airhead voice.

"Oh my god!" Emma exclaims. "What are you doing in here? Cant you see I'm sucking my boyfriends dick?"

"Can I help?" Cassie says with her innocent looking smile.

"Well it is his birthday, maybe we should do something special for him. How about a threesome" she suggests.

Cassie comes over immediately and straddles your hard cock. "Don't cum, seriously" she whispers. Then she starts riding your cock cowgirl style.
