Prank You Very Much!

Ricky Spanish plays a prank on his stepsister, Eliza Ibarra, by replacing her glasses with a similar pair without her knowing. Eliza, tired from a late night with her man, puts on the fake glasses and ends up with a blurred vision. Meanwhile, Ricky is scheming for more fun.
Tricking Eliza's boyfriend Elias Cash into leaving without bidding her farewell, Ricky slips into Eliza's room, donning one of Elias' tops. Confused by her obscured view and thinking Elias is still around, Eliza mistakenly plants a kiss on Ricky's cheek, unknowingly falling into Ricky's trap. Later, a nude Ricky waits in the bathroom doorway, eagerly watching for Eliza's arrival.
Hastily showering as she comes closer, Eliza joins him under the falling water, misidentifying Ricky as Elias yet again. Ricky takes advantage, delighting in shower-time intimacy. Another time, Ricky sneaks into Eliza’s empty bed, pretending to be her boyfriend when she returns.
Unfortunately, Eliza realizes the switch while riding Ricky and notices a significant difference in the size of Ricky's manhood. Though initially upset, Ricky persuades Eliza to continue the encounter.
