With a tit fuck.

Lisa kneels down between your legs and stares at your throbbing erection, seemingly unable to decide what to do with it. With a determined sigh, she cups her small breasts and smothers you cock with them. You lean back in the chair and enjoy the sensation of her soft mounds of flesh caressing your shaft like an angelic handjob.

"You like it?" she asks timidly.

"Yeah," you moan.

She giggles at your approval and continues until she notices a bit of precum leaking from your cockhead. Then much to everyone's surprise, especially you, Lisa bends her head down and wraps her lips around your sensitive tip and swirls her tongue around it.

"Holy shit!" you gasp as she sucks on your cock.

"Do you like that?" she asks after popping your cock from her mouth with an audible pop.

"Fuck yeah!" you groan with a stupid grin.

"Okay, it's my turn to thank Mark!" Sara blurts out and Lisa uneasily shuffles back to give her space.

You suspect Sara is a bit jealous of her neighbor and wants to one up her.
