You have sex

“Erm well I’m not going to say no to that last one” you mumble nervously causing her eyes to sparkle.

“Oh great Master John. I’ll be happy to” she replied, walking up to you and undoing your trousers.

“What kind would be you like? Oral? Anal? Vaginal? Perhaps you we could try out these new breasts you gave me?” she suggested as if she was suggesting flavours on a cake.

“I like the sound of using those tits” you reply as she pressed them against your cock. Then she began to rub against your member, and you felt it swell. They pressed softly against you, yet were large and firm.

“Do you like that Master John? Perhaps you would like it if I stroke your testicles as well?” she asked as she rubbed her huge breasts against it.

“Sure” you gasp as one hand moved to do just that. Her fingers were cool, and it almost felt ticklish the way she stroked you. The way her breasts also pressed against your groin also drive you mad with desire.

It wasn’t long before you felt yourself beginning to cum, and when you informed Siren of this she practically squealed with joy.

“Do you want me to taste it?” she asked, again so innocently “or would you like me to rub your semen into my skin?”

“Um the later” you too which she smiled. Pressing her tits against your cock with an almighty squeeze, painting her tits white. Her only response was to thank you and begin to rub it into her skin, as if it was suncream.

“Anything more John?” she offered.
